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






2. Is a receptor blocker; binds with a receptor but does not activate it - actually prevents the natural ligand from binding with the receptor






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


4. Are found in the diencephalon






5. 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






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






7. Projects to ventral tegmental area






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






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






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






11. Areas in the brain receiving incoming sensory information or sending out motor-impulse commands






12. Vision: protrusions on top of the midbrain; part of visual system






13. In the CNS - is an amino acid that stabilizes neural activity






14. Abducens Nerve - moves eye






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






16. Part of limbic system; protrusion of the bottom of the brain at the posterior end of the hypothalamus - contains some hypothalamic nuclei






17. Associated with (spoken) language reception/comprehension - memory processing - and emotional control; contains Wernicke'S area and the auditory cortex






18. Receive incoming sensory information or send out motor impulse commands






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






20. Involved in the effects of odors/pheromones in reproductive behavior - a nucleus that receives olfactory information from the olfactory bulb and accessory olfactory bulb






21. Is everything anterior to the central sulcus






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






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






24. Olfactory Nerve - smell






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






26. Has neurons for reflexes






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






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. Includes the tectum and tegmentum






30. Cumulative effects of repeated stimulation from a presynaptic neuron






31. Made from within - natural






32. Acquired language disorders - usually caused by damage in the left hemisphere; includes Broca'S: (left frontal lobe damage) and Wernickes'S (left temporal/parietal damage)






33. Important to motor system






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






35. A BEHAVIOR; insistent urge of sleepiness forces us to seek sleep/a bad






36. Sleepwalking - sleep talking






37. 'Roof'






38. Trigerminal Nerve - face sensation






39. The female reproductive cycle of mammals other than primates






40. ...






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






42. Refers to both the somatosensory cortex and motor cortex (they are a little different but very interrelated)






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






44. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in prefrontal cortex






45. Most pervasive excitatory neurotransmitter in the brain






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






47. Consummatory stimulus






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






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






50. 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)
