Granule Cell
(B)
#
Characterized by just having a few dendrites and one axon, called the Mossy Fiber.
- Found in:
- The cerebellar cotex’s granular layer
- Input from Mossy Fibers (of the pontine nuclei/pons). Projects through the Purkinje layer into the molecular layer, then connects to dendrites of Purkinje Cell, forming the image shown above depicting ‘Gcpc synapses’.
- It requires input from many mossy fibers, which receive much more gross sensory input.
- Glutamatergic. Excites purkinje cells, but also inhibits them by exciting GABAergic interneurons.
- Input from Mossy Fibers (of the pontine nuclei/pons). Projects through the Purkinje layer into the molecular layer, then connects to dendrites of Purkinje Cell, forming the image shown above depicting ‘Gcpc synapses’.
- Dentate Gyrus
- Olfactory Bulb
- GABAergic, axonless.
- Cerebral Cortex.
