Gre Psychology: Experimental/natural Science Biology

Subjects : gre, psychology
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Receptors whose activation directly affects potassium or chloride ion channels in the neuron - (many drugs of abuse substitute for natural GABA- alcohol - benzos - barbituates






2. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






3. A peptide - also known as OREXIN - produced by neurons whose cell bodies are located in the hypothalamus; their destruction causes narcolepsy






4. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell






5. Pleasure center of the brain; discovered by Olds & Milner






6. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in prefrontal cortex






7. Occurs under drug-induced conditions - including excessive use of marijuana; high body temperature - autonomic instability and muscle rigidity






8. Thymoleptics = relieves mania of bipolar disorder (lithium carbonate - valproic acid - carbamazepine)






9. Pass the easiest through the blood-brain barrier






10. Expression of traits






11. Acetylcholine - glutamate - gamma-aminobutyric acid - dopamine - serotonin - norepinephrine - endorphin






12. Associated with defensive and aggressive behavior; lesions produce docility and hypersexual states (Kluver & Bucy)






13. Somewhat excitatory - also involved in synaptic plasticity - learning and short-term memory






14. Increasing effects/effectiveness of a medication due to repeated administration






15. Is found between the arachnoid mater and Pia mater; this is where CSF cushions (and bathes) the brain - giving it the floating quality (and keeping it moist/circulating)






16. One of the primary noradrenergic nuclei whose ascending axons project to frontal cortex - thalamus - hypothalamus - limbic system






17. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






18. Increases heartrate - dilates/constricts blood vessels - increases blood sugar - produces hormones epinephrine and norepinephrine






19. 'covering'






20. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






21. The increase in REM sleep seen after a period of REM sleep deprivation






22. In the posterior frontal lobe - contains the somatosensory cortex (touch - pressure - temperature - pain)






23. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






24. Junction of the sagittal and coronal sutures of the skull; often used as a reference point for stereotaxic brain surgery






25. Begins where spinal cord ends - 3 structures: the medulla - the pons - the cerebellum






26. Holds the lens in place






27. Means 'Savory' in Japanese and is a taste receptor found on the tongue; activated by glutamate present in meats - cheese and other protein heavy foods






28. Some brain communications are with the same side of the body






29. Part of limbic system; protrusion of the bottom of the brain at the posterior end of the hypothalamus - contains some hypothalamic nuclei






30. Trigerminal Nerve - face sensation






31. Involved in the effects of odors/pheromones in reproductive behavior - a nucleus that receives olfactory information from the olfactory bulb and accessory olfactory bulb






32. Receive incoming sensory information or send out motor impulse commands






33. Occurs intermittently during early stages of slow-wave sleep and REM sleep 3.5-7.5 Hz






34. Glandular system control center - produces the hormones oxytocin and antidiuretic; functions in both the nervous system and endocrine sytem - In the forebrain - regulates motivated behaviors (eating - drinking - aggression - sexual behavior






35. Occurs during the deepest stages of slow-wave sleep; regular - synchronous electrical activity of less than 4 Hz






36. Hypothalamic-pituitary-adrenal axis -controls stress response






37. Has neurons for reflexes






38. Two different presynaptic neurons/inputs to a post-synaptic cell






39. Optic Nerve - sight






40. Midbrain - medulla and the pons






41. A BEHAVIOR; insistent urge of sleepiness forces us to seek sleep/a bad






42. Sign






43. Is used to treat Parkinson'S Disease






44. Is a receptor blocker; binds with a receptor but does not activate it - actually prevents the natural ligand from binding with the receptor






45. A large network of neural tissue located in the central region of the brain stem - from the medulla to the diencephalon






46. Has a calcium-related role and produces the hormone parathyroid






47. Include the Nigrostriatal system - Mesolimbic system and Mesocortical system






48. Reduces anxiety - released with NE in amygdala - hippocampus - basal ganglia - periaqueductal gray region - locus coeruleus and PFS; NPY is diminished in persons with PTSD/CPTSD and those exposed to chronic stress






49. Glossopharyngeal Nerve - taste swallow






50. Is found in the frontal lobe (which is divided into the prefrontal lobes and ___ ___)
