WebNeural Transmission. The function of a neuron is to transmit information within the nervous system. Neural transmission occurs when a neuron is activated, or fired (sends out an electrical impulse). Activation (firing) of the neuron takes place when the neuron is stimulated by pressure, heat, light, or chemical information from other cells. WebMembrane depolarization triggers a calcium influx and activates a complex signaling cascade with highly dynamic gene expression [27,28]. In this study, we took advantage of such an ideal system to investigate the dynamics of m 5 C modification in neurons in response to environmental stimuli and explore the correlation between the changes in ...

Above a certain threshold, voltage-gated ion channels in the membrane are opened and an influx of (usually) sodium ions into the cell occurs. This process leads to initiation of action potential and the neuron is firing. farm burger peachtree corners
