...practice diagram quiz and break down sleep stages

# data[].attributes.body
1- wakefulness to sleepiness ( HR goes down)

2- onset of sleep (Body temp drops, sleep spindles-short burst of brain activity begin)

3- muscles relax, body rejuvenates (pituitary gland releases hormones for growth, delta waves)

4- sleep walking/talking potential( delta waves get longer in stage 4)

REM- rapid eye movements, HR increases, dreaming begins

90 min cycles

manifest/ latent content- dream/ meaning of dream

activation synthesis theory- brain trying to make sense of activity during sleep

psychotherapeutic theory- mind trying to resolve any problems or heal any emotional trauma collected throughout concious moments

...Explan the difference between the 2 hemispheres & begin sleep

# data[].attributes.body
-sleep to help growth, clarify/recharge brain,
-full rem sleep is the deepest stage of sleep.. muscles relaxed, body paralyzed except
sleep cycle=90 minutes
full sleep cycle: 1 2 3 4 3 2 1 REM
REM cycle is longer with longer hours of sleep
best to wake up at stage 1
stage 3 and 4 go away at 5 and 4 hours of sleep
sleep deprivation linked to depression and weight gain
sleep apnea: stop breathing in sleep until they wake up
night terrors: common in children.. occur during stage 3
we dream in paradoxical sleep- almost paralyzed
manifest content: what happened in dream
latent content: what is soppsed meaning of dream

...understand a split brain person (Gazzaniga- researcher)

# data[].attributes.body
corpus callosum- connects 2 hemispheres of brain for connection

severed for split brain procedure to prevent epileptic seizures

L hemisphere

controls R side of body

ability to speak if shown images to right eye

puts explanation in words to understand everyday occurences

analytical, logical

R hemisphere controls L side of body

nonverbal communication (ex: draw a pic, point )

cannot put words to images shown to R side

facial recognition; expression, familiarity

abstract, artistic

I would rather live without my left hemisphere because things would get boring if I could only think of logic

...understand the endocrine system and the influence of drugs on the body 

# data[].attributes.body
endocrine system: releases hormones based on what materials found in blood to control growth and development

pituitary, pancreas, adrenal, thyroid, hypothalamus, reproductive, parathyroid

affects of drugs

meth: replaces dopamine in receptors and overloads nerve with pleasure- highly addictive

alcohol: reacts with inhibitory GABA n.t.'s to heighten effefts and prevents glutamate from being reuptaken by cell which stops the cell from being excited... mainly effects frontal lobe( decion making, impulse control, memory)

ectstasy: confuses seratonin receptors and transports seratonin out of receptors and replaces it wiht ecstast which mimics the nuerotransmitter... seratonin gets trapped in synaptic gap adn overstimilates the cell

heroin: brain releases opiates if inhibators are turned off.. heroin beinds to opiate reepts which turns the inhibators off and floods brain with feeligs of sedation and well beng

cocaine: binds to dopamine receptors which makes dopamine bind to cell repetedly for high

LSD: binds seratonin to receptors.. acts as seratonin and sometimes inhibits receptors sometimes excites

marijuana: cannaninnoid receptors turn off release of inibiroty n.t.'s, thc mimics anandamide to turn off and release dopamine for high

REFLECTION: using evidence for the function of the frontal lobe, explain in 3 sentences or more, what is means to be human

# data[].attributes.body
The frontal lobe, from a scientifical perspective, allows the person to have a personality and use their logic to problem solve. Due to this fact, it can be found evident in each individual that the processing of experiences is customized by each individual. While we all function the same on a physiological level, the way our frontal lobe allows us to view and see our world is defining point for what makes us human. Having the free will to act on the ideas we derive from the world around us, creating motives that go deeper than pure survival instinct , differentiates humans from the rest of the animal world.

...identify the different parts of the brain 

# data[].attributes.body
cerebrum- thinking, motor control, sensations
cerebellum- balance/coordination
pons- sleep/wake cycle, facial recognition
medulla- HR, Breathing
reticular formation- send alerts, filters stimuli, helps control arousal
thalamus- directs sensory messages
hypothalamus- fullness, hunger, thirst, survival functions
corpus callosum- connects 2 halves of brain to each other
hippocampus- memory
pituatary gland- hormones for growth
amygdala-fear/aggression
frontal- personality, logic, problem-solving
parietal- touch, sensory
temporal- hearing
occipital- visual processing
brokas- speech
wernickes- listening
motor cortex- motor functions
sensory cortex- sensory functions
hindbrain- oldest part- survival instincts (medulla, pons, cerebellum)
midbrain- sensations, emotion, pain
forebrain- thinking, reasoning( thalamus, hypothalamus, amygdala, hippocampus, pituatary, corpus callosum)

...identify the different types of neurotransmitters & be ready for the quiz tomorrow 

# data[].attributes.body
acetylcholine (Ach): *excitatory *movement *arousal *attention *memory -too much: spasms -too little: paralysis

dopamine: *inhibatory or excitatory *emotions and pleasure, involuntary movements -too much:Schizophrenia -too little: Parkinson's

Seratonin: inhibitory *activity levels, sleep, mood, eating -too much: euphoria, muscle twitching - too little: sleeplessness, depression

SSRI (selective seratonin reuptake inhibator)- inhibits the reuptake of seratonin - to reverse depression to stop reuptake

nonrepinephrine: *excitatory *arousal, alertness wakefulness, learning, memory -too much:arousal and anxiety -too little:f memory, inpairment, depression

Endorphins: *inhibitory *inhibits pain message -too much: no pain too little: increase in pain

GABA (gamma amino-butyric Acid): *inhibits neurons from firing *increases sleep and relaxation -too much: shortness of breath -too little: anxiety/ seizures

agonists: mimics neurotransmitter- fits into the receptor site and excites the site (morphine mimicking endorphins)

antagonists: fits into site but doesn't stimulate receptor site instead it blocks the function of receptor (botulin)

I can discuss the nature vs. nurture debate in the biological perspective 

# data[].attributes.body
Biological perspective-
-inherited genes determine likeliness for certain behaviors and diseases
ex: in a study rats that developed an addiction for alcohol, later had offspring that were more prone to the same issue
-the different parts of the brain have different functions, if they do not function properly it will lead to disorders

# data[].attributes.body
*BIO- correlation with similar behaviors in family members due to genetics
* environmental- influneces in environment expose people to addictive stimuli; friends introduce, sights/sounds/smells that bring out urge, people who are dominated by others in society are more likely to use
*behavioral- positive reinforcement (feeling good after use), primary reinforcer because it directly strengthens behavior, negative reinforcement( sickness after drugs will usually link to lessening of use)
