Damage to the medulla can produce problems in regulation of respiration. regulation of sleep. filtering of sensory information. motor coordination. a. b. c. d. 3. A cut through the brain that divides the two hemispheres (a cut "between the eyes") is called a section. a. sagittal b. coronal c. horizontal d. superior 4. The basal ganglia are important for a. b. c. d. processing visual information. processing auditory information. directing attention. regulating movement. 5·The reticular formation is a network of neurons in the brain that a. b. c. d. controls respiration. regulates blood pressure. processes odor information. can cause you to pay attention to a new sound. 6. Epileptics experiencing intense emotions instead of convulsions may be having a seizure. a. limbic system b. basal ganglia c. reticular formation d. cerebellar 7. The misfortune of Phineas Gage helped illuminate the function of the a. parietal lobe. b. temporal lobe. c. frontal lobe. d. occipital lobe.Explanation / Answer
1.Loss of myelin from neurons would be expected to greatly impair neuronal conduction.
2.filtering of sensory information.You may lose your sense of touch, develop vertigo or have trouble swallowing. You may not be able to sense or detect pain and temperature changes.
3.Sagittal section.The sagittal plane divides the right and left side of the brain into parts.
4.regulating movement.The basal ganglia, also known as basal nuclei, is a region on the underside of the brain that plays a very important role in muscle coordination and movement.
5.Can cause you to pay attention to a new sound. It is responsible for stereotyped patterns such as walking, sleeping, or turning to attend to a sudden noise
6.Limbic system seizures.Psychic seizure can cause sudden and often intense emotions such as fear, anxiety, depression, or happiness
7.Frontal lobe.The model also indicates that the accident damaged the connections between the frontal cortex to the limbic system, which are involved in the regulation of emotions.
