Question

The correct sequence of sensory processing is

A) sensory adaptation → stimulus reception → sensory transduction → sensory perception.B) stimulus reception → sensory transduction → sensory perception → sensory adaptation.C) sensory perception → stimulus reception → sensory transduction → sensory adaptation.D) sensory perception → sensory transduction → stimulus reception → sensory adaptation.E) stimulus reception → sensory perception → sensory adaptation → sensory transduction.

Answer 1

The correct answer is: B) stimulus reception → sensory transduction → sensory perception → sensory adaptation.

1. Stimulus reception-refers to activation of sensory receptors such as photoreceptor (vision), nociceptor (pain), olfactory receptor (smell), gustatiory receptor (taste) etc.

2. Sensory transduction-usually sensory receptor is connected (via synapse) with afferent neuron (sometimes receptor is by itself sensory nerve ending): stimulation of the sensory receptor activates the neuron, which then transports information about the stimulus to the CNS

3. Sensory perception-. specific processing regions of the brain are incolved in the perception of different stimuli. They are responsible for encoding of the type of stimulus, its location the duration, and the intensity.

4. Sensory adaptation-this phenomenon occurs when the sensory receptors become exposed to stimuli for a prolonged period, so their sensitivity to that stimuli is decreased.
