Question

14. (lecture) Draw a simple diagram indicating the location and major functions of the following cortical areas: lobes (4), visual cortex, auditory cortex, motor cortex, somatosensory cortex, prefrontal cortex. 15. Draw a simple diagram indicating the location and functions of the following structures: basal ganglia, limbic system (amygdala, hippocampus, olfactory bulb), thalamus and hypothalamus. 6. Draw a simple diagram indicating the location and functions of the 17 what is a “stroke?" Describe the symptoms and the cause of 8. Know the identifying characteristics of techniques to visualize the following brainstem structures: cerebellum, pons, medulla damage to neurons brain structures and activity: CAT scan, MRI, functional MRI (fMRI), PET (positron emission tomography), TMS (transcranial magnetic stimulation), and MEG (magnetoencephalography) Distinguish whether the technique measures structure or function.

Explanation / Answer

Frontal lobe

Postcentral gyrus.

Parietal lobe.

Cortical areas Location Function

Frontal lobe

Located at the front of the brain. Emotional expression, memory, problem olving etc. Parietal lobe located above the occipital lobe and behind the frontal lobe and central sulcus. Language processing. Temporal lobe Beneath the lateral fissure on both the cerebral hemispheres. Primary auditory perception, language an speech production. Occipital lobe Medial surface of the left cerebral hemisphere. Visual processing center. Visual cortex Around the calcarine fissure in the occipital lobe. To process impulses generated from optic nerve. Auditory Cortex Temporal lobe; on the superior temporal gyrus. Reciever ofinput from medial geniculate complex; processes auditory information. Functions in hearing. Motor Cortex Frontal lobe; along precentral gyrus. Control of voluntary movements. Somatosensory cortex

Postcentral gyrus.

Parietal lobe.

Sensory receptor. Processes input from neurons that sense feelings in our skin. Pre frontal cortex Front part of frontal lobe. Control of decision making, cognitive behaviour, personality expression.
