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. learning and memory -neurotransmitter released at the neuromuscular junction of skeletal muscle axons to excite the muscle to contract






2. 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






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






4. Binding of drug to receptor site that doesn'T interfere with the principal ligand






5. 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)

6. Sign






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






8. Cumulative effects of repeated stimulation from a presynaptic neuron






9. Dorsal part of midbrain; includes the superior and inferior colliculi






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






11. Sleepwalking - sleep talking






12. 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

13. 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






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






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






16. Consummatory stimulus






17. A steroid hormone produced by the ovary that maintains the endometrial lining of the uterus during the later part of the menstrual cycle and during pregnancy; along with estradiol it promotes receptivity in female mammals with estrous cycles






18. Vestibulocochlear Nerve - hearing and balance






19. Important to motor system






20. Is an oversensitivity to dopamine (D2)






21. SCN = controls circadian rhythms - located directly above the optic chasm in the anterior portion of the hypothalamus - receives input from the eyes which is why light exposure affects our sleep-wake cycles






22. Regulates body temperature






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






24. Refers to both the somatosensory cortex and motor cortex (they are a little different but very interrelated)






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






26. Found in the hypothalamus - function to maintain the water balance in the body






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






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






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






30. The viscous substance between cornea and lens






31. 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






32. Is found at the base of the brain - underneath the thalamus (**remember hypo-below)






33. Functions in metabolism (carbohydrate - protein - lipid) and in the endocrine system'S salt/water balance - produces the hormones cortisol and aldosterone






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






35. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






36. Has a major role in metabolism - stimulation/maintenance - produces the hormones thyroxin and calcitonin






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






38. The synchronization of the menstrual or estrous cycles of a group of females - which occurs only in the presence of a pheromone in a male'S urine






39. Trigerminal Nerve - face sensation






40. Produce drowsiness and sleepiness






41. Cells that integrate information across the retina; rather than sending signals toward the brain - amacrine cells link bipolar cells to other bipolar cells and ganglion cells to other ganglion cells






42. Bunch of dopaminergic neurons starting in the substantia nigra and ending in the neostriatum






43. There are 12 add more






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






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






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






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. Accessory Nerve - moves the head






49. A patient who had intact intelligence but an inability to learn/remember anything new (severe anterograde amnesia)






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