Altered patterning of
dentate granule cell mossy fiber inputs onto CA3 pyramidal cells in limbic epilepsy.
Not exact matches
Overstreet - Wadiche and UAB colleagues posed a basic question: Since the number of neurons in the
dentate gyrus increases by neurogenesis while the number of neurons in the cortex remains the same, does the brain create additional synapses from the cortical neurons to the new
granule cells, or do some cortical neurons transfer their connections from mature
granule cells to the new
granule cells?
In agreement with predictions from these models, we show that minimal changes in the shape of the environment in which rats are exploring can substantially alter correlated activity patterns among place - modulated
granule cells in the
dentate gyrus.
When a new
granule cell neuron is made in the
dentate gyrus, it needs to get «wired in,» by forming synapses, or connections, in order to contribute to circuit function.
We have tested this hypothesis by generating and analyzing a mouse strain that lacks the gene encoding the essential subunit of the N - methyl - d - aspartate (NMDA) receptor NR1, specifically in
dentate gyrus
granule cells.
These results provide evidence that NMDA receptors in the
granule cells of the
dentate gyrus play a crucial role in the process of pattern separation.

dentate, spine density is significantly decreased on dendrites of
