Prefrontal gamma oscillations engage dynamic cell-type-specific configurations to support flexible behavior.

Prefrontal gamma oscillations involve diverse, cell-type-specific configurations that dynamically support flexible behavior in mice.

• Why it matters: Understanding the nature and functions of gamma oscillations is crucial because their disruption is linked to cognitive deficits in conditions like schizophrenia, yet their specific circuit mechanisms remain unclear.
• What they did: Using dual-color voltage indicators and optogenetics in mice, the study identified that parvalbumin interneurons synchronize with mediodorsal thalamus-projecting prefrontal cortex neurons, creating multiple circuit-specific gamma patterns recruited during behavior.
• The result: These findings suggest gamma oscillations are composed of diverse, cell-type-specific motifs that are dynamically engaged for particular cognitive functions, offering insights into potential therapeutic targets.
