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
