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 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

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






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






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






5. Bunch of dopaminergic neurons starting in the substantia nigra and ending in the neostriatum






6. A behavior that has different forms or occurs with different probabilities or under different circumstances in males than females






7. 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)






8. Physiologically different from the other four stages of sleep (i.e. the similarity between the summed electrical activity of neurons measured on the scalp (EEG) during REM sleep and during wakefulness






9. Is characteristic of indirect antagonist drugs






10. 1. Stage I (non-REM sleep) 2. Stage II (non-REM sleep 3. Stage III (non-REM sleep - slow-wave sleep) 4. Stage IV (non-REM sleep - slow-wave sleep) 5. Rapid Eye Movement Sleep (REM sleep) ~takes about 90 minutes for one full sleep cycle






11. Referred to as the satiety center; lesions lead to obesity and hyperphagia






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






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






14. Mechanism whereby neurons make connections to new areas to change their connectivity






15. Reduces anxiety - released with NE in amygdala - hippocampus - basal ganglia - periaqueductal gray region - locus coeruleus and PFS; NPY is diminished in persons with PTSD/CPTSD and those exposed to chronic stress






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






17. Most pervasive excitatory neurotransmitter in the brain






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






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. Is generated by photoreceptors that are only sensitive to degrees of brightness; black-and-white vision found in the rods






21. Cumulative effects of repeated stimulation from a presynaptic neuron






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






23. Automatic and rapidly acquired reactions - not attributable to reinforcement or conditioning






24. Is used to treat Parkinson'S Disease






25. learning and memory -neurotransmitter released at the neuromuscular junction of skeletal muscle axons to excite the muscle to contract






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






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






28. The restorative effect of introducing a new female sex partner to a male that has apparently become 'exhausted' by sexual activity






29. If a synapse is active at about the same time that a postsynaptic neuron is active - that synapse will be strengthened






30. 'little net'






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






32. Actually are two kinds: monochorionic and dichorionic (blastocyst splis into two before day 4)






33. Norepinephrine and serotonin






34. Contains delta activity - stages III and IV






35. The scientific study of animal behavior; documentation of species-specific instinctual behaviors






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






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






38. Sleepwalking - sleep talking






39. 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)






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






41. Decreasing effects of a medication due to repeated administration






42. An ovary or teste






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






44. 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






45. Midbrain - medulla and the pons






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