| 释义 | BETA Examples of dentatedentate isn’t in the Cambridge Dictionary yet. You can help! This reduction in dentate neurogenesis is associated with elevated plasma corticosterone levels. Just adjacent to that, through the lateral dentate nucleus, passes the projection to premotor cortex. The granule cells in the dentate gyrus of the hippocampus continue to proliferate into adulthood, and neurogenesis in this region is markedly reduced by stress. Long-lasting potentiation of synaptic transmission in the dentate area of the anaesthetized rabbit following stimulation of the perforant path. Proliferation of granule cell precursors in the dentate gyrus of adult monkeys is diminished by stress. Second, elevated and synchronized neuronal activity facilitates neurogenesis in the dentate. In this context, we describe recent experiments linking adult neurogenesis to long-term synaptic plasticity in the hippocampal dentate gyrus. Proliferation of granule cell precursors in the dentate gyrus of adults monkeys is diminished by stress. The hippocampus included the dentate gyrus, the hippocampus proper, and the subicular complex. Proliferation of granule cell precursors in the dentate gyrus of adult monkeys is dimished by stress. Using field-recording techniques, we have investigated the role of adult neurogenesis in dentate hippocampal synaptic plasticity. The dentate region of the hippocampal formation can experience permanent cell loss as a result of prolonged stress. In addition, adrenal steroids also appear to contribute to increased levels of cell death and replacement in the dentate gyrus. The cerebellar projection that ultimately arrives in primary motor cortex passes through the dorsal portion of the dentate nucleus (one of the cerebellar output nuclei). Each animal received a single unilateral graft of 25 000 cells in 2 l into either the hippocampal dentate gyrus or striatum. Thus, proliferative neurogenesis in the adult dentate is important for memory consolidation. |
