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. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






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






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






4. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell






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






6. A single - unfertilized cell created during conception; the combined egg + sperm






7. 'little brain'






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






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






10. 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






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






12. The slowing and eventual cessation of estrous cycles in groups of female animals that are housed together; caused by a pheromone in the animals urine and first observed in mice






13. Include tolerance (possible withdrawal) and sensitivity






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






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






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






17. Controls circadian rhythms - produces melatonin (daylight signals go to the eyes to the hypothalamus to the pineal gland)






18. 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)






19. Affect sex characteristics/development and produce estrogen/progesterone (in females - ovaries) and testosterone (in male - testes)






20. Include the Nigrostriatal system - Mesolimbic system and Mesocortical system






21. Occurs when their is damage to the septal area and results in unchecked aggressive and vicious behavior






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






23. Holds the lens in place






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






25. Expression of traits






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






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






28. 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)






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






30. There are 12 add more






31. Affect multiple receptors; highly preferential to which type of receptor they affect






32. Contains receptors to detect when the body needs food or fluids; the hunger center; lesions lead to aphagia






33. Is a loss of dopamine cells in the substantia nigra of the basal ganglia; these cells are usually dark (nigra) but in Parkinson'S - the substantia nigra appears white due to cell death

34. If a synapse is active at about the same time that a postsynaptic neuron is active - that synapse will be strengthened






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






36. Is an oversensitivity to dopamine (D2)






37. Controls sexual activity






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






39. Eating - sex - aggression - sleep - focus on subcortical and neuroendocrine control of behavior






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






41. Research indicates that the expressing of negative emotions is associated with increased immune function; inhibiting negative emotions with decreasing immune function






42. Opening in the iris; dilates and contracts allowing different levels of light in






43. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






44. Precursor to the catecholamine neurotransmitters (DA + NE)






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






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






47. 1. Stage I (non-REM sleep) 2. Stage II (non-REM sleep 3. Stage III (non-REM sleep - slow-wave sleep) 4. Stage IV (non-REM sleep - slow-wave sleep) 5. Rapid Eye Movement Sleep (REM sleep) ~takes about 90 minutes for one full sleep cycle






48. Binding of drug to receptor site that doesn'T interfere with the principal ligand






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






50. Transparent substance between lens and retina
