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. 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






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






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






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






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






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






7. Holds the lens in place






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






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






10. Measure changes in the electrical resistance of the skin (sweat gland activity)






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






12. 'covering'






13. Hormones that reduce pain






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






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






16. Is everything anterior to the central sulcus






17. 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






18. Trigerminal Nerve - face sensation






19. Abducens Nerve - moves eye






20. Sleep tests (i.e. to diagnosis sleep apnea)






21. Somewhat excitatory - also involved in synaptic plasticity - learning and short-term memory






22. Includes the tectum and tegmentum






23. Midbrain - medulla and the pons






24. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






25. 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)






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






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






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






29. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






30. Found in the ventricles and spinal canal






31. Olfactory Nerve - smell






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






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






34. 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






35. Is characteristic of indirect antagonist drugs






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






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






38. Damage to this are causes clumsiness and loss of balance






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






40. Found in the hypothalamus - function to maintain the water balance in the body






41. Attaches to the binding site on a receptor and interferes with the receptor'S action - but NOT by interfering with the principal ligand'S binding site (noncompetitive binding)






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






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






44. 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






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






46. Facial Nerve - moves face and salivates






47. Portion of a sensory field to which a cell responds






48. Focuses light waves on the retina and is held in place by the suspensory ligament; aqueous humor on cornea side; vitreous humor on retina side






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






50. Include tolerance (possible withdrawal) and sensitivity
