Awareness of a stimulus is called a ________.
The ability to localize the site of stimuli depends upon :-a- the type of the stimulated receptorb- connections between the receptor and the sensory cortexc- the rate of adaptation of the stimulated receptorsd- the nature of the stimulus
Detection of the stimulus modality depends upon :-a- the location of the receptors in the bodyb- the magnitude of the stimulusc- the anatomical connections between the receptors and specific sensory areas in the cerebral cortexd- the magnitude of the receptor potential
The brain’s somatosensory cortex does not consist of neurons that receive information equally from all parts of the animal’s body. Describe an example of this by identifying a relevant animal and the body parts that are disproportionately high in neuronal input to the somatosensory cortex.
A pin can be pressed against the skin lightly and elicit no response from the pain receptor. However, if the pin is jabbed into the finger, the pain receptor may be stimulated and the finger would quickly be withdrawn through a reflex arc. Use what you know about threshold potential and the all-or-none principle to explain different levels of sensation (light touch or pain)
Rapidly adapting tactile receptors include all the following types, except :-a- Merkel discsb- Meissner corpusclesc- Pacinian corpusclesd- hair end organs
Which statement about a center-surround receptive field is false? Select one: a. It can involve an inhibitory response (e.g., to touch) b. It is characterized by a circular center and a doughnut-shaped surround c. It is found only in primary sensory cortex d. It can be mapped by electrophysiological recording techniques e. It can involve an excitatory response (e.g., to touch)
Which statement about color perception theory is true? The mechanisms involved in opponent-process theory take place earlier in the perceptual process than those involved in trichromatic theory. The processes proposed by both trichromatic theory and opponent-process theory take place in the primary visual cortex. Trichromatic theory and opponent-process theory are both strongly supported by behavioral and physiological evidence. Recently, trichromatic theory has overtaken opponent-process theory as the best explanation of color and hue perception.
Which sensory processing principle listed below best explains why we detect heat sensation when eating foods that contain capsaicin, the molecule found in chili peppers. a. Parallel processing. b. Labeled lines. c. Topographic maps. d. Efferent modulation . e. Neural plasticity.
A pin can be pressed against the skin lightly and elicit no response from the pain receptor how ever, if this pain is jabbed into the finger, the pain receptor may be stimulated and the finger would quickly be withdrawn through a reflex arc. use what you know about threeshold potential and the all-or-none principle to explain different levels of sensation (light touch or pain)
We discussed three principles with regards to the sensory cortex (mechanisms of perception), with one of them being a hierarchical organization. Using the somatosensory system as an example (specifically the exteroceptive part of that system), state each level of the hierarchy with regards to this system, beginning with the one at the lowest level of the hierarchy to the final uppermost level. give the name at each level as it corresponds with this system.
Once initiated, the receptor potential :-a- spreads to a long distance along the sensory nerve fiberb- amplitude is not related to the strength of the stimulusc- always generates an action potential from the receptord- stays for a variable period depending on the type of the receptor
