Chapters 3 and 5 (Gerrig and Zimbardo, 18th Edition)
Question | Answer |
---|---|
Bipedalism and Ecephalization are responsible for what? | Language Development |
EEG | electroencephalogram, studies relationship between psychological activites and brain response |
PET | Positron Emission Tomography, given different kinds of radioactive substances which help to record different cognitive or behavioral activites |
MRI | Magnetic Resonance Imaging, can generate imageds of the locations of different atoms in areas of the brain |
neurotransmitters | biological substances that stimulate other neurons |
Acetylcholine | Alzheimers disease, deterioration of the ability to secrete acyetylcholine; causes muscles to contract; affected by botulism; Amazon Indians made a poison out of botulinum that occupies acetylcholine receptors |
GABA | particularly sensitive:Thalamus, Hypothalamus, Occipital Lobes; low levels = anxiety |
Dopamine | high levels found in people with schizophrenia, Parkinson's is from deterioration of the ability to produce dopamine |
Seratonin | neruons that produce are located in the brain stem; involved in arousal and many autonomic processes; LSD suppresses Seratonin |
Norepinephrine | involved in some forms of depression |
Central Nervous System | Brain and Spinal Cord |
Peripheral Nervous System | nerve fibers that connect the CNS to the rest of the body |
What are the two major components of the Peripheral Nervous System | Somative Nervous System and the Autonomic Nervous System |
Brain Stem | primarily involved with autonomic provesses such as heart rate, breathing, swallowing and digestion |
Limbic System | involved with motivation, emotion, memory processes |
Medulla | located at the top of the spinal cord, center for breathing, blood pressure, and the beating of the heart |
Pons | provides inputs to other structures (Latin for Bridge) |
Reticular Formation | dense network of nerve cells that serves as the brain's sentinel, keeps the brain alert even during sleep |
Thalamus | channels incoming sensory information to the appropriate area of the cerebral Cortex |
Limbic System's 3 parts: | Hippocampus, Amygdala, Hypothalamus |
Cerebellum | attached to the brain stem at the base of the skull, coordinates bodily movements, controls posture, and maintains balance (equilibrium) |
Hippocampus | largest of the limbic system structures; important in the acquisition of memories |
Amygdala | plays a role in emotion control and formation of emotional memories |
Hypothalamus | one of the smallest structures in the brain, maintaints the body's internal equilibrium (homeostasis); regulates temperature, regulates hunger and eating; regulates the activities of the endocrine system |
Cerebrum and Corpus Colosum | Cerebrum regulates the brain's higher cognitive and emotional functions, corpus collosum connects the 2 hemispheres through a thick mass of nerve fibers |
Left brain is responsible for ______ | Language |
Pituitary Gland | master gland, produces about 10 kinds of hormones including one for growth, as well as testosterone for males and estrogen for females |
Thyroid Gland | metabolism, growth and development |
Adrenal Glands | fight or flight responses, metabolism, sexual desire in women |
Pancreas Glands | glucose metabolism |
Hallucinogens | LSD, PCP, Cannabis |
Opiates (Narcotics) | Morphine, Heroin |
Depressants | Barbituates, Benzodiazepines, Rohypnol, GHB, Alcohol |
Stimulants | Amphetamines, Methamphetamines, MDMA (Ecstasy), Cocain, Nicotine, Caffeine |
