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. Midbrain - medulla and the pons






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






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






4. Sleepwalking - sleep talking






5. 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






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






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






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






9. Automatic and rapidly acquired reactions - not attributable to reinforcement or conditioning






10. Holds the lens in place






11. Functions in metabolism (carbohydrate - protein - lipid) and in the endocrine system'S salt/water balance - produces the hormones cortisol and aldosterone






12. Produces acetylcholine. One of the earliest sites of cell death in Alzheimer'S Disease (neurological disorder associated with a deficiency in acetylcholine) is in the basal forebrain






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






14. The maintenance of water balance in the body






15. Convoluted of hills (gyri) and valleys (sulci) divided into two hemispheres (left and right) which are further divided into four lobes (occipital - parietal - temporal and frontal)






16. A single - unfertilized cell created during conception; the combined egg + sperm






17. 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






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






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






20. 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






21. Increasing effects/effectiveness of a medication due to repeated administration






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






23. 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






24. Is characteristic of indirect antagonist drugs






25. Most pervasive excitatory neurotransmitter in the brain






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






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






28. Has neurons for reflexes






29. 'little brain'






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






31. Is found in the interior rostral temporal lobe - part of limbic system






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






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






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






35. Important to motor system






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






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






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






39. 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






40. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






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






42. Activates one of 5 types of receptors in the CNS - cognition - motor activity - reward - muscle tone - sleep - mood - attention - learning -higher level effects of dopamine = D2






43. Choroid Plexus > Ventricle 1 & 2 > Foramen of Monro > Ventricle 3 > Aqueduct of Sylvius > Ventricle 4 > Foramen of Magendie lateral aperture) > Foramina of Luschka (lateral aperture) - subarachnoid space (outside of brain) and spinal cord > re-absorp






44. 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)

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






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






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






48. Symptom of narcolepsy; complete paralysis that occurs while AWAKE/conscious; will suddenly fall to floor paralyzed for a few minutes






49. 'covering'






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