A)Pre-central gyrus B)Post-central gyrus C)Pre-frontal lobe D)Wernicke’s area E)Basal Nuclei Answer A 3 Which part of the brain would receive stimuli from the spinothalamic tract? A)pre-central gyrus B)Post-central gyrus C)Pre-frontal lobe D)Wernicke’s area E)Basal Nuclei Answer B 4 Which part of the brain would connect to both auditory areas and Broca’s area? A)Pre-central gyrus B)Post-central gyrus C)Pre-frontal lobe D)Wernicke’s area E)Basal Nuclei Answer D 5 Language Pathways Listening: Speaking: Visual or auditory cortex Wernicke’s area Broca’s area Motor cortex Wernicke’s area is, among other things, the center for language use. It processes input from both visual and auditory sources (reading language and hearing speech) and sends stimuli to Broca’s area and the motor cortex for speech production. 6 Too much dopamine, or malformation of which part is believed to be a cause of schizophrenia? A)Pre-central gyrus B)Post-central gyrus C)Pre-frontal lobe D)Wernicke’s area E)Basal Nuclei Answer C 7 Lack of dopamine secreted into the _____ is the cause of Parkinson’s?

Its structures include the caudate nucleus, putamen, and globus pallidus, and by some authors the substantia nigra and amygdaloid nucleus. (Marieb considers the substant...
