ARC Technical (Christmas) Social | Wed Dec 14 2022 | Asaph Zylbertal - UCL

Science & Technology

Join us to (festively) hear Dr. Asapy Zylbertal discuss the technical challenges of using AI to predict zebrafish brain state and behaviour

The New Years special edition of Tech Socials presents

Using AI to predict zebrafish brain state and behaviour from whole-brain cellular-resolution functional imaging

Abstract

Behavioural responses vary across presentations of identical sensory stimuli, in part owing to long-term changes in internal state variables such as motivation and stress. Some of these state variables are represented by ongoing neuronal activity, persisting in the absence of sensory input and often involving complex patterns across multiple brain areas. I study how ongoing activity in the larval zebrafish brain is associated with the execution of innate visually-evoked behaviour. I simultaneously track the activity of 100,000 neurons using light-sheet microscopy, a method that enables high-speed volumetric imaging of the entire zebrafish brain in vivo. To identify patterns associated with specific behavioural features, I train artificial recurrent neural networks to predict behavioural outcomes from activity recorded prior to prey-like visual stimulus presentations.

I will discuss some of the technical challenges I'm facing, related to elaborate online control, dealing with immense data volumes, and complicated model interpretation.

Speaker

Asaph is a Postdoctoral Researcher in Dr Isaac Bianco's lab, based in the Department of Neuroscience, Physiology and Pharmacology at UCL. He is studying how internal state and network dynamics shape behaviour, by combining in vivo experimental approaches in larval zebrafish and computational modelling.

Asaph studied Biology for his BSc at the Hebrew University of Jerusalem, and stayed there for his MSc and PhD in neuroscience.
