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.

We therefore performed in vivo and in vitro experiments to assess novelty exploration and recognition memory by a battery of spontaneous behavioural tests and the effect on hippocampal mossy fiber to CA3 pyramidal cells synapses in wild-type mice after two months of dietary supplementation with H.
The somatic input of CA1 pyramidal cells has been investigated only in the control and the nonsclerotic epileptic groups (Table 2, [18]), since pyramidal cells could be hardly found in the sclerotic CA1 region.
Activation of mGluR5 was tested because of its location on mPFC pyramidal cells (see the Pain-Related Amygdala-Centered Corticolimbic Interactions section).
Putative pyramidal cells and interneurons were distinguished by the spike duration [33], discharge frequency [34], and autocorrelation function [35].
1): CA1 contains small pyramidal cells. Field CA2 is characterized by a narrow, dense band of large pyramidal cells and field CA3 by a broad, loose band of large pyramidal neurons.
In the hippocampus, TrkB-positive cells were mainly concentrated in the granular cell layer of the DG and in the pyramidal cell layer of the CA1, CA3 and CA4 regions (Figure 3).
The model of the pyramidal cell physiology consisted of sets of differential equations that describe the active currents and calcium concentration within each compartment and the propagation of voltage potential between compartments.
To correct for processing-induced changes in the volume of the tissue, we calculated a correction factor assuming that the treatments did not alter the total number of pyramidal cells. In all hippocampi, we examined six or seven disector pairs (pairs of adjacent 2-[micro]m semi-thin sections mounted on slides and stained with toluidine blue).
In rodents, the actions of CA1 pyramidal cells have striking behavioral correlates.
In females, no significant difference was observed in the total volume estimation of the granular and pyramidal cell layers of the hippocampus in SD- or HFD-fed groups (Fig.
In addition to pyramidal neurons, the PFC houses parvalbumin-containing GABAergic interneurons, which heavily modulate pyramidal cell excitability [11].
