AbstractThe brain helps us survive by forming internal representations of the external world1,2. Excitatory cortical neurons are often precisely tuned to specific external stimuli3,4. However, inhibitory neurons, such as parvalbumin-positive (PV) interneurons, are generally less selective5. PV interneurons differ from excitatory neurons in their neurotransmitter receptor subtypes, including AMPA (α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid) receptors (AMPARs)6,7.

MATERIALS AND METHODSMarmosetsMarmosets were pair-housed in spacious holding rooms with environmental control of temperature (23° to 28°C), humidity (40 to 72%), and 12-hour light/dark cycle. Their cages were equipped with a variety of perches and enrichment devices, and they received regular health checks and behavioral assessment from Massachusetts Institute of Technology (MIT) Division of Comparative Medicine (DCM) veterinary staff and researchers.
