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






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






3. Located in the forebrain - basal ganglia -> movement -speech and other complex behaviors






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






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






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






7. Glossopharyngeal Nerve - taste swallow






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. Trigerminal Nerve - face sensation






10. Bunch of dopaminergic neurons starting in the substantia nigra and ending in the neostriatum






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






12. Symptom of narcolepsy - irresistible urge to






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






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






15. Most pervasive excitatory neurotransmitter in the brain






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






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






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






19. 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






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






21. If head is rotated - eye movements occur in the same direction






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






23. Made from within - natural






24. 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






25. 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

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






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






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






29. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






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






31. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






32. Is an oversensitivity to dopamine (D2)






33. Regulates body temperature






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






35. Self-dissolving






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






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






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






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






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






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






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






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






44. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






45. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






46. Affect multiple receptors; highly preferential to which type of receptor they affect






47. 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






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






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






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