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. Hormone secreted during the night by the pineal body; role in circadian and seasonal rhythms






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






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






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






5. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






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






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






8. A patient who had intact intelligence but an inability to learn/remember anything new (severe anterograde amnesia)






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






10. Is the primary inhibitory neurotransmitter in vertebrates; these receptors are ionotropic






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






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






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






14. The viscous substance between cornea and lens






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






16. Is found in PTSD/CPTSD patients and persons exposed to chronic stress






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






18. Glossopharyngeal Nerve - taste swallow






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






20. An inherited form of defective color vision in which hues with short wavelengths are confused (blue cone dysfunction); see world in green and red






21. Located in the midbrain - a group of neurons which produce dopamine and degenerate in Parkinson'S Disease






22. Norepinephrine and serotonin






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






24. An ovary or teste






25. An area that combines input from diverse brain regions






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






27. Abducens Nerve - moves eye






28. The slowing and eventual cessation of estrous cycles in groups of female animals that are housed together; caused by a pheromone in the animals urine and first observed in mice






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






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






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






32. Is characteristic of indirect antagonist drugs






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






34. 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)






35. Includes the tectum and tegmentum






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






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






38. Vestibulocochlear Nerve - hearing and balance






39. Occurs intermittently during early stages of slow-wave sleep and REM sleep 3.5-7.5 Hz






40. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in prefrontal cortex






41. Contains receptors to detect when the body needs food or fluids; the hunger center; lesions lead to aphagia






42. Expression of traits






43. Short bursts of waves 12-14 Hz that occur 2-5 times a minute during stages 1-4 of sleep; most characteristic of sleep Stage II; some believe sleep spindles are involved in keeping one asleep (decline in older people)






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






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






46. Has a calcium-related role and produces the hormone parathyroid






47. Self-dissolving






48. Functions in metabolism (carbohydrate - protein - lipid) and in the endocrine system'S salt/water balance - produces the hormones cortisol and aldosterone






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






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