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






2. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






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






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






5. The female reproductive cycle of mammals other than primates






6. 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






7. Cumulative effects of repeated stimulation from a presynaptic neuron






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






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






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






11. Facial Nerve - moves face and salivates






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. Viscous substance between cornea and lens; transparent substance between lens and retina






14. Symptom of narcolepsy - irresistible urge to






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






16. Transparent substance between lens and retina






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






18. Accessory Nerve - moves the head






19. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






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






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






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






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






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






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






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






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






28. Is used to treat Parkinson'S Disease






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






30. Has two lobes that are connected by the massa intermedia (looks like a pair of balls - without the nutsack)






31. 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






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. Include tolerance (possible withdrawal) and sensitivity






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






35. Attaches to a binding site on receptor and interferes with the action of the receptor without affecting the binding site for the principal ligand (noncompetitive binding)






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






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






38. Also known as ABLATION - is any surgically induced brain lesion






39. The increase in REM sleep seen after a period of REM sleep deprivation






40. 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






41. 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

42. Auditory receptor cells in the cochlea that turn sound vibrations -> neural impulses






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






44. Most pervasive excitatory neurotransmitter in the brain






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






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






47. 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






48. 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






49. Occurs during the deepest stages of slow-wave sleep; regular - synchronous electrical activity of less than 4 Hz






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