A global dopaminergic learning rate enables adaptive foraging across many options

This study develops a reinforcement learning model to understand how mice adaptively forage across multiple options, finding that dopamine in the nucleus accumbens core reflects a global learning rate.

Low-latency extracellular spike assignment for high-density electrodes at single-neuron resolution

This paper develops a low-latency system for assigning single-neuron identities from neural signals, enabling real-time applications in brain-machine interfaces.

Serotonergic neurons mediate operant conditioning in Drosophila larvae

This study demonstrates operant conditioning in Drosophila larvae by optogenetically activating serotonergic neurons and shows the ventral nerve cord's role in memory formation.
