- 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_forwardSuppose that a sensory neuron in the periphery generates a trainof action potentials, and synaptically excites an interneuronin the CNS.

- Why is hyperpolarization important?arrow_forwardTwo separate post-synaptic interneurons receive synaptic potentials from afferent neurons in the periphery. The dendrites of one these interneurons receive an excitatory post-synaptic potential (EPSP) and an inhibitory post-synaptic potential (IPSP) of equal magnitude at the same time. The dendrites of the other interneuron receive one excitatory post-synaptic potential that is the same sized as the EPSP and IPSP received by the other interneuronarrow_forwardWhich of the following is true regarding the difference between graded and action potentials? a.) Action potential occur only when the surface of the neuron is myelinated, but graded potentials occur in both in both myelinated and non-myelinated neurons. b.) The magnitude of action potential depends on the magnitude of the stimulus, whereas graded potentials are all or none. c.) The magnitude of graded potential depends on the magnitude of the stimulus, whereas action potentials are all or none.arrow_forward
- Which type of neuron, based on its shape, is bestsuited for relaying information directly from one neuron toanother? Explain why.arrow_forwardAn in-class test of the opponent process theory of color vision relied on a basic principle of neurophysiology to explain color afterimages. What is this basic principle? O If a cell is excited or inhibited for a long period of time by a strong stimulus, when the stimulus is terminated the cell will temporarily "undershoot" or "overshoot" its normal activity rate. Receptor cells are able to respond to a wide variety of sensory inputs, but sensory neurons are only able to respond to a select few types of inputs. Sensory receptors are the first cells to process incoming stimuli, while sensory neurons have to rely on input from receptors in order to function. Retinal ganglion cells act in a non-intuitive "opposite" fashion, being inhibited by a strong stimulus, but excited by a weak stimulus.arrow_forwardTrace the pathway of the action potential to the tastearea of the cerebral cortex.arrow_forward
