  2. Pyramidal cell - Wikipedia

    en.wikipedia.org/wiki/Pyramidal_cell

    Pyramidal cells in rats have been shown to undergo many rapid changes during early postnatal life. Between postnatal days 3 and 21, pyramidal cells have been shown to double the size of the soma, increase the length of the apical dendrite fivefold, and increase basal dendrite length thirteen-fold.

  3. Sholl analysis - Wikipedia

    en.wikipedia.org/wiki/Sholl_analysis

    Sholl analysis is a method of quantitative analysis commonly used in neuronal studies to characterize the morphological characteristics of an imaged neuron, first used to describe the differences in the visual and motor cortices of cats in the early 1950s. [1]

  4. Hippocampal subfields - Wikipedia

    en.wikipedia.org/wiki/Hippocampal_subfields

    The pyramidal cells in CA3 have a unique type of dendritic spine called a thorny excrescence or thorn, only found in CA3 pyramidal cells and hilar mossy cells. The thorn has a thin single spine with a number of heads. Clusters of thorns sit on a dendrite on a broad stem.

  5. Hippocampus anatomy - Wikipedia

    en.wikipedia.org/wiki/Hippocampus_anatomy

    There is also a distinct pathway from layer 3 of the EC directly to CA1, often referred to as the temporoammonic or TA-CA1 pathway. Granule cells of the DG send their axons (called "mossy fibers") to CA3. Pyramidal cells of CA3 send their axons to CA1. Pyramidal cells of CA1 send their axons to the subiculum and deep layers of the EC.

  6. Betz cell - Wikipedia

    en.wikipedia.org/wiki/Betz_cell

    Betz cells are not the sole source of direct connections to those neurons because most of the direct corticomotorneuronal cells are medium or small neurons. [3] While Betz cells have one apical dendrite typical of pyramidal neurons, they have more primary dendritic shafts, which can branch out at almost any point from the soma (cell body). [4]

  7. Stratum lucidum of hippocampus - Wikipedia

    en.wikipedia.org/wiki/Stratum_lucidum_of_hippocampus

    It is the tract of the mossy fiber projections, both inhibitory and excitatory from the granule cells of the dentate gyrus. One mossy fiber may make up to 37 connections to a single pyramidal cell, and innervate around 12 pyramidal cells on top of that. Any given pyramidal cell in the stratum lucidum may get input from as many as 50 granule cells.

  8. Apical dendrite - Wikipedia

    en.wikipedia.org/wiki/Apical_dendrite

    CA1 pyramidal cells make up a homogeneous population which together with relatives in subiculum comprise the primary output cells of the hippocampal formation. [2] Primary excitatory inputs are via glutamatergic CA3 Schaffer collaterals (both ipsi- and contralateral), which contact dendritic spines on the apical and basal dendrites in strata ...

  9. Schaffer collateral - Wikipedia

    en.wikipedia.org/wiki/Schaffer_collateral

    Schaffer collaterals are the axons of pyramidal cells that connect two neurons (CA3 and CA1) and transfer information from CA3 to CA1. [5] [6] The entorhinal cortex sends the main input to the dentate gyrus (perforant pathway). From the granule cells of the dentate gyrus, connections are made to the CA3 regions of the hippocampus via mossy fibers.
