a periodic production of action potentials even without synaptic input
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).
The process by which inhibitory and excitatory post-synaptic potentials summate and control the rate of firing 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.
yes
Excitatory neurotransmitter
Yes, caffeine effects the brain by increasing the neuron firing. Caffeine also speeds up other things like your heart rate.
True
Resting potential
Resting potential.
The state of a neuron when it is not firing a neural impulse is called the resting potential. This is when the neuron is negatively charged inside compared to outside, waiting for a stimulus to change its electrical charge and initiate an action potential.
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.
