Neuroplasticity and rehabilitation Neurorehabilitation is the process of attempting to restore the cognitive or motor function for patients with disorders of the nervous system. This process involves approaches intended to reduce impairments and disabilities, and ultimately improving quality of life. Neuroplasticity is the brain 's ability to remodel or reorganize itself by forming new neural connections. This allows the neurons to compensate for injury and disease, and to adjust their activities

able to detect a change in the environment and they are able to create an action potential with sodium ions. The schwann cell wraps around the axon and is used to insulate it from the myelin sheath. The cell body is in a ganglion which is close to the CNS. There is also the axon, this is short communication route which is between the cell body and the axon terminals, in this there

the soma, the axon and the myelin. Dendrites are the branches of the neuron which receive messages and are attached to the soma. The soma contains the nucleus and is mainly responsible for keeping the cell alive and running. Axon is the message carrier of the neuron and it does so as a fiber attached to soma. Lastly, the myelin is a fatty substance made by glial cells that serves as a protecting sheath around the axons. It also speeds up the neural message traveling down the axon. 2. How do neurons

system. Brain control all the human system by sending a message through the spinal cord and PNS. Most of the actions occurred in the brain. A neuron is the basic unit of the nervous system; it has two extensions from cell body called dendrites and axons. Axon sends

Families have seen personified toys, cars, vegetables, robots, and monsters, but now emotions? Pixar Animation and Walt Disney Pictures’ movie Inside Out, took a unique look at its protagonist Riley, her emotions, personality, and memories. One of five emotions, Joy, so aptly stated “Do you ever look at someone and wonder, "What is going on inside their head?" Well, I know. Well, um, I know Riley 's head.” After viewing Inside Out, a person feels like they understand pruning felt by Riley in an

depending on the subclass (Crone et al., 2008). V0d cells have recently been shown to not only project their axons toward contralateral motor neurons, but exhibit increased activity during locomotion, thereby contributing to left-right coordination (Griener et al., 2015). V1 cells, which can be subdivided by function into Renshaw cells, Ia and other inhibitory subtypes, project their axons ipsilaterally. Experiments in embryonic chick suggest that many of these cells synapse with motor neurons (Wenner

Inside The spinal cord filled with neurons without having myelin sheath in their axons, Because it looks gray. The spinal cord connected to the thirty-one pairs of peripheral. Spinal nerves, The wire at the back or dorsal part is attached to the sensory spinal nerves. There are two (left and right) dorsal origins through which sensory

through its branching dendrites, and conducts signals through its axons. Some of our axons are enclosed in a myelin sheath, which enables faster transmission of the signal. If the combined received signals exceed a certain minimum threshold, the neuron “fires” a signal, transmitting an electrical impulse, also known as the action potential, down its axon by way of a

nervous system. In the human brain, glia are estimated to outnumber neurons by about 10 to 1 (SFN 2000). The axon of a neuron (nerve cell) is a long, slender projection that conducts electrical impulses away from the neuron's cell body, or soma. The axons of neurons may or may not be coated with myelin. Myelin is a phospholipid layer that is an outgrowth of glial cells. Myelin-coated axons appear white, and thus these regions of the CNS are called "white matter," while "gray matter" is composed of

called oligodendrocytes whereas neuroglial cells in the PNS is called Schwann cells. Both types of neuroglia cells create myelin to insulate neurons and speed up the transmission of neural messages, but only the Schwann cells in the PNS can aid in axon
