front to back

top to bottom

breathing, heartbeat

controls primal urges:

• reproduction

  • sexual attraction

• huge in humans

• responsible for language

• memory/thought

• reasoning

top section of brain

middle section of brain

bottom section of brain

surgery done while the person is awake

measures brain waves/electrical activity in brain

• lets doctors see how brain is functioning

• based on how much glucose is in parts of brain

• glucose = brain fuel

• uses x-rays to take pics

• generates images of slices of brain

• uses magnets

• indicates certain activity/function/dysfunction in brain

• which areas are active during diff situations

• functional MRI

• what’s going on in brain

• where blood goes

• which parts of brain are active

• measures magnetic fields produced by electrical activity in brain

• runs reflexes

• size of pencil

• runs along center of back

• spinal tap- needle in spinal cord

• epidural drip- numbs pain

• encephalitis/meningitis- brain infection/brain membrane infected (really bad)

spinal cord damage:

• paraplegic- paralysis of legs

• quadriplegic- paralysis of arms and legs

• higher damage = worse

regulates:

• heartbeat

• respiration

• blood pressure

• in primitive core

• damage is very rare and fatal if done

• lack of motor control, numbness

• gamma knife

  • non invasive surgery

  • radiation to target part of brain

• relay neural signals from cerebrum + cerebellum to organs

• sleep wake cycle

• arousal level

  • and how quickly they happen

• Central pontine myelinolysis (CPM)

  • rapid increase of sodium to correct low sodium levels damages nerve cells (damages myelin)

  • in brain stem

• muscle control, balance, movement

• motor learning

• ataxia- muscle failure

  • vertigo

  • balance trouble

  • cell degeneration

• connects spinal cord to brain

• 12 diff pairs

• send electrical signals to head and neck

• bell palsy

  • sudden weakness/paralysis on one side face

• damage leads to loss of balance/facial expression

• levels of alertness

• behavioral arousal

• multitasking

• filters info

• whether or not smth gets transmitted

• sensory relay system

• visual, auditory, somatosensory, gustatory

• NOT SMELL

• perception of sensation

• emotion

• aphasia

  • loss of ability to understand/express speech

• apraxia

  • loss of movement/posture

• coordinating movement

• muscle tone

• controlling body movement

• parkinson’s + huntington’s disease

• coordination difficulty/movement

• eating/drinking/body temp

• emotion

• HOMEOSTASIS

• hypothyroidism

  • not enough hormones in thyroid

• fear/sadness/pain

• alzheimers- memory processing lost

• damage can affect fear response/fight or flight

• motivation

• reward

• reinforcement

• damage can lead to low engagement/lack of motivation

• transfer short-term memories into long term

• damage: amnesia/cognitive dysfunction

• limbic layer

• Broca’s area- language production

• motor cortex- signals to direct the movement of body

• prefrontal cortex- thoughts/actions/emotions thru connections w/other regions

• Broca’s area

  • french researcher

  • language production

  • Broca’s aphasia- can’t make words

• process auditory info

• encode memory

• long term memory

• auditory cortex- receive sound

• Wernicke’s area- speech comprehension

• Wernicke’s aphasia- impaired language comprehension

• self perception- aware of ur body

• sensory integration- sensory info from brain

• learned movements

• location awareness

• somatosensory cortex- sense of touch

• your brain controls the opposite side of the body

• language production

• logic

• sequences

• analytical

• controls left

• emotions, spatial abilities, faces, influences, self awareness

• controls the opposite field of vision

• left field, right brain

• right field, left brain

• 2 hemispheres do diff things- sight cannot be shared

• only 1 side can speak

brain damage

• natural/intentional

• prefrontal cortex

temporary loss of blood flow

bruising of the brain

lack of oxygen during birth

brain’s ability to change/reorganize

new neurons are generated

• connects the 2 hemispheres

• carry neural signals from one side to another

• coordinates physical movement

• process sensorimotor info

• sensory cohesion

damage:

• split brain- callosal syndrome

males- use mental map

females- landmarks

females

females

women- better multitaskers

male- focus on one thing

boys- banging + pushing

girls- asking for help

girls- better in math because it is more verbal in grade school

boys- get better at math as they grow

females

• glands, hormones, interact w/ the nervous system

  • some are mysterious

• “master gland”

• regulates all other glands in the body

• told what to do by the hypothalamus (homeostasis)

• puberty growth spurt (human growth hormone)

• learning, memory, cortisol (think like and adult)

• grain of rice, info from eye tells us when it’s dark

• adapts to surroundings, sleep, MELATONIN releases

• thyroxine, growth and metabolism (how quickly we burn energy)

• hyperthyroid: fast, eat whatever you want, graves disease

• hypothyroid: sleep problems, depression

• slows down w/age

• top of kidneys, makes EPINEPHRINE (adrenaline)

• stress- fight or flight

• glucosteroids- regulates

• makes insulin

• helps metabolize glucose, diabetes

• hyperglycemia- high glucose, needs insulin

• hypoglycemia- low glucose

• males- testes

• more androgens/testosterone (aggressiveness)

• females- ovaries

• estrogen
