  2. Inhibitory postsynaptic potential - Wikipedia

    en.wikipedia.org/wiki/Inhibitory_postsynaptic...

    The size of the neuron can also affect the inhibitory postsynaptic potential. Simple temporal summation of postsynaptic potentials occurs in smaller neurons, whereas in larger neurons larger numbers of synapses and ionotropic receptors as well as a longer distance from the synapse to the soma enables the prolongation of interactions between neurons.

  3. Synaptic potential - Wikipedia

    en.wikipedia.org/wiki/Synaptic_potential

    A synaptic potential may get stronger or weaker over time, depending on a few factors. The quantity of neurotransmitters released can play a large role in the future strength of that synapse's potential. Additionally, the receptors on the post-synaptic side also play a role, both in their numbers, composition, and physical orientation.

  4. Apical dendrite - Wikipedia

    en.wikipedia.org/wiki/Apical_dendrite

    The inhibitory system, by contrast, possess several (10) different types of synapses originating from specifically differentiated cells and are much more difficult to track. [9] There is insufficient information to precisely distinguish between excitatory and inhibitory pathways contributing to the alterations in neurotransmitter expression and ...

  5. Postsynaptic potential - Wikipedia

    en.wikipedia.org/wiki/Postsynaptic_potential

    If the cell is receiving both inhibitory and excitatory postsynaptic potentials, they can cancel each other out, or one can be stronger than the other, and the membrane potential will change by the difference between them. Temporal summation: When a single synapse inputs that are close together in time, their potentials are also added together ...

  6. Synapse - Wikipedia

    en.wikipedia.org/wiki/Synapse

    In many synapses, the presynaptic part is located on the terminals of axons and the postsynaptic part is located on a dendrite or soma. Astrocytes also exchange information with the synaptic neurons, responding to synaptic activity and, in turn, regulating neurotransmission . [ 10 ]

  7. Basket cell - Wikipedia

    en.wikipedia.org/wiki/Basket_cell

    Basket cells are multipolar GABAergic interneurons that function to make inhibitory synapses and control the overall potentials of target cells. In general, dendrites of basket cells are free branching, contain smooth spines, and extend from 3 to 9 mm. Axons are highly branched, ranging in total from 20 to 50mm in total length.

  8. Calyx of Held - Wikipedia

    en.wikipedia.org/wiki/Calyx_of_held

    This synapse has been described as the largest in the brain. [10] The related endbulb of Held is also a large axon terminal synapse (15–30 μm in diameter) found in another auditory brainstem structure, namely the anteroventral cochlear nucleus (AVCN). [11] As with the calyces, these synapses promote fast, efficient information transfer.

  9. Stellate cell - Wikipedia

    en.wikipedia.org/wiki/Stellate_cell

    Stellate cells are neurons in the central nervous system, named for their star-like shape formed by dendritic processes radiating from the cell body. These cells play significant roles in various brain functions, including inhibition in the cerebellum and excitation in the cortex, and are involved in synaptic plasticity and neurovascular coupling.
