- ACCORDING TO: New Nerve Cell for the Adult Brain By: Gerd Kempermann and Fred Gage What is the previous evidence that stem cells did exist in the adult brain? (This should be dated, with a brief explanation of the studies) How do we study neurogenesis in animals? In humans? Where can we find stem cells in the brain? What is so important about these brain structures? (For example: Why do we find excess stem cells in these structures, but not in others?) How can stem cell proliferation be inhibited?

Thus, signaling of the nervous system is a bioelectrochemical process affected by neurotransmitters. Neurotransmitters act on proteins called (2) _______________, which are found on cell membranes in synapses. (3) _______________ are very narrow gaps (20–50 nm) between neurons allowing for chemical transmission via neurotransmitters. The binding of neurotransmitters to pre- and post-synaptic receptors results in changes in the polarization of the cell.
