WebThe release of excitatory and inhibitory neurotransmitters by these fibers activates specific postsynaptic receptors and generates excitatory and inhibitory postsynaptic potentials, respectively. By electrotonic spread of postsynaptic potentials along the apical dendrites and equivalent capacitive currents, they become electrical dipoles. Web15 Feb 2024 · The postsynaptic receptors allow the transmission of positively or negatively charged ions into another neuron or cell. At rest, a neuron is negatively charged. The post-synaptic action...
Difference Between Action Potential and Synaptic Potential
WebThe synaptic cleft is the name for the tiny space that exists between the membrane of the postsynaptic cell and the axon terminal of the presynaptic neuron. Voltage-gated calcium channels in the cell membrane are opened when an action potential, or nerve impulse, reaches the axon terminal. Ca 2+ rushes into the cell, where it is located in much ... Web2) Electrical:-The electrical current generated by the AP is transmitted directly to the post synaptic cell by electrical coupling because the two cells are in tight contact with each other (gap junctions).-This is fast and reliable. This type of transmission occurs in some retinal cells and in cardiac cells. Also occurs between some glial cells e.g. astrocytes. The major … breech\\u0027s dj
