Few neurons, including the stellate and basket cells, were located in this layer.
The current study examined the numbers of synapses in the molecular layer, where the large majority synapses between the dendritic spines of Purkinje cells and climbing fibres, parallel fibres, and interneurons (stellate and basket cells) had been found.
Incoming glutamatergic perforant path fibers form excitatory synapses on both the principal glutamatergic granule cells and neighboring GABAergic interneurons, for example, basket cells
Three main types of perisomatic interneurons can be distinguished in the human hippocampus: parvalbumin(PV-) positive axo-axonic or chandelier cells, PV-positive basket cells
, and Type 1 cannabinoid receptor- (CB1-) positive basket cells
also containing cholecystokinin .
Joining shrub cells are the freshly named horizontally elongated cells, deep-projecting cells, L5 basket cells
and L5 neurogliaform cells.
Among these, inhibitory neurons, Purkinje cells, Golgi cells, stellate cells and basket cells
are generated at the VZ of the cerebellar primordium.
In the granular layer of the cerebellar cortex we showed bands of tissue rarefaction and a drastic reduction in the number of basket cells
. The remained cells were unevenly located at different layers.
The inhibitory modulation in the intracortical circuit comes from other type of cells including Golgi (Neuron stellatum magnum), basket cells
and stellate cells (Watson et al.; Waxman).
