cor·tex

 (kôr′tĕks′)
n. pl. cor·ti·ces (-tĭ-sēz′) or cor·tex·es
1. Anatomy
a. The outer layer of an internal organ or body structure, as of the kidney or adrenal gland.
b. The outer layer of gray matter that covers the surface of the cerebral hemisphere.
2. Botany The region of tissue in a root or stem lying between the epidermis and the vascular tissue.
3. An external layer, such as bark or rind.
4. Cytology The region of the cytoplasm of a eukaryotic cell that lies just under the plasma membrane and contains a network of actin filaments and associated proteins that determine the shape of the cell.

[Latin, bark; see sker- in Indo-European roots.]

cortex

(ˈkɔːtɛks)
n, pl -tices (-tɪˌsiːz)
1. (Anatomy) anatomy the outer layer of any organ or part, such as the grey matter in the brain that covers the cerebrum (cerebral cortex) or the outer part of the kidney (renal cortex)
2. (Botany) botany
a. the unspecialized tissue in plant stems and roots between the vascular bundles and the epidermis
b. the outer layer of a part such as the bark of a stem
[C17: from Latin: bark, outer layer]
cortical adj
ˈcortically adv

cor•tex

(ˈkɔr tɛks)

n., pl. -ti•ces (-təˌsiz)
1.
a. the outer region of a body organ or structure, as the outer portion of the kidney.
2.
a. the portion of a plant stem or trunk between the epidermis and the vascular tissue; bark.
b. any outer layer, as rind.
3. the surface tissue layer of a fungus or lichen, composed of massed hyphal cells.
[1650–60; < Latin: bark, rind, shell, husk]

cor·tex

(kôr′tĕks′)
1. The outer layer of an organ or body part, such as the cerebrum or the adrenal glands.
2. The region of tissue next to the outermost layer of plant stems and roots. The cortex lies between the epidermis (the outermost layer) and the vascular tissue. In roots the cortex transfers water and minerals from the epidermis to the vascular tissue, which distributes them to other parts of the plant. The cortex also stores food manufactured in the leaves.

cortex

The outer layer of an internal organ, notably of the brain and each kidney.

It is known that the piriform cortex is able to temporarily store olfactory memories.
So, yesterday's announcements about ARM's new Cortex A75 and Cortex A55 designs are significant for the mobile universe, including automotive technology, IoT and more.
As a mammal sees more of the world, for example, neurons in the visual cortex form more connections to the motor cortices, so that the bucket brigade moves faster and more efficiently.
The new study shows, in the motor cortex this so-called synaptic plasticity no longer functions without the NMDA receptors.
The new Cortex processors are based on the ARMv8 architecture, which was announced in October last year.
Cerebrum includes in its composition, the cerebral cortex (with a thickness between 2mm and 4mm), which is composed of gray matter (composed of local networks of neurons with dendrites and short unmyelinated axons), being located on the surface and covering the white matter (composed of very long myelinated axons which realize global and rapid nervous communication; it contains association fibers, which conduct nerve impulses between neurons corresponding to the same cerebral hemispheres-commissural fibers that connect neurons and gyri, between hemispheres and projection fibers which forms ascending and descending tracts necessary for the transmission of nerve impulses from the cerebrum into the other parts of the brain and/or spinal cord and vice versa).
The latest version of Axon's Cortex software application makes the implementation of multiple video and audio signal paths easier, more efficient and cost-effective than ever.
Although values were unaffected in the frontal cortex, both the occipital cortex and midbrain displayed significant increases after either continuous ETS exposure or ETS exposure restricted to the postnatal 6-13 month period.
A key concept in this memory-prediction model is that of "invariant representations," The cortex is presented with a flux of sensory data but manages to perceive objects as stable.
Obviously, the auditory cortex does not perceive this as sound, but it is able to decipher this neural message as silence.
