About Program







This is part of its efforts to popularize science to the general public and students who are pursuing science as their career. TNSF attempt to focus on students on higher science as everyone knows that learning of science at college within the curriculum is not enough to acquire holistic knowledge of science at the appropriate time. Hence, to fill the gap between what students are acquiring through the curriculum and what it is required, TNSF is planning its activities on higher science to students who are pursuing higher education.




About the Lecture
Almost everything we do – how we react to circumstances, how we behave, and how we interact with the people around us – are influenced by our emotions. How emotions and internal motivations influence our reactivity to external cues, and in turn how they drive our behaviours are fundamental questions that need answering using simple systems. How did emotions evolve? What functions do they serve? Importantly, how can we use the genetic and molecular tools available in invertebrates like Drosophila, zebrafish and C. elegans to dissect the neural circuitry and molecular mechanisms of emotions and internal states? These are some of the questions I will explore in the talk. My hope is that the audience can take home a workable definition of emotion, can appreciate how primitive states in “simpler” animals like flies and worms can be used to ask bigger questions about emotions and motivated behaviours, and can appreciate the need to answer these fundamental questions towards our collective human quest to understand how the brain works.

Sheetal Potdar

Sheetal Potdar, PhD

Sheetal Potdar, PhD is a neuroscientist by training and a science communicator by profession. From an early age, she has been fascinated by how the brain drives behaviour and shapes our personality.
Her research journey began with a summer internship where she learned about evolution, ecology, and animal behaviour. There she became intrigued by circadian clocks – the 24-hour timekeeping systems that govern our activity and rest. She pursued a Master’s degree at JNCASR, Bengaluru, studying how circadian clock neurons maintain behavioural rhythms across seasons in fruit flies Drosophila melanogaster.
For her PhD, she investigated the neural circuits that regulate sleep and wakefulness, examining how neurons that control how long flies sleep interact with circadian neurons that determine when they sleep. Later, as a postdoctoral fellow at the Salk Institute in San Diego, she studied how hunger influences aggression in Drosophila and identified neurons that make flies aggressive, but only when they are hungry.
Now based in Belagavi, India, she focuses on communicating science to wider audiences through writing and storytelling for newspapers and magazines.
