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. In the posterior frontal lobe - contains the somatosensory cortex (touch - pressure - temperature - pain)






2. Is the primary inhibitory neurotransmitter in vertebrates; these receptors are ionotropic






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






4. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






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






6. 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






7. 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)






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






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






10. A patient who had intact intelligence but an inability to learn/remember anything new (severe anterograde amnesia)






11. Occurs under drug-induced conditions - including excessive use of marijuana; high body temperature - autonomic instability and muscle rigidity






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






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






14. 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






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






16. Has a major role in metabolism - stimulation/maintenance - produces the hormones thyroxin and calcitonin






17. 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






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






19. The Lee-Boot effect - Whitten effect - Vandenbergh effect - and the Bruce effect; all mediated by the VNO






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






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






22. There are 12 add more






23. Includes the tectum and tegmentum






24. Oculomotor Nerve - moves eye pupil






25. Convoluted of hills (gyri) and valleys (sulci) divided into two hemispheres (left and right) which are further divided into four lobes (occipital - parietal - temporal and frontal)






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






27. Colored part of the eye






28. Functions in metabolism (carbohydrate - protein - lipid) and in the endocrine system'S salt/water balance - produces the hormones cortisol and aldosterone






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






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






31. An area that combines input from diverse brain regions






32. 'little brain'






33. Vagus Nerve - heart rate and digestion






34. Regulates body temperature






35. Some brain communications are with the same side of the body






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






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






38. Caudate nucleus and putamen






39. Hormones that reduce pain






40. Projects to ventral tegmental area






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






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






43. Olfactory Nerve - smell






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






45. Attaches to the binding site on a receptor and interferes with the receptor'S action - but NOT by interfering with the principal ligand'S binding site (noncompetitive binding)






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






47. Is regulated by the hypothalamus






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






49. A large network of neural tissue located in the central region of the brain stem - from the medulla to the diencephalon






50. Occurs when an external stimulation - regardless of intensity - will not trigger a new action potential
