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






3. Is found in the interior rostral temporal lobe - part of limbic system






4. Emotional perception and expression (particularly fearful emotions and detection of threat)






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






6. Midbrain - medulla and the pons






7. Symptom of narcolepsy; complete paralysis that occurs while AWAKE/conscious; will suddenly fall to floor paralyzed for a few minutes






8. Include indolamines (serotonin) and catecholamines (dopamine - norepinephrine and epinephrine)






9. Abducens Nerve - moves eye






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






11. Glossopharyngeal Nerve - taste swallow






12. A 90-minute activity cycle occurs throughout the day as well as throughout sleep (in humans) waxing and waning alertness controlled by a biological clock in the caudal brainstem that also controls cycles of REM and slow-wave sleep






13. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






14. Is an oversensitivity to dopamine (D2)






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






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






17. Supernormal






18. Is found at the base of the brain - underneath the thalamus (**remember hypo-below)






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






20. Projects to ventral tegmental area






21. 'covering'






22. Colored part of the eye






23. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






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






25. Attaches to a binding site on receptor and interferes with the action of the receptor without affecting the binding site for the principal ligand (noncompetitive binding)






26. 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)






27. 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






28. Made from within - natural






29. 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






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






31. If head is rotated - eye movements occur in the same direction






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






34. Consummatory stimulus






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






36. Norepinephrine and serotonin






37. These cells perform a variety of functions but do not transmit information; one type forms the myelin sheath






38. Decreasing effects of a medication due to repeated administration






39. Expression of traits






40. 'Roof'






41. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






42. 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






43. 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






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






45. Is increased in its production by training/experience and therefore - associated with memory






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






47. Olfactory Nerve - smell






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






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






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