5.2 - Structure of the Brain Flashcards
(19 cards)
the role of the cerebral cortex
5.2
- receiving information from the environment
- controlling out responses
- higher order thinking processes (e.g. problem solving and planning)
5.2
structure of cerebral cortex
5.2
- thin
- convolutions make surface large enough to contain a large number of naurons and blood vessels that can supply energy
- bulges known as gyri (gyrus singular)
- valleys called sulci (sulcus singular)
5.2
lobes of the cerebral cortex
5.2
- frontal lobe
- parietal lobe
- occipital lobe
- temporal lobe
5.2
purpose of
broca’s area
5.2
speech and grammar
5.2
purpose of
frontal lobe
5.2
abstract thought, social skills, and planning
5.2
purpose of
temporal lobe
5.2
hearing, language, visual recognition
5.2
purpose of
parietal lobe
5.2
touch, non-verbal thought, spatial orientation
5.2
purpose of
occipital lobe
5.2
vision
5.2
purpose of
wernicke’s area
5.2
comprehension of language
5.2
primary cortices
5.2
when first recieve information, it is sent to the thalamus and it relays to the primary corex of the relevant lobe
5.2
primary visual cortex
5.2
receives visual information from the eyes
5.2
primary auditory context
5.2
receives sound information from the ears
5.2
primary somatosensory cortex
5.2
receives information from touch receptors on the skin
5.2
primary motor cortex
5.2
controls movements
5.2
role in cognitive process
frontal lobe
5.2
functions: initiating movement of the body, language, planning, judgement, problem-solving, aspects of personality, and regulation of emotions
5.2
damage
frontal lobe
5.2
- difficulty learning from experiences (preseverating)
- make mistakes in planning because lack of foresight
5.2
role in cognitive process
parietal lobe
5.2
function: receives sensations (touch, pressure, temperature, and pain)
5.2
damage
parietal lobe
5.2
- unable to process sensation from parts of the body on the left side
- relevant body part will be numb
5.2
temporal lobe
