WebApr 21, 1987 · To investigate the roles individual hippocampal cell groups play in processing of spatial information for memory, we administered low-intensity electrical stimulation to the granule cells, CA3 and CA1 pyramidal cells of the dorsal hippocampus at selected times before and after acquisition of the solution to a radial maze win-stay task. WebFeb 14, 2014 · Introduction. Granule cells (GCs) in the dentate gyrus are crucial for transferring information from the entorhinal cortex to the hippocampus proper where they integrate the classical excitatory trisynaptic circuit (McBain, 2008).Although primarily glutamatergic, the axons of GCs, the mossy fibers (MFs), contain GABA, its synthesizing …
WebThe granule cells occupy a strategic location in the cerebellum, since they are the only excitatory neurons and relay information coming from the rest of the central nervous system to the entire cerebellar cortex (Fig. 31.1a).Thus, all the operations performed by the cerebellum depend on the elaboration carried out by the granular layer and retransmitted … TrkB is responsible for the maintenance of normal synaptic connectivity of the dentate granule cells. TrkB also regulates the specific morphology (biology) of the granule cells and is thus said to be important in regulating neuronal development, neuronal plasticity, learning, and the development of epilepsy. The TrkB regulation of granule cells is important in preventing memory deficits and limbic epilepsy. This is due to the fact that dentate granule cells play a critical role i…
WebThe hippocampus mediates several higher brain functions, such as learning, memory, and spatial coding. The input region of the hippocampus, the dentate gyrus, plays a critical role in these processes. Dentate gyrus granule cells receive excitatory neuron input from the entorhinal cortex and send excitatory output to the hippocampal CA3 region via the …
