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






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






3. Is found between the dura mater and arachnoid mater meninges






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






5. 1. ventral tegmentum to mesolimbic forebrain (cognition - reward systems - emotional behavior) 2. substantia nigra to caudate nucleus putamen (movement and sensory stimulation) 3. hypothalamus to pituitary gland (neuronal/hormonal control)






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






7. Viscous substance between cornea and lens; transparent substance between lens and retina






8. Located in the forebrain - basal ganglia -> movement -speech and other complex behaviors






9. Functions as both a hormone and a neurotransmitter in the brain






10. Midbrain - medulla and the pons






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






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






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






14. Abducens Nerve - moves eye






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






16. The female reproductive cycle of mammals other than primates






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






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






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






20. Sits just above the hindbrain - contains cranial nerves - parts of the reticular formation -important relay stations for sensory information and the substantia nigra






21. Completely disactivates the prefrontal cortex (PFC); due to high levels of norepinephrine (NE)






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






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






24. Contains delta activity - stages III and IV






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






27. Has two lobes that are connected by the massa intermedia (looks like a pair of balls - without the nutsack)






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






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






30. Thymoleptics = relieves mania of bipolar disorder (lithium carbonate - valproic acid - carbamazepine)






31. 'little net'






32. Decreasing effects of a medication due to repeated administration






33. Supernormal






34. Synchronized EEG activity during its deeper stages






35. Damage to this are causes clumsiness and loss of balance






36. Is found in the frontal lobe (which is divided into the prefrontal lobes and ___ ___)






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






38. Glossopharyngeal Nerve - taste swallow






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






40. Serotonin = 5-HT -regulation of mood - anxiety - aggression - sleep - appetite - sexuality -rostral and caudal raphe nuclei






41. 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






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






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






44. Receptors whose activation directly affects potassium or chloride ion channels in the neuron - (many drugs of abuse substitute for natural GABA- alcohol - benzos - barbituates






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






46. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






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






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






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






50. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)
