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






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

3. 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)






4. 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






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






6. 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)






7. The viscous substance between cornea and lens






8. 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






9. Adenine - Guanine - Thymine - Cytosine






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






11. 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






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






13. A BEHAVIOR; insistent urge of sleepiness forces us to seek sleep/a bad






14. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






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






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






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






18. Self-dissolving






19. 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)

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






21. Referred to as the satiety center; lesions lead to obesity and hyperphagia






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






23. 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






24. A region of the visual association cortex located in the extrastriate cortex at the base of the brain that has special face-recognizing circuits (more important in right hemisphere)






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






26. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






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






28. 'Roof'






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






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






31. Abducens Nerve - moves eye






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






33. Has neurons for reflexes






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






35. 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






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






37. Is used to treat Parkinson'S Disease






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






39. Is characteristic of indirect antagonists






40. Is used as an anaesthetic for children and animals but causes psychosis in adults






41. Motor neurons found in the Somatic (voluntary) and Autonomic (involuntary) Nervous Systems






42. Measure changes in the electrical resistance of the skin (sweat gland activity)






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






44. Moving forward






45. Occurs under drug-induced conditions - including excessive use of marijuana; high body temperature - autonomic instability and muscle rigidity






46. The female reproductive cycle of mammals other than primates






47. First described by Descartes - a combination of antagonistic muscle movements (e.g. those involved in walking)






48. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






49. 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






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