Layer-specific serotonergic facilitation of IPSC in layer 2/3 pyramidal neurons of the visual cortex.

abstract：:The relative motion between the surface of an object and our fingers produces patterns of skin deformation such as stretch, indentation, and vibrations. In this study, we hypothesized that motion-induced vibrations are combined with other tactile cues for the discrimination of tactile speed. Specifically, we hypothesi...
