Postsynaptic potential - Wikipedia
Postsynaptic potentials are changes in the membrane potential of the postsynaptic terminal of a chemical synapse. Postsynaptic potentials are graded potentials, and should not be confused with action potentials although their function is to initiate or inhibit action potentials.
Postsynaptic Potentials – Foundations of Neuroscience
Postsynaptic potentials are changes in membrane potential that move the cell away from its resting state. For our purposes, postsynaptic potentials are measured in the dendrites and cell bodies. Ion channels that are opened by a stimulus allow brief ion flow across the membrane.

2024年8月21日 · Postsynaptic potentials refer to changes observed in the resting potential of the neuronal cell membrane triggered by synaptic activation. In its resting state, the cell membrane maintains a polarized potential, with the inner surface negatively charged.

2022年10月10日 · Postsynaptic potentials are changes in membrane potential that move the cell away from its resting state. For our purposes, postsynaptic potentials are measured in the dendrites and cell bodies. Ion channels that are opened by …
Postsynaptic Neuron - (Anatomy and Physiology I) - Fiveable
A postsynaptic neuron is the receiving neuron at a chemical synapse, where it integrates the signals transmitted from the presynaptic neuron. It plays a crucial role in the communication between neurons, which is essential for the nervous system's ability to perceive and respond to …
Postsynaptic potential (PSP) | Britannica
postsynaptic potential (PSP), a temporary change in the electric polarization of the membrane of a nerve cell (neuron). The result of chemical transmission of a nerve impulse at the synapse (neuronal junction), the postsynaptic potential can lead to the firing of a new impulse.
Electrical Activity in Neurons – Introduction to Neuroscience
Postsynaptic potentials (also called graded potentials) are changes in membrane potential that move the cell away from its resting state. For our purposes, postsynaptic potentials are measured in the dendrites and cell bodies. Ion channels that are opened by a stimulus allow brief ion flow across the membrane.
Postsynaptic Potentials – Introduction to Neuroscience
When anions flow out of a neuron through a chloride channel, the cell is depolarized. The small change in voltage (depolarization or hyperpolarization) that occurs as a result of synaptic action is called the postsynaptic potential.

2023年10月31日 · First, reuptake by astrocytes or presynaptic terminal where the neurotransmitter is stored or destroyed by enzymes. Second, degradation by enzymes in the synaptic cleft such as acetylcholinesterase. Third, diffusion of the neurotransmitter as it moves away from the synapse.
