Test 3 Flashcards
Anterior cingulate cortex
Collar around corpus collision
Making errors may cause changes in dopamine
Basal ganglia
Responsible for implicit learning
Cerebellum
Attention, language and motor control, coordination-timing-precision, clap
Cochlea
Hexagonal clusters of cilia
Corpus collosum
Wide, flat bundle of neural fibers under the cortex
Small is dyslexic children
Dorsolateral area
Sleep deprivation inhibits activity in this area
Frontal lobe
Easily injured, 3 regions
Hippocampus
Consolidation
STM into LTM
Hypothalamus
Regulates body temp, hunger, thirst, sleep, and controls pituitary gland
LGN
Vision pre-processing
Medulla oblongata
Centers that control respiration, vomiting, heart rate and blood pressure
MGN
Sound pre-processing
Occipital lobe
Primary projection area for vision
Optic chiasm
Cross your nose
Orbitofrontal area
Drug cravings
Parietal lobe
3-D view of the world, pain, touch, math processing (left for additions and subtraction, right for quantity processing)
Pineal gland
Melatonin (more as in dark)
Pons
Relay between thalamus, medulla and cerebellum; sleep paralysis, dreaming, taste-chewing-saliva and swallowing
Prefrontal cortex
Contains dorsolateral, orbitofrontal and ventromedial areas
Primary motor cortex
Voluntary movements, homunculus
Reticular formation
Irreversible coma
Retina
Rods, cones, horizontal, amacrine, bipolar
Secondary motor cortex
Coordinates complex 2-hand movements
Superior temporal lobe
Primary projection area for sound
Concentrically organized
Temporal lobe
Language, vision, mathematics, and sound
Thalamus
Switchboard
Regulates consciousness and sleep
Many nuclei (LGN, MGN, hypothalamus)
Ventralmedial
Social function and emotional regulation
Smooth muscle
Liver, stomach, organs
Striated muscle
Arm, leg

Executive process
Ability to switch from task to task
Females
Cyclic hormone release
Look at folks more than trucks by 6 months
Habituation
Ignoring repetitive stimuli
Consciousness
All or nothing
Gender
How you identify sexually (I am a girl)
Gender role
Bake or play baseball
Müllerian ducts
Female internals
Wolffian ducts
Male internals
ADHD
Predominantly inattentive

Depression
Pulling away from friends Trouble concentrating Trouble sleeping Feeling helpless Suicidal
Mania
Elevated irritability Extreme energy Racing thoughts Overconfidence Frenzy Risky behavior Suicidal
Mixed episode
Mania and depressed at the same time
Seasonal affective disorder
Effects of annual cycle and sunlight
Obesity
Buffet of high calorie foods, lose interest in other rewards, eat some of all the foods, can’t pass up any option, become obese
Fructose and glucose have different gastric emptying rates, impacts on hunger, endocrine profiles, metabolic rates
Panic disorder
Influenced by genetics
More common in women and teens
Don’t give glutamate
Parkinson’s disease
Tremors, substantial nigra, more men than women
PTSD
Angry outbursts
Hyperarousal
Avoidance
Williams syndrome

Schizophrenia - negative symptoms
Emotional response, lack of pleasure
Schizophrenia : Positive symptoms
Hallucinations
Delusions
Thought disorders
Schizophrenia
Episodes typically start during teens, vary in intensity
Flu is a contributing factor
More likely if born in later winter, live far from the equator, low birth weight, different Rh factor, mother underweight
Hallucinations can be any sense, but usually hearing (voices)
