Spontaneous firing rate of a neuron?
a periodic production of action potentials even without synaptic input
What determines whether a neuron will have an action potential triggered?
The effect upon the target neuron is determined not by the source neuron or by the neurotransmitter, but by the type of receptor that is activated. A neurotransmitter can be thought of as a key, and a receptor as a lock: the same type of key can here be used to open many different types of locks. Receptors can be classified broadly as excitatory(causing an increase in firing rate),inhibitory(causing a decrease in firing rate), or modulatory(causing long-lasting effects not directly related to firing rate).
What is Neural integration in the somatosenory system?
The process by which inhibitory and excitatory post-synaptic potentials summate and control the rate of firing of a neuron.
A neuron reaches its trigger point when?
Action potential is nerve impulse triggered when a neuron reaches its threshold, or trigger point for firing. Threshold trigger point for a neuron's firing about negative 50 millivolts.
What is mean by the all or none response of a neuron?
The simplest sense, the all-or-none principle of neuronal firing means that a neuron will either fire or it won't, there is no "half" firing. When a neuron receives excitatory input.
When a neuron fires is there such thing as partial firing?
yes
Does caffeine effect the brain?
Yes, caffeine effects the brain by increasing the neuron firing. Caffeine also speeds up other things like your heart rate.
Can the firing of one neuron produce temporal summation?
True
The state of the neuron when not firing a neural impulse is known as?
Resting potential
What do you call the state of a neuron when it is firing a neural impulse?
Resting potential.
What do you call the state of a neuron when it is not firing a neural impulse?
Resting potential.
What stops muscle stimulation when the motor neuron ceases firing?
Acetylcholinesterase is the enzyme that stops muscle stimulation when the motor neuron ceases firing. This enzyme enables acetyl and choline to release their binding sites.
