Chapter 15, Problem 3CP
Summary Introduction
To determine:
The receptor which provides more precise sensory information, where receptor A has a circular receptive field on the skin surface with diameter 2.5 cm and receptor B has a circular receptive field 7.0 cm in diameter.
Concept introduction:
The particular region of the sensory space is the receptive field of an individual sensory neuron. The receptor B has more receptive field of 7.0 cm as compared to receptor A, which is having less circular receptive field of 2.5 cm.

- 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.arrow_forwardWhat are the receptor cells in the eye that are most sensitive to light and that give an image in black / white (grayscale)?arrow_forwardA scientist has dissected out a small section of the retina and is able to directly record the action potential firing rate in a single ganglion cell. Assume there is a on-center off-surround bipolar cell connected to an on-center off-surround ganglion cell. When applying ‘Stimulus 1’ the scientist records a moderate action potential rate. When applying ‘Stimulus 2’ the rate of action potentials increases substantially. In the context of this experiment no illumination is an option as a 'Stimulus'. ‘Stimulus 2’ would result in what response in the bipolar cell (the one connected to the ganglion cell the scientist is measuring)?
