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. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






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






3. In the limbic system - is a fiber bundle - connects hippocampus with stuff (including the mammillary bodies of the hypothalamus)






4. Are found in the diencephalon






5. SCN = controls circadian rhythms - located directly above the optic chasm in the anterior portion of the hypothalamus - receives input from the eyes which is why light exposure affects our sleep-wake cycles






6. Norepinephrine and serotonin






7. Termination of pregnancy by the odor of a pheromone in the urine of a male other than the one that impregnated the female; first observed in mice






8. Caudate nucleus and putamen






9. There are 12 add more






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






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






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






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






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






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






16. Bunch of dopaminergic neurons starting in the substantia nigra and ending in the neostriatum






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






18. Increasing effects/effectiveness of a medication due to repeated administration






19. Controls sexual activity






20. Is used to treat Parkinson'S Disease






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






22. Supernormal






23. Occurs intermittently during early stages of slow-wave sleep and REM sleep 3.5-7.5 Hz






24. Consummatory stimulus






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






26. Symptom of narcolepsy - irresistible urge to






27. Midbrain - medulla and the pons






28. Hypoglossal Nerve - moves the tongue






29. 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)






30. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






31. Sudden - sharp waveforms found only in Stage II of sleep; spontaneously occur about one per minute but also to unexpected noises






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






33. Oculomotor Nerve - moves eye pupil






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






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






36. Precursor to GABA (the most inhibitory/regulatory/pervasive neurotransmitter)






37. 'little net'






38. Measure changes in the electrical resistance of the skin (sweat gland activity)






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






40. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






41. Sign






42. 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






43. Holds the lens in place






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






45. EEG desynchrony (rapid -irregular waves) - lack of muscle tonus - rapid eye movements - penile erection/vaginal secretion - dreams; EEG synchrony (slow waves) - moderate muscle tonus - slow/absent eye movements - lack of genital activity






46. 'Roof'






47. Expression of traits






48. Is characteristic of indirect antagonist drugs






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






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