Circuit inhibition promotes the dynamic reorganization of prefrontal task encoding to support cognitive flexibility
The mammalian prefrontal cortex encodes variables related to goal-directed behavior, and enables flexibility during environmental changes, making it critical to understand how the dynamic updating vs....

Prefrontal gamma oscillations engage dynamic cell type-specific configurations to support flexible behavior
Cognitive dysfunction in conditions such as schizophrenia involves disrupted communication between the prefrontal cortex (PFC) and mediodorsal thalamus (MD). Parvalbumin interneurons (PVI) are known t...

Context-invariant socioemotional encoding by prefrontal ensembles - Nature Communications
How the ensemble encoding of social and anxiety-related behaviors interacts with encoding of context in the prefrontal cortex of mice is not fully understood. Here authors examine how prefrontal neurons encode socioemotional behaviors in different contexts and reveal that the prefrontal cortex encodes context-invariant representations of these behaviors in parallel with representations of context.

Synaptic plasticity of prefrontal long-range inhibition regulates cognitive flexibility
While glutamatergic synaptic plasticity is believed to be a fundamental mechanism mediating learning, the behavioral significance of plasticity at cortical GABAergic synapses remains less well underst...

Loss of the autism associated gene Tbr1 disrupts prediction and encoding by prefrontal ensembles during socioemotional behaviors
Disruptions in many genes linked to autism spectrum disorder (ASD) affect synaptic function and socioemotional behaviors in mice. However, exactly how synaptic dysfunction alters neural activity patte...
