Homework due 9/9/08 Name ________________________________ Fields, D.R. (April 2004) The other half of the brain. Scientific American. 54-61 1. What did Marion Diamond find to be unusual about the anatomy of Einstein’s Brain? What might this suggest about the role of glia in brain functioning? 2. What type of naturally occurring event in the brain activates Glia cells (i.e. causes calcium entry into the glia cell)? (calcium entry is a signal that increases intracellular metabolism in all cells of the body). How long after this event do glia show activation? 3. What evidence is there that an activated astrocyte (experiencing Ca++ influx) can communicate this activation to other astrocytes? 4. How does an action potential from an axon initially activate astrocytes (what is the messenger)? How can one block the ability of axons to activate astrocytes? How does one astrocyte communicate with another astrocyte? 5. 5. What are Schwann cells and Oligodendrocytes? How might they be influenced early in development by electrical activity in the brain? What does this suggest about the mechanism underlying myelination in the CNS (but not PNS).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
