Figure 6.
Neuron and interneuron density in the posterior cingulate cortex. There was no significant difference in the density of thionin stained neurons in the PCC (a). There was a trend towards a reduced density of calbindin positive neurons (b) in the superficial and deep layers in the autism group, with no change in the percentage of calbindin neurons (c). There was no change in the density (d) or percentage (e) of parvalbumin neurons in the PCC. Each symbol represents an individual case.
