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. 'little brain'






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






3. Is used to treat Parkinson'S Disease






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






5. Adenine - Guanine - Thymine - Cytosine






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






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






8. 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)

9. Abducens Nerve - moves eye






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






11. Is generated by photoreceptors that are only sensitive to degrees of brightness; black-and-white vision found in the rods






12. Includes the tectum and tegmentum






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






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






15. Controls sexual activity






16. Self-dissolving






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






18. Vestibulocochlear Nerve - hearing and balance






19. One of the primary noradrenergic nuclei whose ascending axons project to frontal cortex - thalamus - hypothalamus - limbic system






20. Tremors - rigidity of limbs - poor balance and difficulty initiating movements

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






22. An area that combines input from diverse brain regions






23. Is found in the frontal lobe (which is divided into the prefrontal lobes and ___ ___)






24. 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






25. hormone - secreted by the pituitary gland -signals the adrenal gland to secrete corticosteroid hormones -ACTH is a critical component of the HPA Axis that controls the stress response






26. Refers to both the somatosensory cortex and motor cortex (they are a little different but very interrelated)






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






28. Actually are two kinds: monochorionic and dichorionic (blastocyst splis into two before day 4)






29. 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

30. Important to motor system






31. These two developed the criteria for habituation; basic process is a form of synaptic depression that occurs presyntaptically.






32. 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






33. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






34. Is increased in its production by training/experience and therefore - associated with memory






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






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






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






38. 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






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






40. 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






41. 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






42. Includes comparative (evolution/genetics/animal behavior/ethology) and behavioral regulation






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






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






45. Binding of a drug to a receptor site that does not interfere with the binding site for the principal ligand






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






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






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






49. Colored part of the eye






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