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. First described by Descartes - a combination of antagonistic muscle movements (e.g. those involved in walking)






2. 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)

3. A region of the visual association cortex located in the extrastriate cortex at the base of the brain that has special face-recognizing circuits (more important in right hemisphere)






4. Sudden - sharp waveforms found only in Stage II of sleep; spontaneously occur about one per minute but also to unexpected noises






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






6. Are direct antagonists; binds with a receptor but does not activate it - but prevents the natural ligand from binding with the receptor






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






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






9. Short bursts of waves 12-14 Hz that occur 2-5 times a minute during stages 1-4 of sleep; most characteristic of sleep Stage II; some believe sleep spindles are involved in keeping one asleep (decline in older people)






10. 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






11. Related to plasticity - the term Lashley used to describe different parts of the cortex being interchangeable in their roles in learning






12. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






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






14. Is everything anterior to the central sulcus






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






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






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






18. An axon of a neuron in one region of the brain whose terminals form synapses with neurons in another region






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






20. 'little brain'






21. Produces acetylcholine. One of the earliest sites of cell death in Alzheimer'S Disease (neurological disorder associated with a deficiency in acetylcholine) is in the basal forebrain






22. Sign






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






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






25. Produce drowsiness and sleepiness






26. Located in the midbrain - a group of neurons which produce dopamine and degenerate in Parkinson'S Disease






27. Controls sexual activity






28. Projects to ventral tegmental area






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






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






31. Occurs at the onset of puberty; a hypothalamic hormone that stimulates the pituitary gland to secrete gonadotropin






32. Made from within - natural






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






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






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






36. Is characteristic of indirect antagonist drugs






37. Vestibulocochlear Nerve - hearing and balance






38. 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






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






40. Moving forward






41. 'Roof'






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






43. Maintains balance/posture and coordinates body movements






44. Choroid Plexus > Ventricle 1 & 2 > Foramen of Monro > Ventricle 3 > Aqueduct of Sylvius > Ventricle 4 > Foramen of Magendie lateral aperture) > Foramina of Luschka (lateral aperture) - subarachnoid space (outside of brain) and spinal cord > re-absorp






45. 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






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






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






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






49. Is characteristic of indirect antagonists






50. 'covering'
