Impulse

An impulse (in neurology) is a short-term electrical signal that is transmitted along nerve fibers from one neuron to another. Impulses are the main way of transmitting information in the nervous system.

When a neuron fires, it generates an impulse, changing the electrical charge inside the cell. This results in a rapid, reversible change in the neuron's membrane potential, called an action potential. The action potential propagates along the neuron axon at speeds of up to 120 m/s.

Having reached the end of the axon, the impulse causes the release of the neurotransmitter into the synaptic cleft. The neurotransmitter binds to receptors on the membrane of the next neuron, which either excites or inhibits the generation of a new impulse in that neuron.

Thus, the sequential transmission of nerve impulses along chains of neurons allows the nervous system to quickly transfer information over long distances throughout the body. It underlies all neural processes such as movement, sensation, thinking and memory.

Impuls is a word that can be found in various areas of life, from medicine to art. In this review, we will look at the word "impulse" in the context of scientific research and its application in neuroscience.

In medicine, the term "nervous impulse" is used to describe the excitation of the nervous system. Nerve impulses are transmitted through neurons and cause changes in the state of the body. The speed of the pulses may vary and depends on various factors such as age, gender,
