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. Increases heartrate - dilates/constricts blood vessels - increases blood sugar - produces hormones epinephrine and norepinephrine






2. The synchronization of the menstrual or estrous cycles of a group of females - which occurs only in the presence of a pheromone in a male'S urine






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






4. The female reproductive cycle of mammals other than primates






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






6. Synchronized EEG activity during its deeper stages






7. Occurs for body temperature - blood glucose levels - blood concentration - etc -hormones are important






8. Termination of pregnancy by the odor of a pheromone in the urine of a male other than the one that impregnated the female; first observed in mice






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






10. Sleepwalking - sleep talking






11. Skin senses that register the sensations of pressure - warmth and cold






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






13. Absolute; relative






14. Is found in PTSD/CPTSD patients and persons exposed to chronic stress






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






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






17. 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






18. Is a peptide neurotransmitter and a natural painkiller and antianxiety






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






20. Forebrain -band of nerve fibers connecting the two cerebral hemispheres






21. 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






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






23. Tremors - rigidity of limbs - poor balance and difficulty initiating movements

24. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






25. 'Roof'






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






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






28. Glandular system control center - produces the hormones oxytocin and antidiuretic; functions in both the nervous system and endocrine sytem - In the forebrain - regulates motivated behaviors (eating - drinking - aggression - sexual behavior






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






30. Links the nervous system and endocrine system; comprised of involuntary efferent neurons and divided into the Sympathetic and Parasympathetic branches: Sympathetic Nervous System is involved in the 'fight or flight' response and the Parasympathetic N






31. EEG desynchrony (rapid -irregular waves) - lack of muscle tonus - rapid eye movements - penile erection/vaginal secretion - dreams; EEG synchrony (slow waves) - moderate muscle tonus - slow/absent eye movements - lack of genital activity






32. Trochlear Nerve - moves eye






33. 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)






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






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






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






37. Decreasing effects of a medication due to repeated administration






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






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






40. Sign






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






42. Ventral part of midbrain - includes periaqueductal gray matter - reticular formation - red nucleus - and substantia nigra






43. The increase in REM sleep seen after a period of REM sleep deprivation






44. Lens changes initiated by the ciliary muscles to change the shape of the lens in order to focus image on the retina






45. The maintenance of water balance in the body






46. Affect multiple receptors; highly preferential to which type of receptor they affect






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






48. 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






49. Includes the tectum and tegmentum






50. 'little brain'
