The message that travels through a neuron?
A neural impulse. Specifically, once it fires, an action potential.
A neuron fires only when its membrane reaches what?
When it reaches the nerve impulse threshold, the next neuron will fire..
Where neuron cell bodies located?
The cell body, called the SOMA, is the main part of the neuron. It is the main metabolic center or region of the neuron. The neuron has 3 parts: DENDRITES (inputs), SOMA (cell body), and AXON (output). The axon is the part which FIRES when sufficient inputs reach it at the axon hillock.
Why causes the neurons fire?
Neurons are nerve cells, and they fire to relay messages from neuron to neuron. Neurons fire when a charge jumps across a synapse to the dendrite of a cell. The neuron then fires the charge down it's axon, and the charge travels to the next neuron.
What type of neuron is mirror neuron?
A mirror neuron is a type of neuron found in the brain that fires (i.e. activates) under two conditions: if an animal/person does a certain action (for example, wipe its face) or if the animal/person sees another animal/person do that action. These are individual neurons (or groups) that fire for a specific action, whether the action is seen or done. This is considered significant in social psychology, as it may (partially) neurologically explain why people are prone to imitate simple behaviors.
When a neuron fires is there such thing as partial firing?
yes
The strong stimulus can increase the?
Number of times the neuron fires
When a neuron is depolarized to threshold?
1. The neuron fires an action potential, sending the electrical signal down the axon.
What cause neuron to fire?
The neuron adds up all the excitatory and inhibitory inputs and fires when they reach its threshold of excitation.
What kind of neuron fires when you observe someone elses behavior?
Mirror Neurons. IT--
Refers to the fact that a neuron either fires completely or does not fire at all?
All or none
What refers to the fact that neuron either fires or completely or does not fire at all?
All or none
What refers to the fact that a neuron either fires completely or does not fire at all?
All or none
What was Excitation and Inhibition about?
Excitation and Inhibition occur in the neurons. Excitation is when a neuron becomes depolarized and fires an action potential. Inhibition is when a neuron becomes hyperpolarized preventing it from firing an action potential.
What neuron is before a synapse?
The synapse consists of the two neurons, one of which is sending information to the other. The sending neuron is known as the pre-synaptic neuron (i.e. before the synapse) while the receiving neuron is known as the post-synaptic neuron (i.e. after the synapse).
What kind of potential is it when a neuron fires?
When a signal is sent out from the nervous system it is caused a release of a neurotransmitter that releases an action potential.
The message that travels through a neuron?
A neural impulse. Specifically, once it fires, an action potential.
