Parts of The Brain

Psych SAC 2

QuestionAnswer
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)

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
