Approximately 15–20% of neurons in the mammalian neocortex release gamma-aminobutyric acid (GABA) as their primary neurotransmitter, and these inhibitory interneurons shape virtually every aspect of cortical computation — from the millisecond timing of action potentials to the modulation of network oscillations across behavioral states [Rudy2011] [Kepecs2014].

Models are evaluated for their ability to generate insight and organize data, but the field’s persistent gap between model prediction and experimental validation is treated as an open problem, not a settled methodology ^{1Citationpaper:34a07597-2d6f-4552-b9cf-d2d11817f9f9Cortical circuits depend on inhibition.
