What does your map of cutaneous sensations tell you about the distribution of sensory receptors in the skin?
Applying a pressure stimulus to the fluid-filled capsule of an isolated Pacinian corpuscle causes a brief burst of action potentials in the afferent neuron, which ceases until the pressure is removed, at which time another brief burst of action potentials occurs. If an experimenter removes the capsule and applies pressure directly to the afferent neuron ending, action potentials are continuously fired during the stimulus. Explain these results in the context ofadaptation.
a) Based upon how the neural membrane functions, briefly explain how electrical
stimulation can cause a neuron to generate an action potential. Describe in one
sentence a type of action potential that can be generated by electrical stimulation, but
that cannot be generated by synaptic inputs.
b) The central part of the retina consists largely of cones, which are responsible for
colour vision in normal sight. However, presently available retinal prostheses are not
able to reliably provide a perception of colour for people implanted with these devices.
Explain why people with a retinal prosthesis are currently unable to reliably perceive
colour.
