Dr. Joseph Valentino Raimondo MBChB (Cape Town) MSc (Oxford) DPhil Neuroscience (Oxford)

Neurophysiology Research Group

Joseph Raimondo

Senior lecturer, Division of Cell Biology, Department of Human Biology, Faculty of Health Sciences, UCT & Associate Member of the Institute of Infectious Disease and Molecular Medicine (IDM) and the Neuroscience Institute (NI)

Joseph Raimondo is a neuroscientist who investigates brain function and dysfunction using electrophysiological, optical imaging and computational approaches. His career ambition is to produce outstanding research of both local and global relevance, whilst developing African capacity in cellular neurophysiology and computational neuroscience. The primary aim of his research group is to answer the question: ‘Why do brains seize?’

The lab attempts to answer this question by examining the cellular and circuit level interactions between brain cells, which result in the development of epileptic seizures. They have a focus on how changes to inhibitory synaptic transmission and neuroinflammatory responses relate to the emergence and termination of epileptic seizures.

Key areas of expertise: Neurophysiology , epilepsy, synaptic transmission, plasticity, neurocysticercosis, patch-clamp electrophysiology, optical imaging, neuronal biophysics
