Psych SAC 2
Question | Answer |
---|---|
Describe MRI Scans | magnetic radio fields - structural |
Describe CT Scans | x-rays - structural |
Describe PET Scans | radioactive glucose, coloured images - functional |
Describe FMRI Scans | traces oxygen levels in brain, coloured images- functional |
Describe the location and roles in behaviour and mental processes of the cerebellum | Hind brain - coordination of movement |
Describe the location and roles in behaviour and mental processes of the medulla | Hind brain - vital processes eg breathing, heart rate |
Describe the location and roles in behaviour and mental processes of the pons | Hind brain - sleep and awareness |
Describe the location and roles in behaviour and mental processes of the reticular formation | Midbrain - filters and relays info between hind and fore brain |
Describe the location and roles in behaviour and mental processes of the hypothalamus | Forebrain - regulate internal body processes |
Describe the location and roles in behaviour and mental processes of the thalamus | Forebrain - info from organs and distributes sensory issues |
Describe the location and roles in behaviour and mental processes of the cerebrum | Forebrain - memory, learning and thinking |
Name and locate the Premotor cortex | in front of primary motor cortex - frontal lobe |
Name and locate the Primary motor cortex | left stripe - frontal lobe , left hem? |
Name and locate the Somatosensory cortex | right stripe (homunculus) - parietal lobe |
Name and locate the Primary auditory cortex | Temporal lobe, above Wernickes |
Name and locate the Wernicke’s area | Temporal lobe, below primary auditory cortex - left hem |
Name the areas of the brain involved in the processing of complex sensory information, | PAC - temporal primary somatosensory cortex - parietal PVC - occipital |
Name the areas of the brain involved in the initiation of voluntary movements | prefrontal cortex, premotor cortex, primary motor cortex - frontal lobe |
Name the areas of the brain involved in language | Wernickes area - temporal lobe Broca's area - frontal lobe PVC - occipital lobe |
Name the areas of the brain involved in symbolic thinking | prefrontal cortex - frontal lobe |
Name the areas of the brain involved in the regulation of emotion | prefrontal cortex - frontal lobe temporal lobe |
Explain the effects of split brain surgery | Severs corpus callosum, stops two hemispheres from communicating |
Explain the role of the somatosensory cortex and how the homunculus helps us to understand its organisation | receives and processes sensations eg touch. Homunculus: more area allocated, more sensetive |
List, in order, and describe the role of the areas of the brain involved in verbally responding to spoken words | T - PAC - hears words T - Wernickes area - interprets words T - Wernickes area - choose correct words to say F - Broca's area - produce sound, muscle control F - Broca's area - Apply correct grammar F - PMC - movement of muscle involved in speech |
Discuss the effect of damage to the cerebral cortex in terms of, including biological, psychological and social changes to the Prefrontal cortex (Phineas Gage) | An injury to the prefrontal cortex can cause problems with complex cognitive skills, personality, and behaviour |
Discuss the effect of damage to the cerebral cortex in terms of, including biological, psychological and social changes to the Broca’s area (Sarah Scott) | Loss of speech production (they are unable to translate their mental images and representations to words) |
Discuss the effect of damage to the cerebral cortex in terms of, including biological, psychological and social changes to the Wernicke’s area (sufferers of Wernicke's aphasia) | Loss of speech comprehension. (Despite this impaired comprehension, speech may have a normal rate, rhythm, and grammar) |
Structural vs functional | structural: looks like functional: activity |
