|
Cerebrum |
Contains the cerebral cortex and the limbus system |
|
|
|
Cerebral Cortex |
2 hemispheres; 4 lobes Responsible for thinking, perception, & memory |
Spaghetti looking part of brain |
|
|
Limbic System |
Most primitive part of forebrain Responsible for memory formation and emotions |
Responsible for the 4 'F's -feeding, fighting, fleeing, reproducing |
|
|
Left hemisphere |
Logic, analysis, math, facts, language, sequencing, words of a song/tune
Controls right side |
|
|
|
Right hemisphere |
Creativity, arts (motor), non verbal, imagination, intuition, rhythm, tune of a song
Controls left side |
|
|
|
Frontal lobe |
Inhibition/disinhibition, problem solving, attention, cognitive switching, motivation
ADHD |
|
|
|
Temporal lobe |
Primary auditory and language area Aphasia -Broca (frontal lobe damage) -semantics good, fluency bad -Wernicke (temporal lobe damage) -fluency good, semantics bad |
|
|
|
Amagdyla |
Fear, excitement, & arousal Damage: inability to perceive danger & PTSD |
|
|
|
Hippocampus |
Spatial memory |
|
|
|
Anterograde amnesia |
Inability to make memories |
|
|
|
Retrograde amnesia |
Inability to recall old memories |
|
|
|
Parietal lobe |
Perceive motion, ability to know where things are and how to grab them, special reasoning, sensory Damage: facial discrimination, inability to name objects |
|
|
|
Occipital lobe |
Primary visual area in back of brain Sub cortical regions: thalamus & hypothalamus |
|
|
|
Thalamus |
All sensory info passes through here and gets sensors before heading to the primary region of the occipital lobe (except olfaction) |
|
|
|
Hypothalamus |
Controls body temperature & hormone release (adrenaline & sex hormones) |
|
|
|
Reticular formation |
Responsible for attention, alertness, & some reflexes Damage: coma |
|
|
|
Spinal cord |
Reflex arc: we have no control over these reflexes Communication btw/ body and brain PRIMITIVE |
|
|
|
Central Nervous System |
Brain and spinal cord |
|
|
|
Peripheral Nervous System |
Intricate network of nerves carries info to and from the CNS |
|
|
|
Somatic Nervous System |
Carries messages to and from the brain/body Active during voluntary behavior |
|
|
|
Autonomic Nervous System |
Self governing system that controls organs and glands we don't have control over |
|
|
|
Sympathetic Nervous System |
Danger response Inhibits tears, activated sweat glands, adrenaline |
|
|
|
Parasympathetic Nervous System |
Chill response Constricts pupils, stimulates salivation, calms you down |
|
|
|
Glial cells |
Scaffolding -nourishment, repair, and support |
|
|
|
Dendrite |
Cluster of fibers at one end of a neuron that receives messages |
|
|
|
Axon |
Carries messages destined for other neurons |
|
|
|
Terminal buttons |
Small bulges at the end of the axon that send messages |
|
|
|
Myelin sheath |
Protective coat of fat and protein that surrounds the axons Damage: MS |
|
|
|
Gray matter |
Contains numerous cell bodies and less myelinated axons What we see |
|
|
|
White matter |
Highly myelinated axons UNDER gray matter. -like super highway |
|
|
|
Resting state |
Negative charge of about -70 millivolts within a nueron |
|
|
|
Action potential |
Nerve impulses travel through an axon after they are set off by a positive trigger |
|
|
|
Synapse |
Space between neurons |
|
|
|
Excitatory NT |
"Fire!" Ex- Acetylchlorine |
|
|
|
Inhibitory NT |
"Don't fire!" Ex- GABA |
|
|
|
Psychoactive drugs |
A drug capable of altering attention, emotion, judgement, memory, time sense, self control, or perception |
|
|
|
Blood Brain Barrier |
A semi permeable wall that protects the brain from "foreign substances" in he blood that may damage the brain, protects the brain from hormones and NT in the rest of the body, and maintains a consistent environment for the brain |
|
|
|
Agonistic |
Increase the release of NT (ecstasy), bonds to post synaptic receptors and activates/increases their effects, blocks the deactivation of NTs by blocking degradation of reuptake |
|
|
|
Antagonistic |
Activates autoreceptors, inhibits NT release, binds to the post synaptic receptors and blocks the effect of the NT |
|
|
|
Downers |
Barbiturates Xanax |
|
|
|
Uppers |
Nicotine Ecstasy |
|
|
|
Psychotropic drugs |
A chemical substance that changes brain function and results in alterations in perception, mood, or consciousness. |
|
|
|
Off label drug use |
Prescribing/taking medication for something other than its intended purpose |
|
|
|
SSRI |
Selective Serotonin Re-uptake Inhibitors Ex- Prozac and lexapro |
|
|
|
Antipsychotics |
Primarily used in aiding the functions of psychosis Work primarily for positive (addition of) symptoms Reduce dopamine 1. Dopamine 2. Serotonin 3. Both partials |
|
|
|
Sensation |
The detection of physical energy emitted or reflected by physical objects -sense organ receptors are stimulated |
|
|
|
Perception |
The process by which the brain organizes and interprets sensory information. |
|
|
|
Stimuli |
Energy that produces a response in a sense organ |
|
