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. Is a peptide neurotransmitter and a natural painkiller and antianxiety






2. Trigerminal Nerve - face sensation






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






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






5. 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






6. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






7. Audition: protrusions on top of midbrain; part of auditory system






8. Is regulated by the hypothalamus






9. Occurs intermittently during early stages of slow-wave sleep and REM sleep 3.5-7.5 Hz






10. 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)






11. 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






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






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






14. Hormones that reduce pain






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






16. Abducens Nerve - moves eye






17. 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)






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






19. Receptors whose activation directly affects potassium or chloride ion channels in the neuron - (many drugs of abuse substitute for natural GABA- alcohol - benzos - barbituates






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






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






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






23. 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)






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






25. Emotional perception and expression (particularly fearful emotions and detection of threat)






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






27. 'little net'






28. Is found in the frontal lobe (which is divided into the prefrontal lobes and ___ ___)






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






30. Produce drowsiness and sleepiness






31. Moving forward






32. Expression of traits






33. Acetylcholine - glutamate - gamma-aminobutyric acid - dopamine - serotonin - norepinephrine - endorphin






34. 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






35. 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

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






37. Is increased in its production by training/experience and therefore - associated with memory






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






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






40. A large network of neural tissue located in the central region of the brain stem - from the medulla to the diencephalon






41. Convoluted of hills (gyri) and valleys (sulci) divided into two hemispheres (left and right) which are further divided into four lobes (occipital - parietal - temporal and frontal)






42. Is a receptor blocker; binds with a receptor but does not activate it - actually prevents the natural ligand from binding with the receptor






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






44. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






45. Norepinephrine and serotonin






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






47. Adenine - Guanine - Thymine - Cytosine






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






49. A steroid hormone produced by the ovary that maintains the endometrial lining of the uterus during the later part of the menstrual cycle and during pregnancy; along with estradiol it promotes receptivity in female mammals with estrous cycles






50. Hypoglossal Nerve - moves the tongue
