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. Hypothalamic-pituitary-adrenal axis -controls stress response






2. Receive incoming sensory information or send out motor impulse commands






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






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






5. Audition: protrusions on top of midbrain; part of auditory system






6. 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)






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






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






9. Thymoleptics = relieves mania of bipolar disorder (lithium carbonate - valproic acid - carbamazepine)






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






11. Sleepwalking - sleep talking






12. 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)

13. Most pervasive excitatory neurotransmitter in the brain






14. Glandular system control center - produces the hormones oxytocin and antidiuretic; functions in both the nervous system and endocrine sytem - In the forebrain - regulates motivated behaviors (eating - drinking - aggression - sexual behavior






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






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






17. Include tolerance (possible withdrawal) and sensitivity






18. Holds the lens in place






19. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






20. If head is rotated - eye movements occur in the same direction






21. 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






22. 'Roof'






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






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






25. Having two copies of each chromosomes in most cells (except the gametes) - e.g. most mammals






26. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






27. Lesions to this brain structure that is crucial to memory will produce anterograde amnesia






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






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






30. 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






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






32. 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






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






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






35. The visual image of the world on the retina






36. Olfactory Nerve - smell






37. Adenine - Guanine - Thymine - Cytosine






38. Auditory receptor cells in the cochlea that turn sound vibrations -> neural impulses






39. Is everything anterior to the central sulcus






40. Is characteristic of indirect antagonist drugs






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






42. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in prefrontal cortex






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






44. A sensory organ that detects the presence of certain chemicals - especially when a liquid is actively sniffed; mediates the effects of some pheromones






45. A peptide - also known as OREXIN - produced by neurons whose cell bodies are located in the hypothalamus; their destruction causes narcolepsy






46. AKA the striate cortex - located at the back of the brain - and contains the visual cortex






47. Links the nervous system and endocrine system; comprised of involuntary efferent neurons and divided into the Sympathetic and Parasympathetic branches: Sympathetic Nervous System is involved in the 'fight or flight' response and the Parasympathetic N






48. A region of the visual association cortex located in the extrastriate cortex at the base of the brain that has special face-recognizing circuits (more important in right hemisphere)






49. ...






50. 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
