What does threshold means in respect to neurons response?

In the context of neurons, the threshold refers to the level of stimulation needed to generate an action potential or nerve impulse. Once the input signal surpasses this threshold, the neuron will fire and transmit an electrical signal down its axon. Below the threshold, the neuron remains inactive.


A neuron fires only when its membrane reaches what?

A neuron fires when its membrane reaches a certain threshold potential. This threshold potential is typically around -55 to -65 millivolts. When the membrane potential reaches this level, an action potential is triggered and the neuron fires.


Minimum level of stimulation required to trigger a neural impulse?

The minimum level of stimulation required to trigger a neural impulse is known as the "threshold." This threshold is the minimum amount of neurotransmitter release or electrical stimulation needed to generate an action potential in a neuron. Below this threshold, the neuron will not fire an action potential.


Stimulus threshold of the neuron refers to what?

The stimulus threshold of a neuron, often referred to as the action potential threshold, is the minimum level of stimulation required to trigger an electrical impulse (action potential) in the neuron. When a stimulus exceeds this threshold, it causes sufficient depolarization of the neuron's membrane, leading to the rapid influx of sodium ions and the subsequent propagation of the action potential along the axon. If the stimulus is below this threshold, the neuron remains inactive, and no action potential is generated.


The smallest intensity of a stimulus that you can detect 50 percent of the time is?

The smallest intensity of a stimulus that you can detect 50 percent of the time is called the absolute threshold. This threshold varies depending on the sensory system and the specific stimulus being measured.
