Disynaptic inhibition between neocortical pyramidal cells mediated by Martinotti cells. [PDF]
Neuron, 2007 Reliable activation of inhibitory pathways is essential for maintaining the balance between excitation and inhibition during cortical activity. Little is known, however, about the activation of these pathways at the level of the local neocortical microcircuit. We report a disynaptic inhibitory pathway among neocortical pyramidal cells (PCs). Inhibitory

Hippocampal pyramidal cells: the reemergence of cortical lamination [PDF]
Brain Structure and Function, 2011 The increasing resolution of tract-tracing studies has led to the definition of segments along the transverse axis of the hippocampal pyramidal cell layer, which may represent functionally defined elements.

Excitatory and inhibitory effects of HCN channel modulation on excitability of layer V pyramidal cells. [PDF]
PLoS Computational Biology, 2022 Dendrites of cortical pyramidal cells are densely populated by hyperpolarization-activated cyclic nucleotide-gated (HCN) channels, a.k.a. Ih channels. Ih channels are targeted by multiple neuromodulatory pathways, and thus are one of the key ion-channel ...

All active hippocampal pyramidal cells are place cells. [PDF]
iScienceHippocampal place cells – neurons whose activity is modulated by spatial position – are considered an essential substrate of spatial cognition. Despite decades of research, the fraction of hippocampal place cells remains debated, with studies reporting between 20% and 90% of the recorded populations. This raises the question of whether distinct subsets

Change of Nurr1 expression in mouse hippocampal CA3 region following excitotoxic neuronal damage [PDF]
Iranian Journal of Basic Medical Sciences, 2020 Objective(s): Nuclear receptor-related protein 1 (Nurr1), one of immediate-early genes, is a member of orphan nuclear receptor family. The aim of this study was to investigate the time-dependent change of Nurr1 protein expression in the mouse hippocampal

Age-related changes in the human primary motor cortex: A macroscopic and microscopic study
Asian Journal of Medical Sciences, 2021 Background: Cerebral hemisphere has outer gray matter and inner white matter. The cerebrum is folded into gyri and sulci in order to accommodate it in the skull. The thickness of the gray matter varies at sulci and gyri and the mean thickness may be from

Subliminal messages in hippocampal pyramidal cells [PDF]
The Journal of Physiology, 2002 Synaptic activity regulates gene transcription in neurons. The coupling between synaptic transmission and transcription is accomplished by the second messenger calcium, which enters the cell through synaptic receptors and voltage-gated calcium channels and binds enzymes that activate transcription factors.
