Main references (data with "?" refer to a reasonable guess; with
"??" to a total guess):
Morphology: Same as polymorphic cells?!
Number and connectivity: Bernard and Wheal,
1994.
Biochemistry and physiology: Freund and Buzsaki,
1996.
Type: Interneurons, inhibitory (GABA)
Number: 4000
Location (CA3): Soma and axon in stratum radiatum, dendrites
in all layers.
Explicit morphological data: Southampton archive (cells l18, l82 etc.)
Notes: These interneurons are assumed to be dendro-specific basket
cells.
Connectivity:

specified; in parenthesis: number of cells of that type):

800 CA3 oi (4000)
200 CA3 cc (1000)
Axo-somatic input:
GABA ?550 SHP on soma and dendrites (climbing)
Dendritic input:
