- Julio D., who had recently retired, was enjoying an afternoon of playing golf when suddenly he experienced a severe headache and dizziness. These symptoms were quickly followed by numbness and partial paralysis on the tipper right side of his body, accompanied by an inability to speak. After being rushed to the emergency room, Julio was diagnosed as having suffered a stroke. Given the observed neurological impairment, what areas of his brain were affected?Higher motor commands originate in all the following centers, except :-a- cerebral cortexb- thalamusc- caudate nucleusd- cerebellumYou are walking to class, pondering the intricacies of physiology, when you trip over an uneven place in the sidewalk and fall. Unhurt but embarrassed and angry, you jump up and glance around to see if anyone is watching. From your knowledge of neuroanatomy and function, explain how the following areas of the brain might be involved in this scenario: cerebrum cerebellum limbic system
- All of the following are associated with control of automatic functions except:a. limbic systemb. cerebral cortexc. hindbraind. medulla oblongataWatch this video (http://openstaxcollege.org/l/ 3Dmovies) to learn about the side effects of 3-D movies. As discussed in this video, movies that are shot in 3-D can cause motion sickness, which elicits the autonomic symptoms of nausea and sweating. The disconnection between the perceived motion on the screen and the lack of any change in equilibrium stimulates these symptoms. Why do you think sitting close to the screen or right in the middle of the theater makes motion sickness during a 3-D movie worse?All of the following are true regarding the descending motor tracts EXCEPT which one? A. They originate in either the cerebral cortex or brainstem. B. The pathways are generally made of a two-neuron system. C. The upper motor neuron fibers target lower motor neurons of the spinal cord or cranial nerves. D. They are involved in assisting with voluntary movement.
- Neurones of the lateral corticospinal tract: Select one: a. travel through the dorsal part (white matter) of the spinal cord b. are responsible for receiving sensory information and sending it to the brain travel down the lateral horn (grey matter) d. are capable of relaying afferent and efferent information decussate in the brainstem C. e.The area of the brain that is involved in balance and fine-tuning movements is the cerebral cortex thalamus infundibulum cerebellumHuntington’s disease causes too much ballistic movement due to which of the following reasons? Group of answer choices Loss of the inhibitory connection between the striatum and the globus pallidus external Loss of the inhibitory connection between the striatum and the globus pallidus internal Loss of the inhibitory connection between the globus pallidus external and the globus pallidus internal Increased activity of globus pallidus internal neurons
- Neuroscience Basal Ganglia and Cerebellum 1) Describe the basic anatomy of the basal ganglia and cerebellar circuits and theirrole in the refinement of movement 2) Know the basic anatomy of these structures and list the inputs to the basal ganglia Please provide pictures with your explanation. This should help me prepare for an upcoming exam. I need to understand what is going and I'm a visual person!!Help me label these terms correctly -premotor cortex -superior temporal gyrus -lateral sulcus -inferior temporal gyrus -central sulcus -middle temporal gyrus -somatosenory cortex -primary motor cortex -supplementary motor areaThe posteroventral nucleus of the thalamus projects to all the following centers, except :-a- frontal motor areasb- primary somatic sensory areac- somatic sensory association aread- parieto-occipito-temporal association area
