- The ____ and ____ are both found deep within fissures of the cerebral cortex. These two regions form a network with the amygdala and hypothalamus. Although they are also involved in other important functions, many modern imaging studies show that they activate simultaneously during the conscious experience of emotional feelings. A) anterior cingulate cortex; anterior insular cortex B) thalamus; hippocampus C) caudate nucleus; globus pallidus D) substancia nigra; ventra tegmental areaResearch suggests that PGO waves play an important role in generating REM sleep. PGO waves activate all of the following brain regions EXCEPT: A) the occipital lobes. B) the pons. C) the prefrontal cortex. D) the lateral geniculate nucleus.Which of the following is True and which of the following is false: 1) Psychoactive drugs rarely provoke a response by the area postrema due to their ability to cross the blood-brain barrier easily. 2) George weighs 200 lbs and Marcy weighs 120 lbs. Both are sadly opioid addicts. If they both inject the same amount of heroin, they will likely have similar experiences because the amount of blood you have is not related to your weight. 3) Drugs that are addictive always produce tolerance and withdrawal. 4) Symptoms of withdrawal are usually the opposite of the effects of the previously used drug. 5) Although their main effects occur in other neurochemical systems, both MDMA (Ecstasy) and cannabis distort the activity of dopamine, suggesting that these drugs have the potential to be addictive. 6) Opioids produce most of their effects by enhancing the release of a variety of neurochemicals from presynaptic axon terminals. 6) Dr. Baskin is studying the heritability of aggressiveness in…

Ventral horn Dorsal root ganglia Dorsal horn Thalamus Medulla Identify the location of the cell bodies of first order neurons of the spinothalamic tract? Ventral horn Dorsal root ganglia Dorsal horn Thalamus MedullaFollowing a stroke Dr. Z was unable to recognize the members of his family when shown their portrait. It was different when he was in their physical presence, because then if he heard them speak or saw them move in particular ways he could identify them. Where is the most likely site of brain damage? Question 3 options: A) Ventral pathway from V1 to the fusiform gyrus B) Ventral pathway from V1 to amygdala C) Dorsal pathway from V1 to motor cortex D) Primary visual (V1) cortexYou are trying to explain the ventricular system of the brain to your younger sister. You tell her the following: Cerebrospinal fluid (CSF) is formed as a filtrate of blood at the level of a choroid plexus. It passes through ependymal cells to the space between the arachnid mater and pia mater. Once it has traveled around the periphery of the brain within this space between those two meninges, the CSF then accumulates in the third ventricle. Once there, it passes to the fourth ventricle via the cerebral aqueduct and then travels via the central canal to the spinal cord. It is finally reabsorbed by the arachnoid granulations. The cerebrospinal fluid is turned over about three times every 24 hours. What error did you make in this description? Practice g• 6S: The CSF travels from the third ventricle to the fourth ventricle via the cerebral aqueduct When being formed it has to pass through ependymal cells The CSF is reabsorbed by arachnoid granulations The CSF travels from the subarachnoid…
- List the functions of the hypothalamus and indicate the other brain regions that cooperatewith the hypothalamus in the performance of these functions.The limbic system is composed of several interconnected structures including the olfactory bulbs, amygdala, hypothalamus, hippocampus, parahippocampal gyrus, cingulate gyrus, subcallosal gyrus, septal nuclei, mammillary bodies, and the thalamus. Pair each of these structures with their function listed below: -This limbic area is active when you are trying to memorize the names of brain areas. It is also severely atrophied in people suffering from late stages of Alzheimer’s Disease. -This limbic area is active when you are watching something that makes you feel sad. -This limbic area is active when you feel thirsty. -When the activity of this limbic area is increased you feel a sense of pleasure. -When this limbic area is damaged it often results in patients experiencing anterograde amnesia. -Damage to this limbic structure while rare often results in patients going into a coma. -This cortical limbic structure plays a large role in motivation and movement and has recently been…All of the following are functions of the hypothalamus except a. controls endocrine system. b. regulates sleep-wake cycle. c. controls autonomic nervous system. d. initiates voluntary skeletal muscle movement.
