Q

cognitive neural processing

A

programming computers to act according to brain signals that have been monitored and recorded; has worked with planning and intention (pointing/reaching for something); might be a way to read thoughts for stroke patients and for paralytics/amputees to gain (artificial) motor control

A

uses electrodes; patient stares at motion, thinks of doing themselves, and does it w/o control

16
Q

Broca’s Area

A

in frontal lobe; production of language

17
Q

parietal lobes

A

sensory input for touch (pressure, pain) and body position; language processing; includes Wernicke’s Area and angular gyrus

18
Q

Wernicke’s Area

A

understanding language

19
Q

angular gyrus

A

converts words to sounds to send to Wernicke’s Area

20
Q

occipital lobe

A

receives info from visual cortex

21
Q

temporal lobes

A

auditory control (speech percetion); includes hippocampus -> memory; smell

22
Q

constraint-induced therapy

A

aims to rewire damaged (stroke maybe) brain by restraining functioning limb and forcing use of damaged one

23
Q

neurogenesis

A

production of new neurons; confirmed via Cold War bc of carbon-dated neurons from nuclear tests; 700 new daily and 2% annual turnover rate in hippocampus

24
Q

neural stem cells

A

can develop into any kind of brain cell; might be able to mass produce in lab and use with brain damage patients

25
Q

compensation/reassignment

A

when a condition/injury frees up brain areas normally restricted to certain functions that aren’t in use anymore

26
Q

corpus callosum

A

neural fibers thagt connecting hemis and carry messages between

27
Q

split brain

A

conditions resulting fro surgery that cuts fibers connecting hemispheres; left and right hemispheres act separately and are unable to know information that the other receives (“2 separate minds”)

28
Q

lateralization

A

right and left hemis serve different functions

29
Q

cotralateral

A

each hemi controls opposite side

30
Q

left hemisphere

A

analytical, linear, language, controls right

31
Q

right hemisphere

A

creative, intuitive, perceiving/expressing emotion, left side movements

32
Q

concussion; mild traumatic brain injury

A

blow to the head that can change how the brain works; brain hits skull and axons are teared/destroyed and release toxins; can affect memory, judgement, movement, speech, sleep; can cause anxiety/depression

33
Q

post concussion syndrome (PCS)

A

headaches, learning problems and behavioral symptoms months-years after injury

34
Q

sub-concussive impacts

A

less intense head blows that can lead to severe degeneration if repetitive (CTE); “fray” axons

35
Q

diffusion tensor imaging

A

shows large axon bubbles and how mild blows structurally alter them

36
Q

Chronic Traumatic Encephalopathy (CTE)

A

brain disorder caused by repetitive hits to head that can affect mood, behavior, thinking, and mem; 30-40 y/o; can result in dementia

37
Q

tau

A

protein that supports microtubules in axons that clump together when microtubules are damaged causing disrupted transport and communication across neuron and more clumps
