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






2. An area that combines input from diverse brain regions






3. A chemical released by one animal that affects the behavior or physiology of another animal; usually smelled or tasted






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






5. Symptom of narcolepsy - irresistible urge to






6. Means 'Savory' in Japanese and is a taste receptor found on the tongue; activated by glutamate present in meats - cheese and other protein heavy foods






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






8. Accessory Nerve - moves the head






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






10. 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






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






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






13. Are found in the diencephalon






14. These cells perform a variety of functions but do not transmit information; one type forms the myelin sheath






15. An anterograde amnesia in which one cannot form episodic memories BUT in experiments - patients that cannot identify previously heard melodies do show a preference for them -> explicit memory function has a different neurological basis than implicit

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






17. Has neurons for reflexes






18. Colored part of the eye






19. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






20. All have similar molecular structure - so many 'dirty' medications






21. Include tolerance (possible withdrawal) and sensitivity






22. Sleep tests (i.e. to diagnosis sleep apnea)






23. The visual image of the world on the retina






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






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






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






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






29. The earlier onset of puberty seen in female animals that are housed with males caused by a pheromone in the male'S urine and first observed in mice






30. The midbrain; a region that surrounds the cerebral aqueduct; includes tectum and the tegmentum






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






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






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






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






35. The female reproductive cycle of mammals other than primates






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






37. 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)






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






39. These two brain structures contain entry/exits for most of the cranial nerves and control vital functions (heart rate -digestion - respiration)






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






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






42. Supernormal






43. The scientific study of animal behavior; documentation of species-specific instinctual behaviors






44. Includes the tectum and tegmentum






45. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






46. A steroid hormone produced by the ovary that maintains the endometrial lining of the uterus during the later part of the menstrual cycle and during pregnancy; along with estradiol it promotes receptivity in female mammals with estrous cycles






47. 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






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






49. Optic Nerve - sight






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