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. Emotional perception and expression (particularly fearful emotions and detection of threat)






2. Can occur after long term antipsychotic tx (opposite of Parkinson'S?); oversensitivity to dopamine






3. Smooth electrical activity of 8-12 Hz -medium frequency - awake but in a restful state (^ eyes closed but conscious)






4. Similarity of alleles for a trait in an organism (i.e. heterozygous or homozygous)






5. Includes the tectum and tegmentum






6. Occurs when their is damage to the septal area and results in unchecked aggressive and vicious behavior






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






8. Abducens Nerve - moves eye






9. Important to motor system






10. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






11. Binding of a drug to a receptor site that does not interfere with the binding site for the principal ligand






12. Is increased in its production by training/experience and therefore - associated with memory






13. The scientific study of animal behavior; documentation of species-specific instinctual behaviors






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






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






16. 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






17. The Lee-Boot effect - Whitten effect - Vandenbergh effect - and the Bruce effect; all mediated by the VNO






18. 'Roof'






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






20. Is a peptide neurotransmitter and a natural painkiller and antianxiety






21. Functions as both a hormone and a neurotransmitter in the brain






22. Comprised of the hypothalamus - pituitary gland - thyroid gland - parathyroid - the adrenal cortex - the adrenal medulla - the pancreas - the ovaries/testes - pineal gland.






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






24. Is a loss of dopamine cells in the substantia nigra of the basal ganglia; these cells are usually dark (nigra) but in Parkinson'S - the substantia nigra appears white due to cell death

25. Most brain communications are with the opposite side of the body






26. Hormone secreted during the night by the pineal body; role in circadian and seasonal rhythms






27. Receptors whose activation directly affects potassium or chloride ion channels in the neuron - (many drugs of abuse substitute for natural GABA- alcohol - benzos - barbituates






28. Occur in amacrine - bipolar and horizontal cells; govern/encompass the opponent-process level of color vision






29. Part of a glial cell that wraps around the axon of a neuron - providing insulation that facilitates speed of propagation of action potential






30. Associated with (spoken) language reception/comprehension - memory processing - and emotional control; contains Wernicke'S area and the auditory cortex






31. Midbrain - medulla and the pons






32. Affect multiple receptors; highly preferential to which type of receptor they affect






33. These two developed the criteria for habituation; basic process is a form of synaptic depression that occurs presyntaptically.






34. These two brain structures contain entry/exits for most of the cranial nerves and control vital functions (heart rate -digestion - respiration)






35. Caudate nucleus and putamen






36. Is characteristic of indirect antagonists






37. Holds the lens in place






38. Glossopharyngeal Nerve - taste swallow






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






40. 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






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






42. Areas in the brain receiving incoming sensory information or sending out motor-impulse commands






43. Instead of one continuum for sex (masculine-feminine) - her work in the presence of both masculine and feminine features/development suggests these are actually two separate continuums (defeminized-feminized and unmasculinized-masculinized)

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






45. Affect sex characteristics/development and produce estrogen/progesterone (in females - ovaries) and testosterone (in male - testes)






46. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






47. Opening in the iris; dilates and contracts allowing different levels of light in






48. Viscous substance between cornea and lens; transparent substance between lens and retina






49. Sleepwalking - sleep talking






50. Ventral part of midbrain - includes periaqueductal gray matter - reticular formation - red nucleus - and substantia nigra
