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






2. 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






3. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






4. The female reproductive cycle of most primates - including humans; recognized by growth of the lining of the uterus - ovulation - development of a corpus luteum - and (if pregnancy does not occur) menstration






5. First described by Descartes - a combination of antagonistic muscle movements (e.g. those involved in walking)






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






7. Has neurons for reflexes






8. There are 12 add more






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






10. Portion of a sensory field to which a cell responds






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






12. Related to plasticity - the term Lashley used to describe different parts of the cortex being interchangeable in their roles in learning






13. 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






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






15. 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






16. 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






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






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






19. Hypoglossal Nerve - moves the tongue






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






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






22. 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






23. 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






24. Expression of traits






25. Is regulated by the hypothalamus






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






27. Is the primary inhibitory neurotransmitter in vertebrates; these receptors are ionotropic






28. Those biological considerations which are DISTANT; Evolutionary Psychology - Comparative Psychology - Ethology






29. Holds the lens in place






30. Viscous substance between cornea and lens; transparent substance between lens and retina






31. 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)






32. Self-dissolving






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






34. Cumulative effects of repeated stimulation from a presynaptic neuron






35. 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






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






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






38. Olfactory Nerve - smell






39. Occurs during the deepest stages of slow-wave sleep; regular - synchronous electrical activity of less than 4 Hz






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






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






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






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






44. Vision: protrusions on top of the midbrain; part of visual system






45. Consummatory stimulus






46. Caudate nucleus and putamen






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






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






49. An ovary or teste






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