Resting: -70mV Local potential: -68mV Threshold: -55mV Charged: +35mV |
|
|
Term
|
Definition
After Na+ pump pushes out excess the resting membrane potential returns to resting, or a bit below |
|
|
Term
Action Potential Speed: Myelinated vs Non-Myelinated |
|
Definition
|
|
Term
|
Definition
Gaps in myelin sheath; ion channels cluster here |
|
|
Term
|
Definition
skip/jump; like the action potention with the myelination |
|
|
Term
Stimulatory/excitatory synapses |
|
Definition
nt binding causes post-synaptic cell to be depolarized: na influx ca influx, more positive ions enter so new AP is generated |
|
|
Term
|
Definition
Nt binding causes post-synaptic cell to be hyperpolarized cl-influx, k+ efflux |
|
|
Term
|
Definition
genes coding for new synapses are expressed when synapses are repeatedly fired |
|
|
Term
|
Definition
tight junctions between capillary endothelial cells, stimulated to form by astrocytes (glial cells). Protects brain by keeping many large molecules in blood, and away from neurons |
|
|
Term
|
Definition
primary motor cortex, motor association area, Broca's motor/expressive speech/language area, prefrontal cortex |
|
|
Term
|
Definition
(Frontal lobe) motor plans and programs; motor memory - hard drive for motor skills |
|
|
Term
Broca's motor/expressive speech area |
|
Definition
language region responsible for expressive language, allows you to produce speech. (Frontal lobe, left hemisphere) |
|
|
Term
|
Definition
thinking, planning, problem-solving, impulse control, executive function, working memory, inner adult |
|
|
Term
|
Definition
Behind frontal lobe:primary somatosensory cortex, somatosensory association cotex, parieto-temporal association cortex |
|
|
Term
Primary somatosensory cortex |
|
Definition
perception of somatosensation from body and face: pain, temperature, pressure, position sense |
|
|
Term
Somatosensory association cortex |
|
Definition
interprets somatosensory information = stereognosis: body part ownership and body image |
|
|
Term
Parieto-temporal association cortex |
|
Definition
abstract thought, reading, writing, mathematics ; connects to temporal lobe |
|
|
Term

|
|
Term
Wernicke's sensory (receptive) speech area |
|
Definition
understanding of speech and language, usually in left hemisphere |
|
|
Term
|
Definition
overlaps frontal, parietal, temporal. Responsible for emotions, preferences, personality, memory. Who you are as a person |
|
|
Term
|
Definition
protects us from danger; responsible fro strong negative emotions: fear, rage/anger, disgust, shame |
|
|
Term
|
Definition
formation of longterm memories: learning; right hippo is spatial, left hippo is verbal |
|
|
Term
|
Definition
sensory processing, connects sensation to emotion and thought (diencephalon) |
|
|
Term

|
|
Term
|
Definition
folds, contain spaces. Dural sinuses contain venous blood from the brain |
|
|
Term
|
Definition
provides redundancy; blood to all parts of cortex via cerebral arteries; little overlap |
