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.

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.

An Attempt at a Unified Theory of the Neocortical Microcircuit in Sensory Cortex

open access: yesFrontiers in Neural Circuits, 2020
The neocortex performs a wide range of functions, including working memory, sensory perception, and motor planning. Despite this diversity in function, evidence suggests that the neocortex is made up of repeating subunits (“macrocolumns”), each of which ...

Making Waves in the Neocortex [PDF]

open access: yesNeuron, 1997
Our current understanding of cortical oscillators is decidedly weak. Their phenomenology needs closer study. For example, how much do the various specific subclasses of neurons participate during various oscillations, how do excitatory and inhibitory neurons interact, how large are synchronous rhythmic cell assemblies, and how and when do they alter ...

Temporal Flexibility of Systems Consolidation and the Synaptic Occupancy/Reset Theory (SORT): Cues About the Nature of the Engram

open access: yesFrontiers in Synaptic Neuroscience, 2019
The ability to adapt to new situations involves behavioral changes expressed either from an innate repertoire, or by acquiring experience through memory consolidation mechanisms, by far a much richer and flexible source of adaptation.

Neuronal Polarity in the Embryonic Mammalian Cerebral Cortex

open access: yesFrontiers in Cellular Neuroscience, 2017
The cerebral cortex is composed of billions of neurons that can grossly be subdivided into two broad classes: inhibitory GABAergic interneurons and excitatory glutamatergic neurons.

Electro-oscillographic correlation between dorsal raphe nucleus, neocortex and hippocampus during wakefulness before and after serotoninergic inactivation

open access: yesBrazilian Journal of Medical and Biological Research, 1999
Theta rhythm in many brain structures characterizes wakefulness and desynchronized sleep in most subprimate mammalian brains. In close relation to behaviors, theta frequency and voltage undergo a fine modulation which may involve mobilization of dorsal ...

Ubiquitous Neocortical Decoding of Tactile Input Patterns

open access: yesFrontiers in Cellular Neuroscience, 2019
Whereas functional localization historically has been a key concept in neuroscience, direct neuronal recordings show that input of a particular modality can be recorded well outside its primary receiving areas in the neocortex. Here, we wanted to explore

LIS1 determines cleavage plane positioning by regulating actomyosin-mediated cell membrane contractility

open access: yeseLife, 2020
Heterozygous loss of human PAFAH1B1 (coding for LIS1) results in the disruption of neurogenesis and neuronal migration via dysregulation of microtubule (MT) stability and dynein motor function/localization that alters mitotic spindle orientation ...

The Neocortex: Instrument of Transcendence or Reproducer of Competition? An Analysis of the Human Neocortex in Preserving or Transcending Competitive Structures from the Perspective of Spirit–Brain Interaction

open access: yes
This paper seeks to examine, from a trans-psychological perspective, the place of the neocortex in the human psyche and to analyze its role in reproducing competition despite its apparent complexity. The central thesis of the paper is that in the absence
