- in molecular layer = basket + stellate neurons
- in purkinje cell layer = cell bodies of purkinje neurons
- in granule cell layer = cell bodies of granule + Golgi type 2 neurons

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 does cortex thickening mean?
cortical thickness is a brain morphometric measure used to describe the combined thickness of the layers of the cerebral cortex in mammalian brains,
What are the layers of the stem?
(from inside to out) Heartwood, Xylem, cambium, phloem, bark/outside layer
What is a bundle of neurons held together by several layers of connective tissue?
A tract
What are hair shafts composed of?
Hair shafts are comprised of three distinct layers. These three layers are concentric, and they are called the cortex, cuticle, and medulla.dead epidermal cells
What is in the cerebral cortex?
In the cerebral cortex there are 6 layers of neurons (grey matter).

What is the outermost layer of the human brain?
The outermost protective covering the the brain is the dura mater, the outermost of the meningeal layers.
Where is the cortex located in the brain?
AnswerSince cortex means the outer layer of an inner organ, the cerebral cortex is the outer layer of the cerebrum.(The cerebrum is the 'biggest' part of the brain as you look at a 'naked' brain, with all the loops and whorls on its surface, divided into two parts, the left and right cerebral hemispheres.)If you can imagine the cerebrum to be like a pie, then the crust would be the cerebral cortex. But the 'crust' is much thinner. The cortex is, actually, only the outer few millimeters of the upper brain, known as the cerebrum. It has 6 layers of differing types of neurons, where cognition and long-term memory occur, and is commonly referred to as the 'grey mater' of the brain.The other parts of the brain are the diencephalon, cerebellum, and the brain stem. These parts do not have a cerebral cortex, although the cerebellum does have an outer layer or cortex of its own, called the cerebellar cortex, most of which is actually hidden in interior folding within the cerebellum. The cortex of the cerebellum doesn't make direct connections to the cortex of the cerebrum, as all of the cerebellum's connections to other parts of the brain travel through the pons, a part of the brain stem.
What are cortical pyramidal neurons?
They are neurons that can be found in all six of cortical layers (except layer 1), and they are excitatory projection neurons.

Thin outer layer of gray matter in the brain?
The cerebral cortex is the outer layer of thecerebrum, it is composed of six cell layers of deeply folded and ridged gray matter.
What does cortex thickening mean?
cortical thickness is a brain morphometric measure used to describe the combined thickness of the layers of the cerebral cortex in mammalian brains,
What risks are present with anterior temporal lobectomy?
A specific risk associated with ATL is possible injury to the cerebral cortex, the outer portion of the brain that consists of layers of nerve cells and their connections, during the lobectomy procedure
What are 3 layers of hair?
The 3 layers of hair are the Cuticle (the outer most layer), the Cortex (the middle layer), and the Medulla (the inner most layer).
