Mossy Cells (mc)

Main references (data with "?" refer to a reasonable guess; with "??" to a total guess):
Morphology: Assumed the same as for gabaergic polymorphic cells ?!
Number and connectivity: Patton and McNaughton, 1994.
Biochemistry and physiology: ??

Type: Interneurons, excitatory (glutamate).
Number: 30,000
Location (Dentate Gyruys): soma and dendrites in hilus, axon in molecular layer.

Explicit morphological data: Not available and hard to obtain because mc are polymorphic! However, see the note under morphological references.

Notes: Mossy cells provide positive feed-back to granule cells (!).


Axonal output (number of cells contacted, with one synapse unless specified; in parenthesis: number of cells of that type):
36,000 DG gc (1,000,000)
333 DG bc (10,000)
33 DG cc (1000)
1500 DG gpc (15,000)
333 DG mopp (10,000)

Axo-somatic input:
GABA 100 DG gpc (15,000) on soma
GABA 6 DG cc x8 (1000) on axon

Dendritic input:
Glu 800 DG gc (1,000,000) on shaft?
Glu 160 EC (200,000) on shaft?

Dendrites:AMPA, CCa, ?
Soma: GABA-A, GABA-B, CNa, CK?, ED, ?
Axon: GABA-A, GABA-B, CNa, CK?, EP, EC.
