Genetic manipulation of reptilian embryos: toward an understanding of cortical development and evolution

open access: yesFrontiers in Neuroscience, 2015
The mammalian neocortex is a remarkable structure that is characterized by tangential surface expansion and six-layered lamination. However, how the mammalian neocortex emerged during evolution remains elusive.

Spread of epileptiform activity in the immature rat neocortex studied with voltage-sensitive dyes and laser scanning microscopy [PDF]

open access: yes, 1994
1. Adult rats and rats with a postnatal age of 3-29 days (PN 3-29) were used for the preparation of in vitro slices of the frontal neocortex. Epileptiform activity was induced by bath application of the gamma-aminobutyric acid-A (GABAA) receptor ...

Synaptic Plasticity in Cortical Inhibitory Neurons: What Mechanisms May Help to Balance Synaptic Weight Changes?

open access: yesFrontiers in Cellular Neuroscience, 2020
Inhibitory neurons play a fundamental role in the normal operation of neuronal networks. Diverse types of inhibitory neurons serve vital functions in cortical networks, such as balancing excitation and taming excessive activity, organizing neuronal ...

Differential Striatal Axonal Arborizations of the Intratelencephalic and Pyramidal-Tract Neurons: Analysis of the Data in the MouseLight Database

open access: yesFrontiers in Neural Circuits, 2019
There exist two major types of striatum-targeting neocortical neurons, specifically, intratelencephalic (IT) neurons and pyramidal-tract (PT) neurons. Regarding their striatal projections, it was once suggested that IT axons are extended whereas PT axons

Subplate Neurons as an Organizer of Mammalian Neocortical Development

open access: yesFrontiers in Neuroanatomy, 2020
Subplate neurons (SpNs) are one of the earliest born and matured neurons in the developing cerebral cortex and play an important role in the early development of the neocortex.

Cholinergic modulation of epileptiform activity in the developing rat neocortex [PDF]

open access: yes, 1989
The effects of carbachol on picrotoxin-induced epileptiform activity and membrane properties of neurons in the developing rat neocortex were examined in an in vitro slice preparation.

Why Neurons Have Thousands of Synapses, A Theory of Sequence Memory in Neocortex [PDF]

open access: yes, 2015
Neocortical neurons have thousands of excitatory synapses. It is a mystery how neurons integrate the input from so many synapses and what kind of large-scale network behavior this enables.

Effects of neonatal dexamethasone and CpdA on the expression of genes for apoptosis regulator proteins in the neonatal hippocampus

open access: yesИнтегративная физиология, 2021
Glucocorticoids (GC) are crucial regulators of homeostasis and function. Despite its negative side effects, glucocorticoid therapy in neonates is widely used antenatally for accelerating fetal lung maturation in cases of preterm birth.

Dynamical Mean Field approximation of a canonical cortical model for studying inter-population synchrony [PDF]

open access: yes, 2011
The goal of this paper is twofold. We propose and explore a model to study the synchronization among populations in the canonical model of the neocortex proposed previously by (R.J. Douglas, K.A.C. Martin, A functional microcircuit for cat visual cortex.

The role of thyroid hormones in regulating of fatty acid spectrum of brain lipids: ontogenetic aspect.

open access: yesMedičnì Perspektivi, 2016
In experiments on rats of three age groups the role of thyroid hormones in the regulation of fatty acid spectrum of cortical and hippocampus lipids was studied.
