The paper tracks and manipulates striatal neuron activity during goal-directed learning and habit formation, finding D1+ neurons maintain stable action representations while A2A+ neurons show transient or slow reorganization.

This study shows that hippocampal place cell remapping occurs when rats remember aversive shocks but not when they forget them or encounter neutral stimuli.

The paper introduces a miniature microscope for high-resolution neural imaging in freely behaving rats, capable of imaging over 1000 neurons in the hippocampus and 2000 in the cortex.

DeCalciOn is a hardware system for real-time decoding of in vivo calcium imaging data, enabling closed-loop feedback experiments with millisecond latency.

This study uses chemogenetics and calcium imaging in rats to show that anterior cingulate cortex (ACC) discriminates between reward options, influencing effort-based decisions.
