Auditory cortical PV+ neurons were well tuned for frequency, although very tightly tuned PV+ cells were uncommon.

we found that auditory cortical PV+ neurons were well tuned for frequency, although very tightly tuned PV+ cells were uncommon
PV+ interneurons had shallower response gain and were less intensity-tuned than PV- neurons.
Quoted textsource-backed
PV+ interneurons had shallower response gain and were less intensity-tuned than PV- neurons
PV+ neurons had markedly faster response latencies than PV- neurons.
Quoted textsource-backed
PV+ neurons also had markedly faster response latencies than PV- neurons
Faster PV+ response latencies are consistent with a computational role in enhancing the temporal precision of cortical responses.

PV+ neurons likely play a minor role in shaping frequency tuning and may nonselectively pool input from the local network.
Quoted textsource-backed
This suggests that PV+ neurons play a minor role in shaping frequency tuning, and is consistent with the idea that PV+ neurons nonselectively pool input from the local network.
PV+ neurons may provide dynamic gain control and shape intensity tuning in auditory cortex.
