-we sleep so our body can file away the thoughts of the day. The overall goal is to recuperate neurons in the brain
-the sleep cycle is 90 minutes
-the order is 1 2 3 4 3 2 1 REM
-best stage to wake up in is 1
-another word for rem is paradoxical sleep
-hypnagogic sensations is when you feel like your falling while sleeping
-the manifest is the content of your dream and latent is the meaning behind it
-why is it that we dont remember our dreams?

-corpus collosum allows the two hemispheres to communicate to one another
-the sensory and motor cortex work with the brain and the rest of the body to communicate to each other. If you see something with your left then it will be comprehended by the right and vice versa

what does it mean to be human?
-although biologically, humans have very different characteristics than other species, being human involves the brain processes that other organisms do not have. Furthermore, being humans includes communication and individuality. Humans have control over their decisions.

Exploring the mind:
-How does the findings of Jim's scan and the mind reading discovery help answer theoretical questions in ways that existing measures cannot?
-----

Hindbrain: earliest to evolve
-medulla: breathing, heart rate
-pons: sleep/wake cycle; facial recognition
-cerebellum: balance, coordination
-brain stem: connects spinal cord
-REticular formation: bundle of nuerons in hind mid and part of forebrain -- sends alert signals, filters incoming stimuli, helps control arousal, if damaged coma

Midbrain: sensory information
-emotion and pain

Forebrain: Thinking, reasoning, what makes us human
-collection of upper-level brain structures, including the thalamus, hypothalamus, and limbic system
-Cerebrum/cerebral cortex: 2 hemispheres highly developed in humans, convulations: sensations, motor control, and higher mental processes
-thalamus: directs sensory messages
-hypothalamus: life functions- breathing, sleeping, hunger, thirst, sex
-corpus callosum: threadlike connections between hemispheres
Limbic system: interconnected group of forebrain structures involved with amygdala, hypothalamus, and hippcampus
------amygdala: fear and aggression
------hypothalamus: survival needs
------Hippocampus:new memories

-sensory cortex: in front of pariental lobe, deals with senses, more sensitive is greater area
-motor cortex: in back of frontal lobe, movement, more agile=more area

Types of neurotransmitters
-Acetylcholine (ach)
-excitatory
-movement, arousal, attention, and memory
-too much:spasms
-too little: paralysis
-Dopamine
-inhibitory or excitatory
-emotions, pleasure, involuntary movements
-too much: schizophrenia
-too little: parkinson's
-Serotonin
-inhibitory
-activity levels, sleep mood, eating
-too much: euphoria, muscle twitching
-too little: sleeplessness, depression
Norepinephrine
-excitatory
-arousal, wakefulness, memory
-too much: arousal and anxiety
-too little: memory impairment, depression
Endorphines
-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 or seizures
*when ready to fire, it polarizes, when it fires it depolarizes

Agonist Molecule
-mimics a neurotransmitter, fitting into the receptor site and exciting the site.
Antagonist Molecule
-fits into the receptor site but is not similar enough to stimulate it. Instead, it blocks or inhibits the function of that receptor.
