What are CR cells?
CR cells are pioneer neurons that populate the MZ overlying the entire cortical neuroepithelium, stretching from medial to lateral domains into the archi-, neo-, and piriform (PC) cortices.
What are the layers of cerebral cortex?
There are six layers of cerebral cortex:
- Molecular (plexiform) layer.
- External granular layer.
- External pyramidal layer.
- Internal granular layer.
- Internal pyramidal layer.
- Multiform (fusiform) layer.

What are Martinotti cells?
Martinotti cells are small multipolar neurons with short branching dendrites. They are scattered mainly in cortical layer III and V with axonal arborization in cortical layer I and make contacts with the distal tuft dendrites of pyramidal cells in multiple columns.
What are retzius cells?
What is a Cajal-Retzius cell? A transient class of neurons found in the surface of the developing cerebral cortex of mammals. Cajal-Retzius cells have a peculiar morphology with distinctive horizontal dendrites, and they release the neurotransmitter glutamate.
What are the 3 main functions of the cerebral cortex?
Areas of the Cerebral Cortex. The cerebral cortex can be characterised as being made up of three types of divisions, which serve different purposes: sensory, motor, and association areas. The combination of these three areas account for most of human’s cognition and behavior.
Are Betz cells upper motor neurons?
The pyramidal cells of cortical layer V (also called Betz cells) are the upper motor neurons of the primary motor cortex.
Where are Betz cells located?
primary motor cortex
Betz cells are giant motoneurons located in layer Vb of the primate primary motor cortex.
What is the pathophysiology of Cajal Retzius?
CajalâRetzius (CR) cells are thought to be generated from three different progenitor domains located at the margins of the pallium: the cortical hem, which produces the majority of CR cells, the ventral pallium, and the pallial septum. CR cells disperse tangentially from each of these regions to colonize the entire surface of the cerebral cortex.
What are Cajal-Retzius cells?
These cells were discovered by two scientists, Santiago RamĂłn y Cajal and Gustaf Retzius, at two different times and in different species. They are originated in the developing brain in multiple sites within the neocortex and hippocampus. From there, CajalâRetzius (CR) cells migrate through the marginal zone, originating the layer I of the cortex.
What are RamĂłn y Cajal and Retzius cells?
These cells were discovered by two scientists, Santiago RamĂłn y Cajal and Gustaf Retzius, at two different times and in different species. They are originated in the developing brain in multiple sites within the neocortex and hippocampus.
What are the horizontal cells of Cajal?
CajalâRetzius cells (CR cells) (also known as Horizontal cells of Cajal) are a heterogeneous population of morphologically and molecularly distinct reelin-producing cell types in the marginal zone/layer I of the developmental cerebral cortex and in the immature hippocampus of different species and at different times during embryogenesis and
