Biological Psychology (PSYC20006)

This subject studies the relationship between brain mechanisms and behaviour. Its major aim is to develop an appreciation of the neurobiological basis of psychological function and dysfunction via two approaches. The first emphasises a top-down method that links psychological functions to their biological substrates. Neuroscientific research techniques and what they can reveal about psychological function are emphasised. These techniques are presented within an historical context, beginning with transcranial magnetic stimulation (TMS), continuing with electroencephalography (EEG) and functional magnetic resonance imaging (fMRI), and finishing with modern molecular genetic techniques. The second approach emphasises a bottom-up approach including the topics of brain genetics and development, neurons and neural circuits, neurotransmission and neurotransmitter substances, and the structurofunctional properties of selected brain regions. Neurobiological principles are illustrated using conditions with abnormal neuronal function. The third approach combines the top-down and bottom-up approaches to demonstrate how combining knowledge of cognitive theory and structurofunctional properties of the brain enables diagnosis and interpretation of pathological conditions. Case studies are used to illustrate this approach.

A quantitative methods component will be integrated into the lecture, tutorial and assessment structure of this subject. The aim is to provide an understanding of, and practical experience with, the appropriate experimental design and statistical analysis techniques used to evaluate hypotheses in Biological Psychology.
