Threshold
No, the neuron is not ready to fire during the refractory period. This period occurs immediately after the neuron has fired and is characterized by a temporary inability to generate another action potential.
The neuron adds up all the excitatory and inhibitory inputs and fires when they reach its threshold of excitation.
no it's an "all or nothing"
The threshold potential must be reached for the neuron to fire. This is the level of depolarization that triggers an action potential to be generated and propagated along the neuron.
When a neuron is activated, there is a change in the voltage across the cell membrane at the receptor site. This change is known as a postsynaptic potential and can be either depolarizing (making the neuron more likely to fire an action potential) or hyperpolarizing (making the neuron less likely to fire an action potential).
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.
Depends on the function of the neuron, the range goes from once per sec to 1000 pulses per sec.
A neuron fires an impulse by the influx of sodium ions into the cell. This creates a temporary change in the neuron's membrane potential, leading to depolarization and the generation of an action potential.
All or none
All or none
you cant but at the cove there is fire
