Early in her career, a colleague told Associate Professor Juanita Todd that schizophrenia was considered the "graveyard of the neuroscientist", so intractable had the field proven to be for researchers. Undeterred by this discouraging perception, Todd launched into schizophrenia research regardless, motivated by a fascination with the workings of the brain and a desire to make a real contribution to determining the causes of this inscrutable disorder.

"I am intrigued, in the saddest way, by the element of this illness that makes people so detached from their prior selves," reflects Todd, who completed a Masters in clinical psychology after studying an undergraduate science degree. "I have worked with families of people with schizophrenia and they will often tell you the person they knew, the son or daughter that they had, is so different to the person they see before them now."

Todd's research focuses on detecting the earliest point at which that conversion starts to manifest and honing in on the neurological changes that may be taking place to cause those symptoms to appear. She studies a brain response called mismatch negativity, an indicator of a person's sensitivity to unexpected stimuli. This automatic brain response is smaller in people with schizophrenia, a finding first established two decades ago by an Australian research team that included Todd's PhD supervisor, longtime mentor and University of Newcastle colleague, Emeritus Professor Pat Michie.

Todd uses head caps with recording electrodes to measure response to sound stimuli, to study how the brain organises information and determine how the process might differ in people with schizophrenia.

"The brain quickly models anything repetitious and learns to expect that pattern to continue. Anything that interrupts that pattern – a different or sharper sound for instance – will produce mismatch negativity, even though that deviation may or may not enter a person's conscious awareness," Todd explains.

"This mismatch negativity is also called a 'prediction error signal'. In higher-order brain processes, prediction errors are highly influential in determining what we will learn about. So what I study is a very simple, very early form of prediction error that we think may be related to these higher levels of dysfunction in schizophrenia.

"I sometimes think that what I do is like a game of Chinese whispers, in that if you can trace something back to the point where it first goes wrong, perhaps everything else that happens afterwards will make more sense. If we can find the first point of dysfunction in prediction errors in schizophrenia, then it might be possible to better understand the processes of the disorder and be able to intervene earlier with treatments."

In the course of developing more sophisticated sound sequences for measuring auditory mismatch negativity, Todd has found evidence of apparent biases in the automatic process the brain uses to filter which sounds are relevant and which are not. Todd's findings were published in the journal Neuropsychologia last year and earlier this year she presented her research in this area to a conference on mismatch negativity in New York.

"To the field, this is an unpredicted finding so it is quite exciting and has opened up collaborations with people who work more generally in the field of how we learn," she states.

Todd and Michie, together with University of Newcastle colleague Professor Ulrich Schall, have received National Health and Medical Research Council funding to continue their research on mismatch negativity in schizophrenia. In another major project, Todd is collaborating with leading University of Newcastle clinical psychology researcher Professor Amanda Baker and researchers in Melbourne on a study of how nicotine use affects cognition in schizophrenia.

"The University of Newcastle is quite a force in schizophrenia research," Todd enthuses. "One of the things I have found very valuable is the range of very highly regarded researchers here with different specialties who are all working towards the same goals. It promotes a multidisciplinary approach and encourages you to step outside of your immediate field and think about things differently."

Career Summary

Biography

Dr Juanita Todd was awarded a distinction for her PhD thesis completed in 2001. Research conducted as part of this thesis has featured in five international peer-reviewed journal articles and presentations at international conferences covering all areas of application of this work.

The outcomes of her PhD research also formed the basis for a successful NHMRC Project Grant (ID: 209828) that she co-wrote in 2000/2001, which in turn facilitated the success of a second NHMRC grant (ID: 252480) in 2002. The results of NHMRC Project Grant (ID: 209828) have recently been accepted for publication in Biological Psychiatry: (Todd, J., Michie, P.T., Schall, U., Karayanidis, F., Yabe, H. & N¿¿t¿nen, R. Deviant matters: Duration, frequency and intensity deviants reveal different patterns of mismatch negativity reduction in early and late schizophrenia. Biological Psychiatry, in press, accepted 21-2-2007. IF = 6.779) which will undoubtedly prove to be one of her most influential publications.

In 2001 CIA was appointed a Level B Lectureship at the University of Newcastle converted to a Level B Research Academic in 2002 following the success of NHMRC grant (ID: 209828). In this position her responsibilities included management of data collection and analysis and supervision of research staff for 209828, supervision of research for Honours and Postgraduate Psychology students and lecturing in fields related to her research interests. In 2002 CIA extended her research into the area of aging. As part of this progression, she developed a study of mismatch negativity in healthy aging and a group with mild cognitive impairments/early stage Alzheimers. CI supervised an Honours (R. Cooper Class 1) and RHD student (K. McGill) who completed the research component of their degrees based on data collected in conjunction with this study. These data were published with R.Cooper as first author in 2006 in Neurobiology of Aging (a high ranking journal in the area IF = 5.312).

In April of 2004 CIA was awarded a University of Newcastle Postdoctoral Fellowship. During 2004 she developed a study exploring hypothesized left hemisphere superiority for processing temporal information that forms the basis for the present application. From October 2004 CIA took 12 months maternity leave during which time she worked o the development of this area of research and contributed to the publication of her Honours work with a former collaborator.

Since her return to work (0.6 FTE in October 2005) Dr Todd has published a single author paper, a first author paper and a co-authored paper in addition to the development of grant applications and supervision and/or co-supervision of 3 PhD students.

Dr Todd's academic achievements to date are also reflected a number of awards received and professional duties. CI was the recipient of the Cockburn Domestic Council Dux Award (1990), UWA Convocation Medal, Faculty of Science (1991), 3 awards received for best debut oral conference presentation (ASPR - 1997, ASC 1999 and UWA postgraduate conference 1999) and an achievement award in the field of Psychiatry and Behavioural Sciences (from the WAAssociation for Mental Health in Partnership with the Centre for Mental Health Services ResearchInc).

She has been requested to review manuscripts for several international journals (CognitiveBrain Research, Brain Research, Psychophysiology), and has supervised the completion of research for Honours degrees by three students (N. Matthews Class 1, R. Cooper Class 1, Rik Barker Class 1) and one RHD student (K. McGill).

© 2016 Samantha J. Broyd et al.Prolonged heavy exposure to cannabis is associated with impaired cognition and brain functional and structural alterations. We recently reported attenuated mismatch negativity (MMN) and altered P50 sensory gating in chronic cannabis users. This study investigated the extent of brain functional recovery (indexed by MMN and P50) in chronic users after cessation of use. Eighteen ex-users (median 13.5 years prior regular use; median 3.5 years abstinence) and 18 nonusers completed (1) a multifeature oddball task with duration, frequency, and intensity deviants and (2) a P50 paired-click paradigm. Trend level smaller duration MMN amplitude and larger P50 ratios (indicative of poorer sensory gating) were observed in ex-users compared to controls. Poorer P50 gating correlated with prior duration of cannabis use. Duration of abstinence was positively correlated with duration MMN amplitude, even after controlling for age and duration of cannabis use. Impaired sensory gating and attenuated MMN amplitude tended to persist in ex-users after prolonged cessation of use, suggesting a lack of full recovery. An association with prolonged duration of prior cannabis use may indicate persistent cannabis-related alterations to P50 sensory gating. Greater reductions in MMN amplitude with increasing abstinence (positive correlation) may be related to either self-medication or an accelerated aging process.

© 2015 Elsevier B.V.The mismatch negativity (MMN) is conceptualized as a confidence-weighted error signal elicited when a deviation violates the predicted next-state based on regularity. The mechanisms underpinning its generation remain contentious. Smaller MMN response is a robust finding in schizophrenia and reduced amplitude may implicate impairment in prediction-error signalling. An enriched understanding of factors that influence MMN size in healthy people is a prerequisite for translating the relevance of reduced MMN in schizophrenia. This paper features two studies designed to explore factors that impact MMN in healthy individuals. Study 1 confirms that MMN amplitude does not faithfully reflect transition statistics and is susceptible to order-driven bias. In study 2, we demonstrate that an order-driven bias remains despite repeated encounters with sound sequences. These data demonstrate that factors that impact on MMN size in non-clinical groups are not fully understood and that some mechanisms driving relevance filtering are likely influenced by 'top-down' expectations.

© 2015 The Authors.Smoking prevalence in schizophrenia is significantly elevated relative to other clinical and to non-clinical groups. The cognitive self-medication hypothesis attributes this to the beneficial effects of nicotine on illness-related cognitive deficits. Significant effects of nicotine have been observed on visual spatial working memory (VSWM), sustained attention (Continuous Performance Test - Identical Pairs; CPT-IP) and prepulse inhibition (PPI). It remains unclear whether these neurophysiological and neurocognitive effects of nicotine influence self-reported smoking motivation. To explore the relationship between nicotine effects on cognition and self-reported smoking motivation in schizophrenia and non-psychiatric control smokers, the impact of smoking abstinence and reinstatement was examined across three cognitive indices (VSWM, CPT-IP, PPI) and compared to self-reported smoking motivation (Modified Reasons for Smoking Scale revised to include 'cognitive motivators'). Cognitive function was assessed after 'typical' smoking and overnight abstinence. Schizophrenia smokers (but not controls) demonstrated significantly less error on the VSWM task in the smoking relative to abstinent condition. Control (but not schizophrenia) smokers, showed evidence of CPT-IP improvement in the smoking relative to abstinent condition. The overall profile of smoking motivation was comparable between groups. However, significant relationships between subjective and objective indices of smoking related cognitive change were observed for controls. Differential effects of nicotine on cognition have been hypothesised to influence the pattern and persistence of smoking in schizophrenia. These preliminary findings indicate that evidence for such effects is apparent even in small samples - particularly for VSWM. This is the first study to show that neurocognitive effects of smoking may influence self-reported smoking motivation.

© 2015 Elsevier B.V.The aim of this review is to explore the phenomenon of reduced mismatch negativity (MMN) in persons with schizophrenia and the possible relationship it has with attention impairments. In doing so we discuss (i) the prediction error account of MMN, (ii) reduced MMN as a faulty predictive processing system in persons with schizophrenia, (iii) the role of these systems in relevance filtering and attentional resource protection, (iv) attentional impairments in persons with schizophrenia, and (v) research that has explored MMN and attention in schizophrenia groups. Our review of the literature suggests that no study has appropriately examined the functional impact of smaller MMN in schizophrenia on the performance of a concurrent attention task. We conclude that future research should explore this notion further in the hope that it might embed MMN findings within outcomes of functional significance to individuals with the illness and those providing treatment. This article is part of a Special Issue entitled SI: Prediction and Attention.

© 2014 Harms et al.Mismatch negativity (MMN) is a scalp-recorded electrical potential that occurs in humans in response to an auditory stimulus that defies previously established patterns of regularity. MMN amplitude is reduced in people with schizophrenia. In this study, we aimed to develop a robust and replicable rat model of MMN, as a platform for a more thorough understanding of the neurobiology underlying MMN. One of the major concerns for animal models of MMN is whether the rodent brain is capable of producing a human-like MMN, which is not a consequence of neural adaptation to repetitive stimuli. We therefore tested several methods that have been used to control for adaptation and differential exogenous responses to stimuli within the oddball paradigm. Epidural electroencephalographic electrodes were surgically implanted over different cortical locations in adult rats. Encephalographic data were recorded using wireless telemetry while the freely-moving rats were presented with auditory oddball stimuli to assess mismatch responses. Three control sequences were utilized: the flip-flop control was used to control for differential responses to the physical characteristics of standards and deviants; the many standards control was used to control for differential adaptation, as was the cascade control. Both adaptation and adaptation-independent deviance detection were observed for high frequency (pitch), but not low frequency deviants. In addition, the many standards control method was found to be the optimal method for observing both adaptation effects and adaptation-independent mismatch responses in rats. Inconclusive results arose from the cascade control design as it is not yet clear whether rats can encode the complex pattern present in the control sequence. These data contribute to a growing body of evidence supporting the hypothesis that rat brain is indeed capable of exhibiting human-like MMN, and that the rat model is a viable platform for the further investigation of the MMN and its associated neurobiology.

Repetitive patterning facilitates inferences about likely properties of sound to follow. Mismatch negativity (MMN) occurs when sound fails to match an inference. Smaller MMN in schizophrenia indexes deficient gain control (difference in utilizing a limited dynamic range). Although it is clear that this group has a lower limit to MMN size, this study addressed whether smaller MMN indicates impaired perceptual inference. MMN was elicited to four deviants in two sequences: one in which occurrence was random and one in which it was paired. Despite smaller MMN, persons with schizophrenia are equally able to reduce MMN size evoked by a deviant when its occurrence is cued. Results also expose alterations in the evoked response to repeated sounds that appear to be exacerbations of age-related amplitude decline. Since these anomalies impact the computed MMN, they highlight the need to identify all contributions to limits in gain control in schizophrenia. © 2014 Society for Psychophysiological Research.

Repetitious patterns enable the auditory system to form prediction models specifying the most likely characteristics of subsequent sounds. Pattern deviations elicit mismatch negativity (MMN), the amplitude of which is modulated by the size of the deviation and confidence in the model. Todd et al. (Neuropsychologia 49:3399-3405, 2011; J Neurophysiol 109:99-105, 2013) demonstrated that a multi-timescale sequence reveals a bias that profoundly distorts the impact of local sound statistics on the MMN amplitude. Two sounds alternate roles as repetitious "standard" and rare "deviant" rapidly (every 0.8 min) or slowly (every 2.4 min). The bias manifests as larger MMN to the sound first encountered as deviant in slow compared to fast changing sequences, but no difference for the sound first encountered as a standard. We propose that the bias is due to how Bayesian priors shape filters of sound relevance. By examining the time-course of change in MMN amplitude we show that the bias manifests immediately after roles change but rapidly disappears thereafter. The bias was reflected in the response to deviant sounds only (not in response to standards), consistent with precision estimates extracted from second order patterns modulating gain differentially for the two sounds. Evoked responses to deviants suggest that pattern extraction and reactivation of priors can operate over tens of minutes or longer. Both MMN and deviant responses establish that: (1) priors are defined by the most proximally encountered probability distribution when one exists but; (2) when no prior exists, one is instantiated by sequence onset characteristics; and (3) priors require context interruption to be updated. © 2013 Springer Science+Business Media.
