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






2. 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






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






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






5. Hypothalamic-pituitary-adrenal axis -controls stress response






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






7. Focuses light waves on the retina and is held in place by the suspensory ligament; aqueous humor on cornea side; vitreous humor on retina side






8. Occurs for body temperature - blood glucose levels - blood concentration - etc -hormones are important






9. Emotional perception and expression (particularly fearful emotions and detection of threat)






10. A patient who had intact intelligence but an inability to learn/remember anything new (severe anterograde amnesia)






11. 'little brain'






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






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






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






15. Is used as an anaesthetic for children and animals but causes psychosis in adults






16. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






17. 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)






18. 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)






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






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






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






22. Occur in amacrine - bipolar and horizontal cells; govern/encompass the opponent-process level of color vision






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






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






25. Cumulative effects of repeated stimulation from a presynaptic neuron






26. Reduces anxiety - released with NE in amygdala - hippocampus - basal ganglia - periaqueductal gray region - locus coeruleus and PFS; NPY is diminished in persons with PTSD/CPTSD and those exposed to chronic stress






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






28. Midbrain - medulla and the pons






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






30. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






31. Adenine - Guanine - Thymine - Cytosine






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






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






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






35. Include indolamines (serotonin) and catecholamines (dopamine - norepinephrine and epinephrine)






36. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






37. 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)

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






39. Trochlear Nerve - moves eye






40. Is found at the base of the brain - underneath the thalamus (**remember hypo-below)






41. The restorative effect of introducing a new female sex partner to a male that has apparently become 'exhausted' by sexual activity






42. The synchronization of the menstrual or estrous cycles of a group of females - which occurs only in the presence of a pheromone in a male'S urine






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






44. Moving forward






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






46. Hormone secreted during the night by the pineal body; role in circadian and seasonal rhythms






47. Contains receptors to detect when the body needs food or fluids; the hunger center; lesions lead to aphagia






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






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






50. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)
