WebbWhile the remap index value for granule cells was similar to that of mossy cells for the different shape condition, the remap index value of granule cells was lower than that of mossy cells for same shape condition (different shape GC: 0.57; MC: 0.54; same shape GC: 0.21; MC: 0.43) ( Figures 3 G and 3H). To estimate the distribution for each ... Webb1. Whole-cell patch-clamp recordings of excitatory postsynaptic currents (EPSCs) were built from guinea pig hippocampal CA1 pyramidal mobile.

Natural spike patterns also cause long-term potentiation of NMDA receptor-mediated synaptic transmission that overrides the effects of KAR LTD on the cellular response to low-frequency synaptic input.

WebbIn additions, cells in the supramammillary region, an area not previously recognized to project to the hippocampus, were labeled. Finally, the mossy fiber terminal zone and … WebbAbstract One peculiarity of the hippocampal CA3 mossy fiber terminals is the co-release of zinc and glutamate upon synaptic transmission. How these two players act on hippocampal-dependent memories is still unclear. To decipher their respective involvement in memory consolidation, a pharmacological approach was chosen.
