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






2. Found that developmental changes occurring in puberty make the brain more susceptible to the psychotic effects of NDMA antagonist and therefore also related to the emergence of symptoms of schizophrenia






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






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






5. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






6. 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






7. Precursor to the catecholamine neurotransmitters (DA + NE)






8. Hypoglossal Nerve - moves the tongue






9. Projects to ventral tegmental area






10. 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






11. 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






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






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






14. Occurs for body temperature - blood glucose levels - blood concentration - etc -hormones are important






15. Vision: protrusions on top of the midbrain; part of visual system






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






17. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






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






19. Affect sex characteristics/development and produce estrogen/progesterone (in females - ovaries) and testosterone (in male - testes)






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






21. Occur in amacrine - bipolar and horizontal cells; govern/encompass the opponent-process level of color vision






22. ...






23. Lesions to this brain structure that is crucial to memory will produce anterograde amnesia






24. Holds the lens in place






25. Is regulated by the hypothalamus






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






27. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






28. Expression of traits






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






30. 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)






31. Includes the thalamus and hypothalamus; region of forebrain surrounding the 3rd ventricle






32. Part of a glial cell that wraps around the axon of a neuron - providing insulation that facilitates speed of propagation of action potential






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






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






35. 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






36. Include tolerance (possible withdrawal) and sensitivity






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






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






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






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






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






42. Accessory Nerve - moves the head






43. Is a peptide neurotransmitter and a natural painkiller and antianxiety






44. Readiness with which molecules/drugs/medications join together; varies widely from medication to medication






45. The synchronization of the menstrual or estrous cycles of a group of females - which occurs only in the presence of a pheromone in a male'S urine






46. Has neurons for reflexes






47. Relays nerve impulses - processes sensory impulses - reflex behavior and contains nerve cell bodies






48. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






49. Is used to treat Parkinson'S Disease






50. Two different presynaptic neurons/inputs to a post-synaptic cell
