| Question | Answer |
|---|---|
| eugenics | improving the genetic quality of a person by controlling reproduction (like selective breeding for dogs) |
| hippocampus | forming and storing new memories |
| pineal gland | sleeping cycles |
| all or nothing principle | once a neuron has enough threshold strength, it will "fire" an action potential with all of its energy. this is like pulling the trigger on a gun (bad ex ik) |
| depolorization | -inside less negative/more positive -outside more negative/less positive -like a dam breaking through, letting all of the water in |
| refactory period | short period of time when a neuron cannot generate an action potential, so it is "resting" |
| multiple sclerosis (ms) | disease that effects the CNS by attacking the mylien sheath of the axon |
| myasthenia gravis | disease where the receptors are blocked so the neurotransmitters cannot bind. dec muscle movement bc no reception occurs |
| glutamate | learning, memory, and brain plasticity over - migraines, seizures |
| GABA | relaxation and reduces anxiety under - seizures, tremors, insomia |
| serotonin | mood, emotional stabilty under - depression |
| endorphins | pain and mood enhancers |
| substance p | transmits pain signals over - chronic pain |
| acetylcholine | -parasympathetic/rest and digest/slows down -alzhiemers |
| ghrelin | appetite and hunger (ghr = growl = stomache growls when you are hungry) |
| leptin | energy balance |
| oxytocin | social bonding and love |
| norepinephrine | sympathetic/fight or flight/speeds up under - dec mood |
| epilepsy | -seizures -split brain can help the seizures from not spreading/occuring from both sides of the brain (does not solve but def helps) |
| pons | sensory info, breathing, sleep |
| medulla | heart rate and breathing |
| genetic predisposition | change of getting condition/disease bc of genes |
| Somatosensory cortex | touch and sensation only (part of sensory cortex but more specific) recieves info that moving legs |
| epigenetics | how enviroment or behaviors can change how the genes work (turning them on or off) w/o changing the dna itself |
| hindbrain: | -medulla -pons -cerebellum |
| midbrain: | reticular formation (waking up and sleeping) |
| forebrain: | -thalmus -hypothamus -hippocampus -amyglada aka limbic system (HAH) + Thalmus |
| phrenology | bumps in brain can show chracteristics of person - FALSE tho |
| types of scans that show only structure | -MRI (anatomy) -CT scan |
| types of scans that show only function/activity | -fMRI (function) -PET scan (activity) -EEG |
| enviroment has ______ effect on characteristics | little (has to do mostly w/ genes) |
| dopamine over and under | over - schinzophrenia under - tremor, parkingtons |
| cerebellum | motor |
| humans have larger ______ | forebrain |
| assosiation areas | Anticipating |
| sensory | out --> brain (in) aka Sending messages |
| motor | in (brain) --> out aka Make the move |
| interneuron | in (brain) --> in (brain) ex: reflex |
| pet scan | mapping specific areas. fmri can replace |
| fmri | change in blood bc of pain |
| eeg | WHEN something happens |
| ct | FAST x ray, less detailed mri scan |
| mri | SLOW, more detailed ct scan |
| nature ____ nuture | via |
| lateralization | one side vs other only |
| parkingsons | dec movement |
