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






2. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






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






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






5. 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






6. Synchronized EEG activity during its deeper stages






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






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






9. Vestibulocochlear Nerve - hearing and balance






10. Located in the forebrain - basal ganglia -> movement -speech and other complex behaviors






11. Regulates body temperature






12. Can occur after long term antipsychotic tx (opposite of Parkinson'S?); oversensitivity to dopamine






13. 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






14. Stimulates bone growth and produces the hormones: somatotropin - prolactin - thyroid-stimulating - adrenocorticotropic (ACTH) - follicle-stimulating - luteinnizing






15. Is everything anterior to the central sulcus






16. 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






17. The maintenance of water balance in the body






18. Cumulative effects of repeated stimulation from a presynaptic neuron






19. Include the Nigrostriatal system - Mesolimbic system and Mesocortical system






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






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






22. 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






23. Facial Nerve - moves face and salivates






24. Colored part of the eye






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






26. Is regulated by the hypothalamus






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






28. Combines input from diverse brain regions; receives sensory information/sends motor impulses






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






30. An axon of a neuron in one region of the brain whose terminals form synapses with neurons in another region






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






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






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






34. Strip of limbic cortex lying along the lateral walls of the groove separating the cerebral hemispheres - just above the corpus callosum






35. 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






36. 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






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






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






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






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






41. The earlier onset of puberty seen in female animals that are housed with males caused by a pheromone in the male'S urine and first observed in mice






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






43. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






44. 1. ventral tegmentum to mesolimbic forebrain (cognition - reward systems - emotional behavior) 2. substantia nigra to caudate nucleus putamen (movement and sensory stimulation) 3. hypothalamus to pituitary gland (neuronal/hormonal control)






45. Located in the midbrain - a group of neurons which produce dopamine and degenerate in Parkinson'S Disease






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






47. Decreasing effects of a medication due to repeated administration






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






49. Has two lobes that are connected by the massa intermedia (looks like a pair of balls - without the nutsack)






50. Adenine - Guanine - Thymine - Cytosine
