Webb1 nov. 2003 · Synaptic plasticity is not the exclusive mode of regulation of information processing in the brain, and persistent regulations of ionic conductances in some specialized neuronal areas such as the dendrites, the cell body, and the axon could also modulate, in the long-term, the propagation of neuronal information. Webb13 apr. 2024 · Neuronal plasticity is critical for the maintenance and modulation of brain activity. Emerging evidence indicates that glial cells actively shape neuroplasticity, allowing for highly flexible regulation of synaptic transmission, neuronal excitability, and network synchronization. Astrocytes regulate synaptogenesis, stabilize synaptic connectivity, and …

Webb11 apr. 2024 · Interestingly, knock down of the highly abundant M1 ACh receptor in V1 failed to phenocopy the effects of decreased BF ACh activity on intrinsic excitability, suggesting either that BF ACh activity acts through a different receptor within V1, or acts indirectly via other brain regions or cell types. Webb28 nov. 2024 · We compared functional plasticity of granule cell neurons (GCNs) in the dentate gyrus (DG) of the hippocampus in concert with biochemical measures of neuronal excitability and inhibition, developmental stages of newly born GCNs, and neuroimmune responses in the DG in male and female rats immediately following context-driven … knight beam bl46-132r

WebbMeCP2-deficient PV cells exhibit high intrinsic excitability, selectively reduced efficacy of recurrent excitatory synapses in V1 layer 4 circuits, and decreased evoked visual responses in vivo. Enhancing cortical gamma-aminobutyric acid (GABA) inhibition with diazepam infusion can restore critical period plasticity in both young and adult PV-Mecp2(-/y) mice.
