The conscious perception of pain is often delayed because of the time it takes for the sensations to reach the cerebral cortex. Why would this be the case based on propagation of the axon potential?
Following administration of an opiate drug, "pain signals" are prevented from getting out of the
spinal cord via two mechanisms. One inhibits spinal cord neurons that communicate with the
parafascicular nucleus of the thalamus. What is the other way that pain signals are stopped?
dendro-dendritic synapses that enhance IPSI's in somatosensory neurons.
the disinhibition of long axons that start in the spinal cord and influence free nerve endings directly.
O a feedback loop to the periaquedictal grey of the midbrain, which enhances neural activity in that area.
axo-axonic synapses that prevents somatosensory neurons from releasing neurotransmitter.
The thalamus has been described as a “switchboard.” Explain why, by describing the pathway of somatic sensory information from the receptors to the cerebral cortex.
Case Study:
Princess Leia has asthma, and had to use her inhaler before taking her physiology exam. Later, in the physiology laboratory, she measured her pulse rate and blood pressure and found them to be higher than usual. The following week, after administering some drugs (epinephrine, atropine) she later developed a severe headache and dry mouth. When she looked in the mirror she noticed that her pupils were dilated.
