Health Wrap Episode 54 discusses Nobel 2026, brain research and healthcare access

In the 54th episode of Health Wrap by The Hindu, Ramya Kannan, Health Editor, and Zubeda Hamid, Senior Assistant Editor, discuss the 2026 Nobel Prize in Physiology or Medicine, experimental approaches to studying human brain development, and incidents from Uttar Pradesh and Meghalaya that highlight barriers to healthcare access.

The episode begins with the 2026 Nobel Prize in Physiology or Medicine, awarded jointly to Karl Deisseroth, Peter Hegemann and Georg Nagel for discoveries concerning light-gated ion channels and optogenetics. The discussion explains how optogenetics uses light-sensitive proteins to control the electrical activity of selected nerve cells. By activating or inhibiting specific neurons, researchers can investigate how neural circuits influence movement, memory, emotions and behaviour. The technique has become an important tool in neuroscience research, including studies of neurological and psychiatric disorders. However, it remains largely a research tool and is not a routine treatment for brain disorders.
