This study shows that serotonin release from the dorsal raphe nuclei to the orbitofrontal cortex enhances reversal learning by increasing neuronal excitability and synaptic plasticity.

This paper introduces ST-Cal-Light, a method to tag active neurons by converting somatic calcium signals into gene expression, enabling precise functional circuit analysis.

This study shows that Kv1.2 regulates hippocampal CA3 neuronal ensemble size and plasticity, contributing to pattern separation by preventing excessive synaptic changes.
