- Awareness of a stimulus is called a ________.When a receptor cell detects a specific kind of stimulus, what happens to the stimulus energy?If the response to a stimulus is a change from a negative potential to a less negative potential, the change is called: stimulus response Repolarization Depolarization Stimulus recovery
- Precise localization of a somatosensory stimulus is improved by: Increasing frequency coding Increasing population coding Decreasing receptive field size O Lateral inhibition Increasing receptive field sizeAction potential frequency in phasic receptors with a prolonged stimulus action potential frequency in tonic receptars with a prolonged stimulus. Greater than Less than Equal toDescribe the flow of generation of receptor potential when sensory receptors detected stimuli.
- Does a stimulus applied to a receptor always lead to depolarization or a receptor potentialIf there is an increase in stimulus strength on a pain receptor but more pain is not felt, which of the following would explain this? sodium channels are opened with the stimulus stimulus increase from submaximal to subthreshold pain receptor adapt to the large stimulus frequency of action potentials os unchangedNot every sensory signal results in conscious awareness ofa stimulus. Explain
- The amplitude, frequency and duration of the stimulus delivered can be adjusted. Looking at the image of the stimulator panel, what is the frequency of the stimulus to be delivered in Hz?The "All or None" response means that: A stimulus causes depolarization and repolarization regardless of the strength of the stimulus There is no threshold for an electrical stimulus signal to reach before depolarization and repolarization O Potassium channels open for depolarization and sodium channels open for repolarization A stimulus has to be strong enough for depolarization to occur followed by repolarizationIf you present a stimulus that is within a neuron's receptive field, what will happen? The neuron will increase its firing rate The neuron will decrease its fıring rate The neuron may increase or decrease its firing rate depending on the stimulus The neuron may or may not have a change in response
