Does playing brain games work on our brains?  What does the research say about these types of games and activities found in our mobile devices?

What is reciprocal inhibition? How does this term relate to “good” and/or “altered” posture?

22.    Neuroimaging research from Gallant Lab showed that the representation of semantic information in the brain was organized in what way? semantic information is represented the thalamus, the “relay station” for language processing semantic information is represented primarily in left inferior frontal gyrus semantic information is represented in activity throughout the cerebral cortex semantic information is represented primarily in posterior and superior temporal lobe (Wernicke’s area)

Researchers investigating the effect of exercise on cognitive functions conducted a con- trolled experiment in which rats were randomly assigned to sedentary (Sed), low-intensity exercise (Low-Ex), or high-intensity exercise (High-Ex) groups. During this exercise regi- ment, rats were also trained to navigate a specialized water maze, and their escape la tency, the time it took them to escape the maze, was recorded. The results of this experi- ment are depicted in the figure below. escape latency (sec) 100 80 60- 40- 20 0- day 10 day 11 Escape latencies during the training phase Based on the data above, day 12 (b) Identify the control group in the experiment. sed -- low-ex -- high-ex (a) Identify the dependent and independent variables in the experiment. day 13 Respond to each part in 3 to 4 complete sentences. (c) Compare the effects of low-intensity and high-intensity exercise on the rats' cognitive func- tion during the training period.
