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. A chemical released by one animal that affects the behavior or physiology of another animal; usually smelled or tasted






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






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






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






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






6. 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)






7. Abducens Nerve - moves eye






8. Is characteristic of indirect antagonists






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






10. 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

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






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






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






14. Vagus Nerve - heart rate and digestion






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






16. Motor neurons found in the Somatic (voluntary) and Autonomic (involuntary) Nervous Systems






17. Referred to as the satiety center; lesions lead to obesity and hyperphagia






18. 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






19. Trigerminal Nerve - face sensation






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






21. Skin senses that register the sensations of pressure - warmth and cold






22. Is regulated by the hypothalamus






23. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






24. Made from within - natural






25. 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






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






27. Self-dissolving






28. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






29. 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






30. Research indicates that the expressing of negative emotions is associated with increased immune function; inhibiting negative emotions with decreasing immune function






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






32. 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






33. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






34. Decreasing effects of a medication due to repeated administration






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






36. 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)






37. A BEHAVIOR; insistent urge of sleepiness forces us to seek sleep/a bad






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






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






40. Part of a glial cell that wraps around the axon of a neuron - providing insulation that facilitates speed of propagation of action potential






41. Focuses light waves on the retina and is held in place by the suspensory ligament; aqueous humor on cornea side; vitreous humor on retina side






42. Most brain communications are with the opposite side of the body






43. Lens changes initiated by the ciliary muscles to change the shape of the lens in order to focus image on the retina






44. 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






45. Regulates body temperature






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






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






48. Holds the lens in place






49. Controls sexual activity






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