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






2. 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






3. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






4. Expression of traits






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






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






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






8. Occurs for body temperature - blood glucose levels - blood concentration - etc -hormones are important






9. Has two lobes that are connected by the massa intermedia (looks like a pair of balls - without the nutsack)






10. Most pervasive excitatory neurotransmitter in the brain






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






12. Decreases with age up until age 30 - then begins to increase *(counter intuitive)*






13. Neurotransmitter in CNS - hormone in peripheral vascular system; deficiencies > depression - ADD; noradrenergic nuclei = locus coeruleus






14. 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






15. Consummatory stimulus






16. Found that developmental changes occurring in puberty make the brain more susceptible to the psychotic effects of NDMA antagonist and therefore also related to the emergence of symptoms of schizophrenia






17. Portion of a sensory field to which a cell responds






18. Includes the thalamus and hypothalamus; region of forebrain surrounding the 3rd ventricle






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






20. An anterograde amnesia in which one cannot form episodic memories BUT in experiments - patients that cannot identify previously heard melodies do show a preference for them -> explicit memory function has a different neurological basis than implicit

21. Trigerminal Nerve - face sensation






22. Abducens Nerve - moves eye






23. Controls sexual activity






24. 'little net'






25. A behavior that has different forms or occurs with different probabilities or under different circumstances in males than females






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






27. Moving forward






28. Readiness with which molecules/drugs/medications join together; varies widely from medication to medication






29. Sleep tests (i.e. to diagnosis sleep apnea)






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






31. EEG desynchrony (rapid -irregular waves) - lack of muscle tonus - rapid eye movements - penile erection/vaginal secretion - dreams; EEG synchrony (slow waves) - moderate muscle tonus - slow/absent eye movements - lack of genital activity






32. Automatic and rapidly acquired reactions - not attributable to reinforcement or conditioning






33. 'covering'






34. Is regulated by the hypothalamus






35. Projects to ventral tegmental area






36. Facial Nerve - moves face and salivates






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






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






39. Stimulates bone growth and produces the hormones: somatotropin - prolactin - thyroid-stimulating - adrenocorticotropic (ACTH) - follicle-stimulating - luteinnizing






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






41. Precursor to GABA (the most inhibitory/regulatory/pervasive neurotransmitter)






42. The midbrain; a region that surrounds the cerebral aqueduct; includes tectum and the tegmentum






43. A drug that opposes/inhibits the effects of a particular neurotransmitter on the postsynaptic cell






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






45. Is used to treat Parkinson'S Disease






46. Is found in PTSD/CPTSD patients and persons exposed to chronic stress






47. Sits just above the hindbrain - contains cranial nerves - parts of the reticular formation -important relay stations for sensory information and the substantia nigra






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






49. The slowing and eventual cessation of estrous cycles in groups of female animals that are housed together; caused by a pheromone in the animals urine and first observed in mice






50. Having two copies of each chromosomes in most cells (except the gametes) - e.g. most mammals
