Neocortical Lamination: Insights from Neuron Types and Evolutionary Precursors
The neocortex is characterized by lamination of its neuron cell bodies in six layers, but there are few clues as to how this comes about and what is its function. Recent studies provide evidence that evolution from simple three-layer cortex may give insight into this problem. Three-layer cortex arose in the olfactory, hippocampal and dorsal cortex of the early amniote forebrain based on a corti...
متن کاملHierarchical Organization of Neocortical Neuron Types
2 Abstract The neocortex consists of many diverse neuron populations distributed across cortical layers having specialized connectivity and projection patterns. Glutamatergic pyramidal cells, which are cortical projection neurons, reside in all layers except layer 1, while GABAergic nonpyramidal cells are ubiquitous throughout all cortical layers. These broad classes of excitatory and inhibitor...
متن کاملNeural precursor lineages specify distinct neocortical pyramidal neuron types.
Several neural precursor populations contemporaneously generate neurons in the developing neocortex. Specifically, radial glial stem cells of the dorsal telencephalon divide asymmetrically to produce excitatory neurons, but also indirectly to produce neurons via three types of intermediate progenitor cells. Why so many precursor types are needed to produce neurons has not been established; whet...
متن کاملNeocortical Evolution: Neuronal Circuits Arise Independently of Lamination
The evolutionary origin of the six-layered mammalian neocortex has been controversial. New data on genes with layer-specific expression in mammalian cortex have found an expression pattern in avian forebrain neurons consistent with the view that 'cortical' cells and circuits are present in all amniotes, but with different macroarchitectures in birds versus mammals.
متن کاملActive properties of neocortical pyramidal neuron dendrites.
Dendrites are the main recipients of synaptic inputs and are important sites that determine neurons' input-output functions. This review focuses on thin neocortical dendrites, which receive the vast majority of synaptic inputs in cortex but also have specialized electrogenic properties. We present a simplified working-model biophysical scheme of pyramidal neurons that attempts to capture the es...
