pyramidal cell

Etymology: Gk, pyramis + L, cella, storeroom
a neuron with a pyramid-shaped cell body in the gray matter of the cerebral cortex.

pyramidal cell

A large, common neuron found in the cerebral cortex. Pyramidal cells are flask-shaped or triangular, and, in the parts of the cortex with six layers, they occupy the fifth layer. Pyramidal cell dendrites project up into the most superficial layer of the cortex, while pyramidal cell axons run in the opposite direction, i.e., downward and out of the cortex.

21] However, the present study did not show clear morphology of hippocampal pyramidal neurons probably due to higher caffeine doses might be associated with a decreased density of cortical A1R and hippocampal BDNF levels.
Within this region, large pyramidal neurons of layers III and V are presumed to be subject to the cortical hyperexcitability that causes excessive and brief myoclonus discharges down their axons.
However, immature pyramidal neurons express highly motile filopodia and lack spines.

The slides were observed under a light microscope and images were captured to visualize the arrangement of pyramidal neurons in the medial prefrontal cortex (mPFC) and each hippocampal region: CA1, CA2, CA3, and DG.
The pyramidal neurons of the CA1 area of the hippocampus are the most sensitive neurons to hypoxia and subsequent death during ischemic conditions [13-15].
Moreover, TEN increased the frequency and amplitude of sEPSCs but only improved the frequency of mEPSCs rather than amplitude in hippocampal CA1 pyramidal neurons.
