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. 'little net'






2. Instead of one continuum for sex (masculine-feminine) - her work in the presence of both masculine and feminine features/development suggests these are actually two separate continuums (defeminized-feminized and unmasculinized-masculinized)

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






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






5. Combines input from diverse brain regions; receives sensory information/sends motor impulses






6. 'covering'






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






8. 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)






9. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






10. 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






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






12. Self-dissolving






13. Glossopharyngeal Nerve - taste swallow






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






15. Vagus Nerve - heart rate and digestion






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






17. Found in the hypothalamus - function to maintain the water balance in the body






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






19. Controls sexual activity






20. Can occur after long term antipsychotic tx (opposite of Parkinson'S?); oversensitivity to dopamine






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






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






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






24. Adenine - Guanine - Thymine - Cytosine






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






26. Part of a glial cell that wraps around the axon of a neuron - providing insulation that facilitates speed of propagation of action potential






27. Includes the tectum and tegmentum






28. An inherited form of defective color vision in which hues with short wavelengths are confused (blue cone dysfunction); see world in green and red






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






30. Has neurons for reflexes






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






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






33. Caudate nucleus and putamen






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






35. Accessory Nerve - moves the head






36. 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)






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






38. 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






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






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






41. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






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






43. Activates one of 5 types of receptors in the CNS - cognition - motor activity - reward - muscle tone - sleep - mood - attention - learning -higher level effects of dopamine = D2






44. 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






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






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






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






48. Found in the ventricles and spinal canal






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






50. Facial Nerve - moves face and salivates
