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






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






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






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






5. 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)






6. AKA the striate cortex - located at the back of the brain - and contains the visual cortex






7. Comprised of the hypothalamus - pituitary gland - thyroid gland - parathyroid - the adrenal cortex - the adrenal medulla - the pancreas - the ovaries/testes - pineal gland.






8. These cells perform a variety of functions but do not transmit information; one type forms the myelin sheath






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

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






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






12. 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






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






14. Portion of a sensory field to which a cell responds






15. Hypoglossal Nerve - moves the tongue






16. Facial Nerve - moves face and salivates






17. 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






18. Precursor to GABA (the most inhibitory/regulatory/pervasive neurotransmitter)






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






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






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






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






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






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






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






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






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






28. Is characteristic of indirect antagonists






29. Is found in the interior rostral temporal lobe - part of limbic system






30. Sits just above the hindbrain - contains cranial nerves - parts of the reticular formation -important relay stations for sensory information and the substantia nigra






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






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






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






34. The Lee-Boot effect - Whitten effect - Vandenbergh effect - and the Bruce effect; all mediated by the VNO






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






36. Include tolerance (possible withdrawal) and sensitivity






37. Olfactory Nerve - smell






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. A 90-minute activity cycle occurs throughout the day as well as throughout sleep (in humans) waxing and waning alertness controlled by a biological clock in the caudal brainstem that also controls cycles of REM and slow-wave sleep






40. Expression of traits






41. Precursor to the catecholamine neurotransmitters (DA + NE)






42. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






43. 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)






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






45. Thymoleptics = relieves mania of bipolar disorder (lithium carbonate - valproic acid - carbamazepine)






46. 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






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






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






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






50. 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
