By the migration of a potential charge.
When a neuron gets stressed (stretch receptors) or receives a signal (a neurotransmitter) it can either cause a positive or negative change in that neurons membrane potential. If the change is POSITIVE enough, and lets in enough Na+ through ligand gated ion channels (where the neurotransmitters bind) , then the cell will be able to fire. Fireing means that a bunch of voltage gated ion channels open to allow more Na+ in, in a chain reaction fashion. As the channel detects a positive change in voltage, it opens its channel to allow even more positive ions to enter the cell. After the Na+ channels open, K+ channels open to let out K+, to help restore the resting potential of about -60. The Na/K pump will help to re-establish the correct resting potential after this chain reaction has moved all the way down the cells axon. The meyelin sheath helps these reactions "jump" down the axon, and therefore makes it faster and more efficient. When the reaction reaches the end terminal of the neuron Ca+ is used instead of Na+, Ca+ has an unusual affect on vesicles, making them want to leave the cell, contained in these vesicles are neurtransmitters, which go to a new cell and the process starts all over again.
Using Cl- instead of Na+ at the ligand gated ion channels in the dendrites will make the cell more negative and harder to depolarize and trigger the voltage gatted Na+ channels. Certain neurotransmitters bind to these Cl channels and different ones bind to the Na+ channels.

What are neurons that carry information between sensory neurons and motor neurons?
Interneurons or association neurons.
What is the area between neurons across which nerve impulses travel?
no, synapse. node of ranvier is between axon and dendrites
Which brain structure functions as a relay station between the cerebellum and other brain structures?
Nothing relays information between neurons. Neurons passes the information to other neurons.
What is the purpose of a synapse?
gap allows information to jump between neurons
What connects the Neurons in the brain at the intersection?
Synapses are connections between neurons through which "information" flows from one neuron to another.
What are the 3 types of neurone?
Sensory neurons, motor neurons, and interneurons. Motor neurons usually carry information to muscles and glands. Sensory neurons carry information from sense organs or free endings to the spinal cord or brain. Interneurons act as a go between.
What is the function of cells in the human body?
Nerve cells specialized on transmitting messages from one part of the body to another. Motor neurons send information away from the central nervous system (CNS). Sensory neurons send information toward the CNS. Inter-neurons send information between motor and sensory neurons.
What do the lower neurons do?
You are probably speaking of "lower motor neurons." These are neurons that send information from the spinal cord to the muscles of the body & they travel within all most of the nerves of the body (like sciatic, median, etc). These neurons are controlled by "upper motor neurons" and control your muscles to allow you to be able to move.
Human Nerve Cells?
Nerve cells specialized on transmitting messages from one part of the body to another. Motor neurons send information away from the central nervous system (CNS). Sensory neurons send information toward the CNS. Inter-neurons send information between motor and sensory neurons.
What is the relationship between a stimulus and a nerve impulse?
The neuron is the functional portion of the central nervous system, carrying impulses to the designated location. Neurons also have the role of interpreting an impulse, and waiting for a response. Neurons fall under the category of sensory neurons, interneurons and motor neurons.
What is the link between neuron pathways and learning?
our core learning is recorded in the set of neurons. sensory neurons send decoding messages to the motor neurons. in case the information generated by one set of neurons is insufficient to solve the problem, the inter neurons send furthar questions through the pathways to another set of neurons and carries back the information to the earlier set of neurons. un answered questions get recorded in a new set of neurons as new experience.
Most neurons send information to?
Other neurons
