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. 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






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






3. Facial Nerve - moves face and salivates






4. Areas in the brain receiving incoming sensory information or sending out motor-impulse commands






5. A peptide - also known as OREXIN - produced by neurons whose cell bodies are located in the hypothalamus; their destruction causes narcolepsy






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






7. 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






8. Norepinephrine and serotonin






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






10. Governs eating/drinking (lateral and ventromedial hypothalami) and sexual activity (anterior portion






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






12. A single - unfertilized cell created during conception; the combined egg + sperm






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






14. Oculomotor Nerve - moves eye pupil






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






16. Neurotransmitter in CNS - hormone in peripheral vascular system; deficiencies > depression - ADD; noradrenergic nuclei = locus coeruleus






17. Holds the lens in place






18. 1. Stage I (non-REM sleep) 2. Stage II (non-REM sleep 3. Stage III (non-REM sleep - slow-wave sleep) 4. Stage IV (non-REM sleep - slow-wave sleep) 5. Rapid Eye Movement Sleep (REM sleep) ~takes about 90 minutes for one full sleep cycle






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






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






21. Sudden - sharp waveforms found only in Stage II of sleep; spontaneously occur about one per minute but also to unexpected noises






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






23. Most pervasive excitatory neurotransmitter in the brain






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






25. Expression of traits






26. Projects to ventral tegmental area






27. ...






28. 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)

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






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






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






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






33. Caudate nucleus and putamen






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






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

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






37. Is found between the dura mater and arachnoid mater meninges






38. Is characteristic of indirect antagonist drugs






39. Accessory Nerve - moves the head






40. Pass the easiest through the blood-brain barrier






41. Physiologically different from the other four stages of sleep (i.e. the similarity between the summed electrical activity of neurons measured on the scalp (EEG) during REM sleep and during wakefulness






42. 'covering'






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






44. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






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






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






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






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






49. Decreases with age up until age 30 - then begins to increase *(counter intuitive)*






50. 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
