A period after an initial stimulus when a neuron is not sensitive to another stimulus is the?
After the generation and propagation of an action potential along a neuron, the cell becomes depolarized to the point where there is no potential for further signaling until the cell re-polarizes through the action of ion pumps. This very brief period is called the refractory state.
Period during which potassium ions diffuse out of the neuron due to a change in membrane permeability?
Membrane potential - a nerve cell set and ready to fire;"The wave of reverse polarity" i.e. sodium versus potassium trans-cell-membrane ion passaging - a nerve cell firing; andRecharge period - the regeneration time.
State of an unstimulated neuron's membrane?
Polarized
What is the small change in the charge across a neuron's membrane called?
Action Potential
The first voltage-regulated gates encountered along the neuron membrane which initiate the formation of action potentials are located on the neuron near the?
axon hillock
Period of reploarization of the neuron during which it cannot respond to a second stimulus?
The absolute refractory period. This period occurs after the action potential has been initiated and is a result of inactivation of the sodium channels. These sodium channels would normally open up to allow sodium influx into the cell during an action potential. The absolute refractory period occurs during an ongoing action potential and is the period in which a subsequent action potential absolutely cannot be generated.This should not be confused with the relative refractory period which occurs immediately following the absolute refractory period (during membrane hyperpolarization). During this period a subsequent action potential is possible, but more difficult to attain.
Is the neuron ready to fire during the refractory period?
Refractory period
What is the absolute refractory period?
Absolute Refractory Period:It is the interval during which a second action potential absolutely cannot be initiated, no matter how large a stimulus is applied.ORAfter repolarization there is a period during which a second action potential cannot be initiated, no matter how large a stimulus current is applied to the neuron. This is called the absolute refractory period, and it is followed by a relative refractory period, during which another action potential can be generated

The neuron cannot respond to a second stimulus no matter how strong?
Absolute refractory period
Absolute refractory period relative refractory period?
In absolute refractory period, none of channels are reconfigured, so that second active potential cannot be generated no matter how large the stimulus current is applied to the neuron. In contrast, in relative refractory period, some but not all of channels are reconfigured, another action potential can be generated but only by a greater stimulus current thatn that originally needed.
What is the period of time during which the neuron cannot generate another action potential called?
refractory period
What is the charge on the inside membrane during the resting membrane potential?
The resting membrane potential of a typical neuron is around -65mV
Period during which potassium ions diffuse out of the neuron's membrane?
sodium-potassium pump
It is the membrane potential of a neuron at rest?
Yes,the membrane potential of a neuron is at rest because it is the difference in electrical charge between inside and outside a resting neuron.
What is the estimated length of refractory period for pyramidal neuron compared to length of action potential?
Their is none
When a neuron is resting the inside of the cell membrane is?
When a neuron is resting then inside of the cell membrane is more negative than outside.
