Article Synopsis
- The primary sensory cortex, traditionally seen as a straightforward processor of sensory information, shows sparsely active neurons even during stimulation and is influenced by various factors, including context and reward.!* -
- A new study reveals that reinforcement learning transforms neuron activity in the superficial layers of the mouse primary somatosensory cortex, activating previously inactive neurons and expanding touch sensitivity related to behavioral choices.!* -
- Findings suggest that these cortical layers exhibit significant learning-dependent changes and are shaped by non-sensory elements such as timing and unexpected events, indicating a complex role beyond simple sensory processing.!*
Dysfunction of the orbitofrontal cortex (OFC) impairs the ability of individuals to flexibly adapt behavior to changing stimulus-reward (S-R) contingencies. Impaired flexibility also results from interventions that alter serotonin (5-HT) and dopamine (DA) transmission in the OFC and dorsomedial striatum (DMS). However, it is unclear whether similar mechanisms underpin naturally occurring variations in behavioral flexibility.
