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 drug to receptor site that doesn'T interfere with the principal ligand






2. Include indolamines (serotonin) and catecholamines (dopamine - norepinephrine and epinephrine)






3. Acquired language disorders - usually caused by damage in the left hemisphere; includes Broca'S: (left frontal lobe damage) and Wernickes'S (left temporal/parietal damage)






4. Supernormal






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






6. Accessory Nerve - moves the head






7. Self-dissolving






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






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






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






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






12. 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






13. Is characteristic of indirect antagonist drugs






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






15. If a synapse is active at about the same time that a postsynaptic neuron is active - that synapse will be strengthened






16. Projects to ventral tegmental area






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






18. Serotonin = 5-HT -regulation of mood - anxiety - aggression - sleep - appetite - sexuality -rostral and caudal raphe nuclei






19. Lesions to this brain structure that is crucial to memory will produce anterograde amnesia






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






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






22. An ovary or teste






23. Mechanism whereby neurons make connections to new areas to change their connectivity






24. Completely disactivates the prefrontal cortex (PFC); due to high levels of norepinephrine (NE)






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






26. Occurs when an external stimulation - regardless of intensity - will not trigger a new action potential






27. Important to motor system






28. Symptom of narcolepsy; complete paralysis that occurs while AWAKE/conscious; will suddenly fall to floor paralyzed for a few minutes






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






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






31. Auditory receptor cells in the cochlea that turn sound vibrations -> neural impulses






32. The maintenance of water balance in the body






33. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






34. Links the nervous system and endocrine system; comprised of involuntary efferent neurons and divided into the Sympathetic and Parasympathetic branches: Sympathetic Nervous System is involved in the 'fight or flight' response and the Parasympathetic N






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






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






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






38. Forebrain -band of nerve fibers connecting the two cerebral hemispheres






39. Vision: protrusions on top of the midbrain; part of visual system






40. Result in either tolerance (and possible withdrawal symptoms) or sensitization (increase effectiveness of the drug)






41. The viscous substance between cornea and lens






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






43. All have similar molecular structure - so many 'dirty' medications






44. States that performance is worst at extremely low or extremely high levels of arousal and optimally at an intermediate level






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






46. The female reproductive cycle of mammals other than primates






47. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)






48. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






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






50. hormone - secreted by the pituitary gland -signals the adrenal gland to secrete corticosteroid hormones -ACTH is a critical component of the HPA Axis that controls the stress response
