Refer to the direct pathway of the basal ganglia. What part of the frontal cortex is targeted by the direct pathway? What are the effects of the direct pathway on the thalamus and frontal cortex? Explain the circuitry of the direct pathway. Begin with the inputs and end with its effect on the cortex.
Which is true regarding somatotopic organization?
Select one:
a. Certain areas of the body have much higher representation in the primary somatosensory cortex than other areas, and these regions will have finer tactile discrimination.
b. The representation of a given area of the body in the primary somatosensory cortex is directly proportional to the size of that body area (e.g., the right index finger has less representation than the right thigh).
c. The receptive fields for somatosensory neurons are circular and relatively consistent in size across areas of the body, but areas of the body with the finest tactile discrimination have many more neurons representing them in the primary somatosensory cortex.
d. There is equal representation of all areas of the body in the primary somatosensory cortex
Medical practice is paying more attention to theautonomic system in considering disease states. Whywould autonomic tone be important in consideringcardiovascular disease?

- What does the neuron composition of the dorsal root ganglion tell you about sensory coding in the somatosensory system? a. The large axon sizes have a slower conduction velocity than small axon sizes. b. The uniform axon sizes for all neurons indicate that they have the same conduction velocity. c. Multiple modalities or sensations can be detected from the skin. d. Only a single modality or sensation can be detected from the skin. e. Processing must occur directly in the skin since the neurons in the dorsal root ganglion are second order neurons.arrow_forwardNociceptors are pain receptors that respond to noxious stimuli, and send AP's to both the spinal cord and the brain.
