The number of c-fosstained cells in V1 was increased in the supragranular layers, but not in the infragranular layers. These data suggest that a CHL causes an increase in neuronal activity at the neuronal level in the upper cortical layers of V1.
Our results expose the quantitative distribution of PV+ neurons observed in the supragranular and infragranular layers of the somatosensory cortex.
Infragranular layers had approximately 55% more PV+ neurons than supragranular layers (Fig.3).
It is important to point out that the onset of PV expression appears by postnatal day 8 in the infragranular layers and three days later in the supragranular layers of the neocortex (Alcantara et al., 1993).
