About this Lecture


In this lecture, we think about biological rhythms, focusing in particular on: (i) endogenous pacemakers, which utilise our internal ‘clock’ to regulate behaviours like our sleep-wake cycle; (ii) exogenous zeitgebers, which utilise external factors like sunlight to regulate behaviours; (iii) the negative impact that shift work and crossing time zones can have on our health and wellbeing.


In this course, Dr Ashok Jansari (Goldsmiths, University of London) explores the layout and function of the brain from a biopsychological perspective. In the first lecture, we think about how the nervous system transcodes sensory input into electrical signals that can be processed in the brain. In the second lecture, we think about how different areas of the brain are specialised to perform certain functions, and some of the early research which led to these discoveries. In the third lecture, we think about the different techniques used to generate images of brain structure and activity. Next, we think about how internal and external cues can influence our biological rhythms. In the fifth and final lecture, we think about the role of longitudinal research and brain imaging in understanding how behaviour consistency and change can be represented by physical brain structure differences, contextualised in a study on delayed gratification.


Dr Ashok Jansari is a senior lecturer in the Department of Psychology at Goldsmiths, University of London. Dr Jansari’s research interests include memory disorders, prosopagnosia, executive functions, and synaesthesia. Dr Jansari is most famous for his research into prosopagnosia, having made numerous TV appearances, including on BBC1’s The One Show, as well as hosting his own ‘Neuro Talk’ YouTube channel:

Some of Dr Jansari's recent publications include 'Acquired synaesthesia following 2C-B use' (2019), 'Using virtual reality to investigate multitasking ability in individuals with frontal lobe lesions' (2019), and 'Identification from CCTV: Assessing police super-recogniser ability to spot faces in a crown and susceptibility to change blindness' (2018).
