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. 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






2. 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)

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






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






5. Contains delta activity - stages III and IV






6. Is regulated by the hypothalamus






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






8. An anterograde amnesia in which one cannot form episodic memories BUT in experiments - patients that cannot identify previously heard melodies do show a preference for them -> explicit memory function has a different neurological basis than implicit

9. 'little net'






10. Moving forward






11. The maintenance of water balance in the body






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






13. Part of limbic system; protrusion of the bottom of the brain at the posterior end of the hypothalamus - contains some hypothalamic nuclei






14. Abducens Nerve - moves eye






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






16. Found in the ventricles and spinal canal






17. Most pervasive excitatory neurotransmitter in the brain






18. Is used to treat Parkinson'S Disease






19. Cumulative effects of repeated stimulation from a presynaptic neuron






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






21. 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






22. Increases heartrate - dilates/constricts blood vessels - increases blood sugar - produces hormones epinephrine and norepinephrine






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






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






25. The viscous substance between cornea and lens






26. Are direct antagonists; binds with a receptor but does not activate it - but prevents the natural ligand from binding with the receptor






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






28. A 90-minute activity cycle occurs throughout the day as well as throughout sleep (in humans) waxing and waning alertness controlled by a biological clock in the caudal brainstem that also controls cycles of REM and slow-wave sleep






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






30. Trochlear Nerve - moves eye






31. Include tolerance (possible withdrawal) and sensitivity






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






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






34. Smooth electrical activity of 8-12 Hz -medium frequency - awake but in a restful state (^ eyes closed but conscious)






35. Found in the hypothalamus - function to maintain the water balance in the body






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






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






38. Is found between the arachnoid mater and Pia mater; this is where CSF cushions (and bathes) the brain - giving it the floating quality (and keeping it moist/circulating)






39. Pass the easiest through the blood-brain barrier






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






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






42. 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






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






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






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






46. Includes the tectum and tegmentum






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






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






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






50. 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
