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. Glossopharyngeal Nerve - taste swallow






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






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






4. Includes the tectum and tegmentum






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






6. The female reproductive cycle of mammals other than primates






7. 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






8. 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)






9. Damage to this are causes clumsiness and loss of balance






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






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






12. Occurs under drug-induced conditions - including excessive use of marijuana; high body temperature - autonomic instability and muscle rigidity






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






14. 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

15. Cells that integrate information across the retina; rather than sending signals toward the brain - amacrine cells link bipolar cells to other bipolar cells and ganglion cells to other ganglion cells






16. Controls sexual activity; lesions inhibit sexual behavior; stimulation increases aggressive sexual behavior






17. Somewhat excitatory - also involved in synaptic plasticity - learning and short-term memory






18. 'little net'






19. Governs eating/drinking (lateral and ventromedial hypothalami) and sexual activity (anterior portion






20. Found in the ventricles and spinal canal






21. Neurotransmitter in CNS - hormone in peripheral vascular system; deficiencies > depression - ADD; noradrenergic nuclei = locus coeruleus






22. 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






23. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






24. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






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






26. Are found in the diencephalon






27. Self-dissolving






28. Vision: protrusions on top of the midbrain; part of visual system






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






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






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






32. Facial Nerve - moves face and salivates






33. Projects to ventral tegmental area






34. Has neurons for reflexes






35. In the limbic system - is a fiber bundle - connects hippocampus with stuff (including the mammillary bodies of the hypothalamus)






36. Is characteristic of indirect antagonists






37. 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)






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






39. Is everything anterior to the central sulcus






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






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






42. A patient who had intact intelligence but an inability to learn/remember anything new (severe anterograde amnesia)






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






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






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






46. Dorsal part of midbrain; includes the superior and inferior colliculi






47. Regulates body temperature






48. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






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






50. Smooth electrical activity of 8-12 Hz -medium frequency - awake but in a restful state (^ eyes closed but conscious)
