Answer to Question 1

Certain biomarkers, namely those plasma levels high in B, C, D, and E and those high in omega-3 fatty acids (particularly DHA) were associated with higher cognitive functioning and greater overall brain volume. On the other hand, blood plasma levels high in trans fats were associated with lower cognitive functioning and less total cerebral volume. Overall, the results of these studies indicate that keeping certain levels of specific nutrients in blood plasma enhanced cognitive ability. Researchers are only now beginning to understand the implications of nutrition on cognitive
functioning over time. More research is needed in this area to substantiate and expand these findings.

Answer to Question 2

The brain is made up of neurons. The dendrites are the component of neurons that receive signals from other nearby neurons. The axons contain neurofibers. These neurofibers carry information inside the neuron from the dendrites to the terminal branches, which are the endpoints of the neuron. Terminal branches release chemicals called neurotransmitters. Because neurons do not touch, it is these neurotransmitters that cross the synapse and are received by the dendrites of next nearby neuron.
