A neuron conveys information about the strength of stimuli by varying the rate in which the stimulus is fired.
If a neuron, or other excitable tissue, is stimulated by a stimulus of threshold strength or greater strength..
A sensory Neuron picks up the stimulus from the environment and changes it into a nerve impulse.
Threshold stimulus
Sensory neuron
The stimulus is detected by the sensory receptor. The sensory receptor stimulates a sensory neuron. The sensory neuron transmits to the interneuron in the spinal cord. The interneuron stimulates a motor neuron. The motor neuron communicates to the muscle. The muscle(effector) then produces the response allowing the body to respond to the stimulus.

The strength of a stimulus is coded in the frequency of action potentials, not in the amplitude.
An interaction with the world.
the neuron pathway
Number of times the neuron fires
False( When a stimulus acts on a neuron, it increases the permeability of the stimulated point of its membrane to sodium ions. )
When a stimulus stimulates a neuron above the threshold, the action potential is generated.
