Mark the following statements on the role of the brain in movement as true or false. If a statement is false, correct it to make a true statement. a. The dopaminergic neurons of the substantia nigra enhance the actions of the caudate nucleus and putamen. b. The cerebellum monitors the initiation of movement but does not monitor ongoing movements. c. The basal nuclei inhibit inappropriate movements and are required for the initiation of movement. d. The correction of motor error by the cerebellum can occur over the long term by motor learning
What role do basal nuclei play in the regulation of muscle tone? In Parkinson's disease, neurons involved in motor commands die off. What are some characteristics of an individual with Parkinson's disease? What neurotransmitter's concentration declines in the basal nuclei as a result of the loss of these neurons? How is muscle tone affected by the decline in this neurotransmitter? How is Parkinson's disease treated? What does it mean that the thalamus is a "relay station"? The thalamus and basal nuclei have completely opposite effects on muscle tone. Can you explain this contrast? If pain were sensed in the thalamus, would there be any indication of where it's coming from? How could this emphasize the importance of the parietal lobe? The thalamus works by filtering 98% of sensory information. Given your knowledge of neurons, how do you think the thalamus "filters out" this information? How could an impairment in the thalamus' filtering capacity of sensory information lead to the symptoms seen in attention deficit hyperactivity disorder (ADHD)?
