What is the function of cells of Martinotti?
They are present in all six layers of cortex (except layer 1). Whenever Pyramidal neurons (another type of neurons that are also found in cortical layers) are over-excited, cells of Martinotti will send inhibitory signals to surrounding neurons. Simply, they are involved in "cortical dampening mechanism".
What is the function of T-cells?
this is my question what is the function of t-cells?
What is the function of bulliform cells?
The function of bulliform cells is to roll the leaves
What are the types of neurons that can be found in the external granular and external pyramidal layers of neocortex?
in external granular (layer 2) = stellate + small pyramidal neuronsin external pyramidal (layer 3) = medium pyramidal neurons
Function of the cytoskeleton in the cells of living organisms?
function of the cytoskeleton in the cells of living organisms?
What is the location and function of the pyramidal cells and tracts of the brain?
Location: Medulla oblongata Function: To transmit nerve impulses from one side of the body to the other
Pyramidal cells are located in the region?
cerebral cortex
What are the sites of origin of the pyramidal tract?
the pyramidal cells in layer 5 of areas 4, 6 ,3-1&2
Is Spastcity pyramidal or extra pyramidal?
pyramidal
What is peduncle?
A cerebral peduncle are fibers that are bundled together that contain pyramidal cells. The cells are found in all parts of the cerebral isocortex
Damage to the pyramidal cells of the cerebral cortex would directly affect?
voluntary motor activity.

What is the type of neurons that are present in the internal pyramidal layer of neocortex?
The "internal pyramidal layer" is the 5th layer of neocortex. You can find lots of large pyramidal neurons at this layer and they project their axons to subcortical structure.You can also find the "giant pyramidal cells of Betz" at this 5th layer of the motor areas. They are very large and they send their axons to corticospinal tract.
Primary motor area sends impulses via to control skeletal muscles?
The primary motor cortex send nervous impulses via the pyramidal cells, down the pyramidal tracts in the spinal cord.

What is the difference between pyramidal and extrapyramidal system?
The Similarity: Pyramidal and extra-pyramidal system are the descending tracts (motor tracts) of spinal cord.The Difference:1) Their tracts -Pyramidal system = lateral and anterior corticospinal tracts + corticobulbar tractExtra-pyramidal system = rubrospinal + olivospinal + lateral and medial reticulospinal + tectospinal + vestibulospinal tracts2) "Extrapyramidal tracts" don't reach their targets by traveling through the "pyramids of medulla". Pyramidal tracts go through the pyramids of medulla.3) Pyramidal tracts may directly innervate motor neurons of spinal cord or brainstem (anterior horn cells or certain cranial nerve nuclei). But, extrapyramidal tractsindirectly control the anterior horn cells (for modulation and regulation)4) Pyramidal system is responsible for fine, isolated, precise and specific movements. Extrapyramidal system is responsible for gross, syngergic movements which require the activity of large groups of muscles
What is theprecentral gyrus?
The precentral gyrus is in the cerebrum and can be found in the frontal lob of the forebrain. Its function is to begin pyramidal nerve tracts.
