All sensory input has pathways that project from the peripheral nervous system to the central nervous system. Which of the following is the correct pathway for our sense of hearin: | cranial nerve VIII-->medulla oblongata->pons->pons->midbrain and thalamus->auditory cortex |
Which of the following statements are true concerning vision? | rods are more numerous than cones, and the oculomotor nerve (III) controls both pupil diameter and lens shape |
Regarding sleep: | dreaming can occur at stage 1 (REM) or stage 4 (deep slow sleep); sleep may help us to "recharge" or allocate sufficient energy to maintain our immune systems; some species, like mammals, can sleep one hemisphere at a time |
Concerning the nervous system: | the autonomic nervous system innervates tissues including cardiac and smooth muscle |

Which of the following CNS regions play a functional role in sexual orientation | hypothalamic nuclei such as the SDN-POA |
Memories are more likely to be created when ____ levels are elevated | epinephrine |
Which of the following senses uses free nerve endings as sensory receptors: | olfaction |
Which of the following is true concerning sensory coding: | as convergence of primary neurons onto secondary neurons increases, acuity decreases |
Pacinian corpuscles and Ruffini corpuscles are examples of | mechanoreceptors |
Awareness of body position in space is known as nociception | false |
olfactory receptors are free nerve endings | true |

Which is true regarding phototransduction | none of the above |
Which of the following is true regarding visual processing | none of the above |
peripheral drift optical illusions make two identical colors look different by using shadow and light | false |
This best explains our ability to localize sound | the neurons carrying auditory input are ipsilateral and contralateral in both the left and right auditory cortex |
Concerning the sensory receptor to the right | it releases neurotransmitter even at rest, it can be found, for example, in the semicircular canals and otolith organs; it is used in hearing and equilibrium pathways |
The sympathetic nervous system is most active during fight or flight whereas the parasympathetic is most active during tend and befriend situations | False |

Two point discrimination tests demonstrate that | touch sensitivity varies over different parts of the body |
____ is when multiple sensory receptors function together to send more highly resolved information into the CNS | population coding |
In the 60 Minutes video, the main point of the Harvard researcher (Dr. Irving Kirsch) central to the story was that | individuaqls taking antidepressants may be getting better, not because of the antidepressant drug they are taking but rather a placebo effect |
In the 60 minutes video, we learned that the FDA testing requirement for psychiatric drugs is that | as long as two studies show a positive effect of a drug, no matter how many show no or negative effect, it can be considered for approval |
