Isocortex - an overview | ScienceDirect Topics
By far the greatest area of the cerebral cortex in the human brain is devoted to six-layered homotypical isocortex (or neocortex), also known as association isocortex. Association isocortex can be subdivided into two major zones: modality-specific (unimodal) and …
Neocortex - Wikipedia
The neocortex, also called the neopallium, isocortex, or the six-layered cortex, is a set of layers of the mammalian cerebral cortex involved in higher-order brain functions such as sensory perception, cognition, generation of motor commands, [1] spatial reasoning and language. [2]
Isocortex - e-Anatomy - IMAIOS
In humans, the isocortex is involved in higher functions such as sensory perception, generation of motor commands, spatial reasoning, conscious thought and language. There are two types of cortex in the isocortex – the true isocortex and the proisocortex.
Isocortex - ScienceDirect
Jan 1, 2015 · The isocortex comprises the phylogenetically youngest cortical areas, which develop a six-layered structure during fetal stages and maintain this lamination pattern in adulthood. Thus, it resembles the evolutionary defined neocortex and the developmentally defined homogenetic cortex.
A taxonomy of transcriptomic cell types across the isocortex …
Jun 10, 2021 · The isocortex and hippocampal formation (HPF) in the mammalian brain play critical roles in perception, cognition, emotion, and learning. We profiled ∼1.3 million cells covering the entire adult mouse isocortex and HPF and derived a transcriptomic cell-type taxonomy revealing a comprehensive reperto …
BrainInfo - University of Washington
Also known as 'isocortex', the neocortex is composed of two subdivisions: true isocortex and proisocortex (Carpenter-1983). In the human it constitutes 96% of the surface area of the cerebral cortex (Zilles-1990),
Frontiers | Olfaction, navigation, and the origin of isocortex
While in reptiles and birds the most expanding component (the dorsal ventricular ridge) displays an overall nuclear shape and derives from the lateral and ventral pallium, in mammals a dorsal pallial, six-layered isocortex shows the most remarkable elaboration.
Olfaction, navigation, and the origin of isocortex - PMC
Oct 27, 2015 · In this article, we propose that the origin of the isocortex was driven by behavioral adaptations involving olfactory driven goal-directed and navigating behaviors. These adaptations were linked with increasing sensory development, which provided selective pressure for the expansion of the dorsal pallium.
Evo-devo and the primate isocortex: the central organizing role …
We describe gradients of neurogenesis within the isocortex and their effects on adult cytoarchitecture within and across species. Longer duration of neurogenesis in the caudal isocortex is associated with increased neuron number and density per column relative to the rostral isocortex.
The regional variation of laminar thickness in the human isocortex …
Nov 9, 2023 · The human isocortex consists of tangentially organized layers with unique cytoarchitectural properties. These layers show spatial variations in thickness and cytoarchitecture across the neocortex, which is thought to support function through enabling targeted corticocortical connections.
