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. Facial Nerve - moves face and salivates






2. Measure changes in the electrical resistance of the skin (sweat gland activity)






3. 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






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






5. Is regulated by the hypothalamus






6. An area that combines input from diverse brain regions






7. Is used as an anaesthetic for children and animals but causes psychosis in adults






8. Is an oversensitivity to dopamine (D2)






9. Activates one of 5 types of receptors in the CNS - cognition - motor activity - reward - muscle tone - sleep - mood - attention - learning -higher level effects of dopamine = D2






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






11. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






12. Hypoglossal Nerve - moves the tongue






13. Attaches to the binding site on a receptor and interferes with the receptor'S action - but NOT by interfering with the principal ligand'S binding site (noncompetitive binding)






14. If head is rotated - eye movements occur in the same direction






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






16. Is the primary inhibitory neurotransmitter in vertebrates; these receptors are ionotropic






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






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






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






20. Has a calcium-related role and produces the hormone parathyroid






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






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






23. 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






24. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






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






26. Cornea - aqueous humor - pupil - lens - vitreous humor - retina






27. Made from within - natural






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






29. The restorative effect of introducing a new female sex partner to a male that has apparently become 'exhausted' by sexual activity






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






31. Trigerminal Nerve - face sensation






32. Produce drowsiness and sleepiness






33. Is found between the dura mater and arachnoid mater meninges






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






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






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






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






38. Is everything anterior to the central sulcus






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






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






41. Transparent substance between lens and retina






42. Oculomotor Nerve - moves eye pupil






43. Is found between the arachnoid mater and Pia mater; this is where CSF cushions (and bathes) the brain - giving it the floating quality (and keeping it moist/circulating)






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






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






46. Tremors - rigidity of limbs - poor balance and difficulty initiating movements

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






48. The visual image of the world on the retina






49. 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

50. The female reproductive cycle of most primates - including humans; recognized by growth of the lining of the uterus - ovulation - development of a corpus luteum - and (if pregnancy does not occur) menstration
