SUMMARY:Dr. Trevor Robbins: The neural basis of compulsive behavior: Implications for neuropsychiatry
DESCRIPTION:Dr. Trevor Robbins from Cambridge University will be presenting: The neural basis of compulsive behavior: Implications for neuropsychiatry. \nTalk abstract: \nImpulsivity and compulsivity represent complementary cases of dysexecutive control\, of considerable relevance to psychiatry. Whilst there has been intense focus on the dimensional construct of impulsivity\, compulsivity has received far less attention. A working definition of compulsivity is of actions persisting inappropriate to the situation\, having no obvious relationship to the ultimate goal and often resulting in undesirable consequences. This definition can be dissected neuropsychologically in several ways which I will illustrate by describing behavioural\, computational and neuroimaging studies in two prototypical and devastating disorders of compulsivity\, stimulant drug addiction and obsessive-compulsive disorder (OCD). One notion is that compulsive behavior is uncontrolled and excessive habitual responding at the expense of adaptive goal-seeking behaviour. Habits are governed by stimulus-response representations that do not involve goals or rewards. These two forms of behavioural control have been characterized by studies in experimental animals and humans indicating mediation by distinct\, though interactive\, fronto-striatal systems. \nHypothetically\, addiction and OCD represent imbalance in these neural systems for goal-directed and habitual behaviour. I will examine several different ways of testing this hypothesis in stimulant drug abusers and patients with OCD and make comparisons indicating common\, as well as distinctive\, features of the two disorders. I will explore the implications of this research for causal accounts of behaviour including psychopathology\, new therapeutic approaches\, and the functional organization of fronto-striatal systems in the brain and their chemical neuromodulation. \nBio: \nTrevor Robbins was appointed in 1997 as the Professor of Cognitive Neuroscience at the University of Cambridge. He was formerly Professor of Experimental Psychology (and Head of Department) at Cambridge from October 2002-October 2017. He is also Director of the Behavioural and Clinical Neuroscience Institute (BCNI)\, jointly funded by the Medical Research Council and the Welcome Trust. The mission of the BCNI is to inter-relate basic and clinical research in psychiatry and neurology for such conditions as Parkinson’s\, Huntington’s\, and Alzheimer’s diseases\, frontal lobe injury\, schizophrenia\, depression\, drug addiction and developmental syndromes such as attention deficit/hyperactivity disorder. Trevor’s current research is focused on impulsive-compulsive disorders (such as OCD and drug addiction) and fronto-striatal systems of the brain. \nTrevor is a Fellow of the British Psychological Society (1990)\, British Pharmacological Society (2017)\, the Academy of Medical Sciences (2000) and the Royal Society (2005). He has been President of the European Behavioural Pharmacology Society (1992-1994) and he won that Society’s inaugural Distinguished Scientist Award in 2001. He was also President of the British Association of Psychopharmacology from 1996 to 1997. He has edited the journal Psychopharmacology since 1980 and joined the editorial board of Science in January 2003. He has been a member of the Medical Research Council (UK) and chaired the Neuroscience and Mental Health Board from 1995 until 1999. \nHe has been included on a list of the 100 most cited neuroscientists by ISI\, has published over 800 full papers in scientific journals and has co-edited eight books (Psychology for Medicine: The Prefrontal Cortex; Executive and Cognitive Function: Disorders of Brain and Mind 2:Drugs and the Future: The Neurobiology of Addiction; New Vistas. Decision-making\, Affect and Learning: Cognitive Search: Evolution\, Algorithms\, and the Brain; and Translational Neuropsychopharmacology). He was recently ranked as “the 4th most influential brain scientist of the modern era”. \nThis talk will be in person (Rudy North Lecture Theatre) and also via Zoom. \nZoom details: \n\nOpen https://ubc.zoom.us/ and click on ‘Join a Meeting’.\nMeeting ID: 91512 289258\nPasscode: 289258

SUMMARY:Dr. Barbara Sahakian: Good Brain Health\, Cognition and Wellbeing
DESCRIPTION:Dr. Barbara Sahakian from Cambridge University will be presenting: Good Brain Health\, Cognition and Wellbeing. \nTalk abstract: \nMany people consider their physical health and regularly exercise and wear devices to count their steps\, and to take other physiological measures. However\, to realise our potential throughout our life and to ensure a flourishing society\, it is important to focus on good brain health and wellbeing.  Environmental factors and our behaviour can improve our brains\, cognition and mental health or detract from it. Our diet\, our sleep and our social support systems are all key to improving brain health and cognition and reducing the risk of dementia. At the other end of the age spectrum\, social connectedness with friends and early reading can be beneficial for brain structure\, cognition and wellbeing in adolescence. One potential way to improve cognition is through cognitive training using games on iPads or mobile phones\, which has been shown to be beneficial for attention\, learning and memory in healthy people or patients with schizophrenia\, mild cognitive impairment (MCI) or stroke. \nBio: \nProfessor Barbara Sahakian is Professor of Clinical Neuropsychology in the Department of Psychiatry at the University of Cambridge. She is a Fellow of the British Academy and a Fellow of the Academy of Medical Sciences. She is a past president of the International Neuroethics Society and of the British Association for Psychopharmacology. According to Research.com she is one of the very top researchers worldwide in the fields of neuroscience and psychology. \nShe has over 550 publications in scientific journals\, including Science\, Nature and The Lancet. According to Google Scholar she has an h-index of 159. She has also been a leader in Government Policy on neuroscience and mental health\, including on the UK Government Foresight Project on “Mental Capital and Wellbeing” and has spoken in Davos at the World Economic Forum in 2014. \nShe has co-authored two popular science books published by Oxford University Press “Bad Moves: How Decision Making Goes Wrong and the Ethics of Smart Drugs” and “Sex\, Lies & Brain Scans”. “Sex\, Lies & Brain Scans” won the British Psychological Society Popular Book Award. She regularly writes for The Conversation. \nShe is co-Inventor of the Cambridge Cognition CANTAB computerized cognitive tests which are used around the world and the PEAK Wizard Memory Game and Decoder Attention and Concentration Game. She is also co-inventor of the EMOTICOM computerized tests of social and emotional cognition. \nProfessor Sahakian holds PhD and DSc degrees from the University of Cambridge. She is also a Clinical Psychologist. She is a Fellow of Clare Hall\, Cambridge. \nThis talk will be in person (Rudy North Lecture Theatre) and also via Zoom. \nZoom details: \n\nOpen https://ubc.zoom.us/ and click on ‘Join a Meeting’.\nMeeting ID: 91067 093313\nPasscode: 093313
