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. Located underneath the cerebral cortex and includes the bottom portion of the forebrain - cerebellum - basal ganglia - medulla - pons - midbrain - thalamus - hypothalamus - amygdala - hippocampus






2. Has a major role in metabolism - stimulation/maintenance - produces the hormones thyroxin and calcitonin






3. Supernormal






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






5. 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)






6. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






7. Absolute; relative






8. Some brain communications are with the same side of the body






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






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






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






12. Is everything anterior to the central sulcus






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






14. Completely disactivates the prefrontal cortex (PFC); due to high levels of norepinephrine (NE)






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






16. Abducens Nerve - moves eye






17. Facial Nerve - moves face and salivates






18. States that performance is worst at extremely low or extremely high levels of arousal and optimally at an intermediate level






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






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






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






22. If a synapse is active at about the same time that a postsynaptic neuron is active - that synapse will be strengthened






23. 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






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






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






26. Vestibulocochlear Nerve - hearing and balance






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






28. Controls sexual activity






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






30. 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






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






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






33. Dorsal part of midbrain; includes the superior and inferior colliculi






34. 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






35. Made from within - natural






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






37. Attaches to the binding site on a receptor and interferes with the receptor'S action - but NOT by interfering with the principal ligand'S binding site (noncompetitive binding)






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






39. 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






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






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






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






43. 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






44. 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






45. Comprised of the hypothalamus - pituitary gland - thyroid gland - parathyroid - the adrenal cortex - the adrenal medulla - the pancreas - the ovaries/testes - pineal gland.






46. Symptom of narcolepsy - irresistible urge to






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






48. Is an oversensitivity to dopamine (D2)






49. Caudate nucleus and putamen






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