  1. Excitatory postsynaptic potential - Wikipedia

    In neuroscience, an excitatory postsynaptic potential (EPSP) is a postsynaptic potential that makes the postsynaptic neuron more likely to fire an action potential.

  2. Postsynaptic potentials: EPSPs and IPSPs | Kenhub

    Nov 21, 2024 · 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 …

  3. Postsynaptic Potentials – Foundations of Neuroscience

    An excitatory postsynaptic potential (EPSP) occurs when sodium channels open in response to a stimulus. The electrochemical gradient drives sodium to rush into the cell.

  4. Excitatory and Inhibitory Postsynaptic Potentials

    PSPs are called excitatory (or EPSPs) if they increase the likelihood of a postsynaptic action potential occurring, and inhibitory (or IPSPs) if they decrease this likelihood.

  5. EPSP vs. IPSP - What's the Difference? | This vs. That

    EPSPs are depolarizing events that increase the likelihood of the postsynaptic neuron firing an action potential, while IPSPs are hyperpolarizing events that decrease the likelihood of firing an action …

  6. What Is an Excitatory Postsynaptic Potential? - Biology Insights

    Jul 24, 2025 · An excitatory postsynaptic potential, or EPSP, represents a temporary shift in the electrical charge across a neuron’s membrane. This change makes the receiving neuron more likely …

  7. Excitatory Postsynaptic Potential - an overview - ScienceDirect

    Postsynaptic potentials are graded potentials in the postsynaptic membrane resulting from the effects of a neurotransmitter. An excitatory postsynaptic potential (EPSP) is a graded depolarization caused by …

  8. 10.5G: Postsynaptic Potentials and Their Integration at the Synapse

    Excitatory postsynaptic potentials (EPSP) bring the neuron’s potential closer to its firing threshold. Inhibitory postsynaptic potentials (IPSP) change the charge across the membrane to be further from …

  9. CNS Tech Lab - Boston University

    An excitatory postsynaptic potentials (EPSP) is a temporary depolarization of postsynaptic membrane caused by the flow of positively charged ions into the postsynaptic cell as a result of opening of …

  10. Graded Potentials – Introduction to Neurobiology

    An excitatory postsynaptic potential (EPSP) occurs when sodium channels open in response to a stimulus. The electrochemical gradient drives sodium to rush into the cell.
