Neurons (IPA: /njˈÉ'ɹÉ'ns/, also known as neurones and nerve cells) are electrically excitable cells in the nervous system that process and transmit information.
Neurons
A neuron is a cell specialized to conduct electrochemical impulses called nerve impulses or action potentials.

neurons Highly specialized cells that generate and transmit bioelectric impulses from one part of the body to another; the functional unit of the nervous system.
neuron
(noor-on) [Gk. nerve]
A nerve cell; the fundamental unit of the nervous system, having structure and properties that allow it to conduct signals by taking advantage of the electrical charge across its cell membrane.
Neuron A cell in the nervous system that is specialized to carry information through electrical impulses and chemical messengers. Also called a nerve cell.

And gene regulation is at the bottom of what makes a cell decide to become a red blood cell, or a neuron, or a hepatocyte in the liver, or a muscle cell.
A neural network, or neural net for short, is a problem-solving method based on a computer model of how neurons are connected in the brain.
Your peripheral nervous system has two types of neurons that are constantly at work. Neurons that send impulses from the central nervous system to your limbs and organs are called efferent neurons.
When a message is transferred through a neuron it passes to the next neuron via an amazing fast chemical and electrical reaction. Because of its lightning speed, it is often said that a person’s synapses are firing when they are in deep thought.
James Eberwine (University of Pennsylvania Medical School) presented elegant work on the subcellular localization of mRNA in neurons. Different parts of neurons harbor different populations of mRNAs.
synapse - a highly specialized junction between two neurons, or between a neuron and an effector cell (e.g., muscle or gland cell), at which electrical and/or chemical signals are passed from one cell to another.
A fatty substance builds up in the neurons (nerve cells) of people with Tay Sachs. This causes a gradual paralysis and loss of nervous function that leads to death by age 4 or 5.

Hair cells Specialized neurons inside the cochlea of the inner ear; hair cells use a connected bundle of stereocilia to detect motion and initiate the hearing signal-transduction pathway.
There are times when a cell will leave the cycle and quit dividing. This may be a temporary resting period or more permanent. An example of the latter is a cell that has reached an end stage of development and will no longer divide (e.g. neuron).
Intermediate filaments found in neurons and glial cells include peripherin, neurofilaments, and glial fibrillary acidic protein (GFAP).
