Abstract For those who know, anatomy quite often reveals function. This chapter outlines the cellular and regional neuroanatomy of mammalian neocortex and also discusses the specific thalamic nuclei that connect primary sensory regions to the sensors and the higher-order thalamic nuclei that mediate some of the interactions between ...

Development of isolated neocortex
Experientia, 1973La migration des neuroblastes et la croissance des aires dendritiques de base des neurones pyramidaux font ici l'objet d'une etude portant sur les regions IV et Vb du neocortex cerebral isole de rats de souche Wistar. La migration des neuroblastes s'effectuait normalement et aboutissait au dispositif habituel ordonne en 6 regions.

Experts review the latest research on the neocortex and consider potential directions for future research. Over the past decade, technological advances have dramatically increased information on the structural and functional organization of the brain, especially the cerebral cortex.

Neuronal Domains in Developing Neocortex
Science, 1992The mammalian neocortex consists of a mosaic of columnar units whose development is poorly understood. Optical recordings of brain slices labeled with the fluorescent calcium indicator fura-2 revealed that the neonatal rat cortex was partitioned into distinct domains of spontaneously coactive neurons.

Trends in Neurosciences, 1979
Ideas concerning the involvement of cerebral neocortex in learning have changed dramatically since Pavlov announced in 1927 that mammals deprived of neocortex were incapable of learning even the simplest of conditional responses. The view presented here is that quite the opposite is the case; that the neocortex is not essential for learning under ...

Experimental Gerontology, 2003
Neurostereology has been applied to quantitative anatomical study of the human brain. Such studies have included the total neocortical number of neurons and glial cells, the estimated size distribution of neocortical neurons, the total myelinated fiber length in the brain white matter, the total number of synapses in the neocortex, and the effect of ...

Brain neocortex immunomodulation in rats
Brain Research, 1988The influence of the cerebral neocortex on the immune system was studied in groups of male Wistar rats after lesioning the right or the left fronto-parietal cortex. In left-lesioned rats, mitogenesis of T-lymphocytes induced either by phytohemagglutinin or Urtica Dioca Agglutinin was depressed by about 25-40% as compared to controls.

Neocortex, Manifold, Catastrophe
1988A complicated terminology is involved in adapting Thom’s ideas to the graphic mapping of the animal—man discontinuity, and it must be introduced carefully so that no important assumptions are ignored.

In this chapter I shall attempt to derive the outlines of a theory of neocortical evolution from a series of observations based mainly on the anatomy and physiology of cerebral cortex in living animals. Such an exercise in evolutionary inference is by its nature a speculative enterprise.
