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. 'covering'






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






3. An ovary or teste






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






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






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






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






8. Is found at the base of the brain - underneath the thalamus (**remember hypo-below)






9. Controls sexual activity; lesions inhibit sexual behavior; stimulation increases aggressive sexual behavior






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






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






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






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






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






15. 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)


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






17. 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






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






19. Receptors whose activation directly affects potassium or chloride ion channels in the neuron - (many drugs of abuse substitute for natural GABA- alcohol - benzos - barbituates






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






21. Smooth electrical activity of 8-12 Hz -medium frequency - awake but in a restful state (^ eyes closed but conscious)






22. Vestibulocochlear Nerve - hearing and balance






23. Maintains balance/posture and coordinates body movements






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






25. 'little net'






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






27. Regulates body temperature






28. These two brain structures contain entry/exits for most of the cranial nerves and control vital functions (heart rate -digestion - respiration)






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






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






31. Pleasure center of the brain; discovered by Olds & Milner






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






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






34. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)






35. Research indicates that the expressing of negative emotions is associated with increased immune function; inhibiting negative emotions with decreasing immune function






36. Colored part of the eye






37. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






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






39. Is found in the interior rostral temporal lobe - part of limbic system






40. 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






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






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






43. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






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






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






46. The restorative effect of introducing a new female sex partner to a male that has apparently become 'exhausted' by sexual activity






47. Is characteristic of indirect antagonist drugs






48. States that performance is worst at extremely low or extremely high levels of arousal and optimally at an intermediate level






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






50. Oculomotor Nerve - moves eye pupil
