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. 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






2. A sensory organ that detects the presence of certain chemicals - especially when a liquid is actively sniffed; mediates the effects of some pheromones






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






4. 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






5. Caudate nucleus and putamen






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






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






8. ...






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






10. Controls sexual activity






11. Trigerminal Nerve - face sensation






12. Some brain communications are with the same side of the body






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






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






15. Symptom of narcolepsy - irresistible urge to






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






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






18. Pass the easiest through the blood-brain barrier






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






20. 1. ventral tegmentum to mesolimbic forebrain (cognition - reward systems - emotional behavior) 2. substantia nigra to caudate nucleus putamen (movement and sensory stimulation) 3. hypothalamus to pituitary gland (neuronal/hormonal control)






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






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






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






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






25. Affect sex characteristics/development and produce estrogen/progesterone (in females - ovaries) and testosterone (in male - testes)






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






27. 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)






28. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






29. Also known as ABLATION - is any surgically induced brain lesion






30. 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)






31. 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)






32. Most pervasive excitatory neurotransmitter in the brain






33. Sleepwalking - sleep talking






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






35. 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






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






37. Is characteristic of indirect antagonists






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






39. Moving forward






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






41. Glossopharyngeal Nerve - taste swallow






42. Binding of a drug to a receptor site that does not interfere with the binding site for the principal ligand






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






44. The maintenance of water balance in the body






45. Projects to ventral tegmental area






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






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






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






49. Include tolerance (possible withdrawal) and sensitivity






50. Norepinephrine and serotonin
