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. Includes comparative (evolution/genetics/animal behavior/ethology) and behavioral regulation






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






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






4. Vestibulocochlear Nerve - hearing and balance






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






6. A behavior that has different forms or occurs with different probabilities or under different circumstances in males than females






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






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






9. 'Roof'






10. Made from within - natural






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






12. An ovary or teste






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






14. 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)






15. Dorsal part of midbrain; includes the superior and inferior colliculi






16. Regulates body temperature






17. Caudate nucleus and putamen






18. hormone - secreted by the pituitary gland -signals the adrenal gland to secrete corticosteroid hormones -ACTH is a critical component of the HPA Axis that controls the stress response






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






20. 'covering'






21. Similarity of alleles for a trait in an organism (i.e. heterozygous or homozygous)






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






23. Strip of limbic cortex lying along the lateral walls of the groove separating the cerebral hemispheres - just above the corpus callosum






24. 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)






25. 'little net'






26. Physiologically different from the other four stages of sleep (i.e. the similarity between the summed electrical activity of neurons measured on the scalp (EEG) during REM sleep and during wakefulness






27. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






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






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






30. Expression of traits






31. Ventral part of midbrain - includes periaqueductal gray matter - reticular formation - red nucleus - and substantia nigra






32. Pass the easiest through the blood-brain barrier






33. Motor neurons found in the Somatic (voluntary) and Autonomic (involuntary) Nervous Systems






34. Actually are two kinds: monochorionic and dichorionic (blastocyst splis into two before day 4)






35. Junction of the sagittal and coronal sutures of the skull; often used as a reference point for stereotaxic brain surgery






36. Somewhat excitatory - also involved in synaptic plasticity - learning and short-term memory






37. Symptom of narcolepsy - irresistible urge to






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






39. Result in either tolerance (and possible withdrawal symptoms) or sensitization (increase effectiveness of the drug)






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






41. Contains delta activity - stages III and IV






42. Occurs at the onset of puberty; a hypothalamic hormone that stimulates the pituitary gland to secrete gonadotropin






43. Is found between the arachnoid mater and Pia mater; this is where CSF cushions (and bathes) the brain - giving it the floating quality (and keeping it moist/circulating)






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






45. Transparent substance between lens and retina






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






47. Associated with defensive and aggressive behavior; lesions produce docility and hypersexual states (Kluver & Bucy)






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






49. Cornea - aqueous humor - pupil - lens - vitreous humor - retina






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