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






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






3. 'Roof'






4. Are found in the diencephalon






5. Occurs during the deepest stages of slow-wave sleep; regular - synchronous electrical activity of less than 4 Hz






6. Located underneath the cerebral cortex and includes the bottom portion of the forebrain - cerebellum - basal ganglia - medulla - pons - midbrain - thalamus - hypothalamus - amygdala - hippocampus






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






8. Binding of a drug to a receptor site that does not interfere with the binding site for the principal ligand






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






10. Includes the thalamus and hypothalamus; region of forebrain surrounding the 3rd ventricle






11. Begins where spinal cord ends - 3 structures: the medulla - the pons - the cerebellum






12. The female reproductive cycle of most primates - including humans; recognized by growth of the lining of the uterus - ovulation - development of a corpus luteum - and (if pregnancy does not occur) menstration






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






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






15. Transparent substance between lens and retina






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






17. In the limbic system - is a fiber bundle - connects hippocampus with stuff (including the mammillary bodies of the hypothalamus)






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






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






20. Pass the easiest through the blood-brain barrier






21. Choroid Plexus > Ventricle 1 & 2 > Foramen of Monro > Ventricle 3 > Aqueduct of Sylvius > Ventricle 4 > Foramen of Magendie lateral aperture) > Foramina of Luschka (lateral aperture) - subarachnoid space (outside of brain) and spinal cord > re-absorp






22. Accessory Nerve - moves the head






23. An inherited form of defective color vision in which hues with short wavelengths are confused (blue cone dysfunction); see world in green and red






24. 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






25. Regulates body temperature






26. Abducens Nerve - moves eye






27. Is used as an anaesthetic for children and animals but causes psychosis in adults






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






29. 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






30. Important to motor system






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






32. 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






33. Norepinephrine and serotonin






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






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






36. An area that combines input from diverse brain regions






37. An anterograde amnesia in which one cannot form episodic memories BUT in experiments - patients that cannot identify previously heard melodies do show a preference for them -> explicit memory function has a different neurological basis than implicit

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






39. Related to plasticity - the term Lashley used to describe different parts of the cortex being interchangeable in their roles in learning






40. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






41. Optic Nerve - sight






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






43. 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






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






45. Moving forward






46. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






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






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. Is a peptide neurotransmitter and a natural painkiller and antianxiety






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