I must tune in my axons, quickly.

Nicotine activated the proteins that we think are on the axon

not good news?

tidbit2

the idea I get from this is that the nicotine is a stimulant
so it raises the volume or stimulates ,so maybe the same happens with caffeine or during meditation.

Scientists know that information travels between brain cells along hairlike extensions called axons. For the first time, researchers have found that axons don’t just transmit information – they can turn the signal up or down with the right stimulation.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.physorg.com/news106749455.html"><DIV>
