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






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






3. Pass the easiest through the blood-brain barrier






4. hormone - secreted by the pituitary gland -signals the adrenal gland to secrete corticosteroid hormones -ACTH is a critical component of the HPA Axis that controls the stress response






5. Hypothalamic-pituitary-adrenal axis -controls stress response






6. These two brain structures contain entry/exits for most of the cranial nerves and control vital functions (heart rate -digestion - respiration)






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






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






9. Made from within - natural






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






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






12. Auditory receptor cells in the cochlea that turn sound vibrations -> neural impulses






13. Readiness with which molecules/drugs/medications join together; varies widely from medication to medication






14. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell






15. Maintains balance/posture and coordinates body movements






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






17. Relays nerve impulses - processes sensory impulses - reflex behavior and contains nerve cell bodies






18. Two different presynaptic neurons/inputs to a post-synaptic cell






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






20. 'little net'






21. 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)






22. Vagus Nerve - heart rate and digestion






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






24. Sign






25. Found in the hypothalamus - function to maintain the water balance in the body






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






27. There are 12 add more






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






29. 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






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






31. A single - unfertilized cell created during conception; the combined egg + sperm






32. Facial Nerve - moves face and salivates






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






34. The female reproductive cycle of mammals other than primates






35. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






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






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






38. Important to motor system






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






40. 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






41. Cumulative effects of repeated stimulation from a presynaptic neuron






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






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






44. Trochlear Nerve - moves eye






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






46. Short bursts of waves 12-14 Hz that occur 2-5 times a minute during stages 1-4 of sleep; most characteristic of sleep Stage II; some believe sleep spindles are involved in keeping one asleep (decline in older people)






47. Sudden - sharp waveforms found only in Stage II of sleep; spontaneously occur about one per minute but also to unexpected noises






48. Glossopharyngeal Nerve - taste swallow






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






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