How do animals stay precise when their whole brain heats up or cools down? Larval zebrafish hunt accurately across a 10°C range. What enables such stability? What mechanism might support it? #zebrafish #neuroscience #temperature @STishbyTamari @ELSCbrain

We identified a brain-wide neural signature that preceded social actions. This signature predicts both the type of upcoming action and individual differences in social behavior.

A brief summary of our preprint: We developed a new assay that allows whole-brain neural recording in a fish as it observes and responds to a conspecific (1/4)

Excited to share! Whole-brain imaging during real-time social interaction uncovers a neural signature predicting social actions and individual differences. #SocialNeuroscience #SocialBehavior #Zebrafish @ImriLifshitz @ELSCbrain

Social behavior is essential for animal survival and adaptation, requiring the integration of sensory cues to guide interactions with conspecifics. A key component of social behavior is approach,...

We demonstrate that this outcome repertoire forms a two-dimensional manifold and propose hypotheses regarding the motor control of the respective movements.

This movement principle uncovered that fish close the entire angle to the target prey in each movement and therefore decouple turn and distance decisions while hunting.

This description of the repertoire uncovered principles of fish movement, where fish rotate around a point, which we identified, and move forward or backward on a straight line.

We show that the change in heading angle and the change in position following a movement are coupled. We mathematically captured this relation.

Rather than studying the complex (tail and fins) movements, we focused on their outcome, i.e. the change in position and orientation following a movement.

The behavioral repertoire of the larval zebrafish is known to be high dimensional and complex.

In goal-directed behavior animals select actions from a diverse repertoire of possible movements. Accurately quantifying the complete behavioral repertoire can uncover the underlying rules that guide...

Does spontaneous activity in sensory cortices contribute to neural coding? Carsen Stringer @computingnature & @LilachAvitan cover recent work in various developing and mature animals, and map out new roles for spontaneous activity in this #Perspective: https://t.co/v3D68C8cOc

Avitan and Stringer cover recent work describing large-scale spontaneous activity in developing and mature animals. They show that spontaneous activity is high dimensional, correlated with behavior,...

Recently revealed properties of spontaneous activity in sensory areas suggest a new functional role. What is this activity for? We looked across species and development for answers with @computingnature in @NeuroCellPress 🐭🐟🤠🪰: https://t.co/tdtaHAU86J

Bam! And where is that hopping larva gif? We demand the gif!
Extremely excited and honoured to be named as one of 2021 Allen Distinguished Investigators. Together with @SGRodriques we will develop new connectomics methods and use them to figure out how jumping behaviour evolved in fly larvae. We are recruiting so DM if interested!
