Nearly all regions of the cerebral cortex Downloaded by Nat Kp ([email protected]) lOMoARcPSD|2850388 Answer: e Textbook Reference: Projections to the Basal Ganglia Bloom’s Level: 1. Remembering 5. Refer to the figure. Which region of the basal ganglia is indicated by the asterisk? a. Striatum b. Pallidum c. Globus pallidus d. Substantia nigra pars compacta e. Subthalamic nucleus Answer: c Textbook Reference: Projections to the Basal Ganglia Bloom’s Level: 4. Analyzing 6. What evidence suggests that medium spiny neurons are associated with a decision to move? a. Cortical areas concerned with the hand converge in a different striatum area than cortical areas concerned with the leg. b. Neurons in the putamen and caudate discharge seconds before the initiation of movement. c. The more extensively interconnected the area of cortex, the greater the overlap in their projections to the striatum. d. Staining of the striatum reveals patches surrounded by matrix. e. Input and output into the different components of the striatum is unique. Answer: b Textbook Reference: Projections to the Basal Ganglia Bloom’s Level: 4. Analyzing 7.
