A neuron conveys information about the strength of stimuli by varying the rate in which the stimulus is fired.
A sensory Neuron picks up the stimulus from the environment and changes it into a nerve impulse.

An interaction with the world.
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.

False( When a stimulus acts on a neuron, it increases the permeability of the stimulated point of its membrane to sodium ions. )
When a neuron receives a very strong stimulus, it may reach its threshold potential and fire an action potential. This can lead to the release of neurotransmitters, sending a signal to other neurons. The strength of the stimulus can affect the frequency of action potentials generated by the neuron.
Any stimulus below the neuron's threshold potential will not result in a response, as it is not strong enough to generate an action potential. Neurons require a minimum level of stimulus intensity to reach the threshold potential and fire an action potential.
The first response a neuron makes to a stimulus is called depolarization. This is when the neuron's electrical charge changes, allowing it to transmit an electrical signal down its length to communicate with other neurons.
