Time was when the cell body was the telephone mouthpiece and the axon was the telephone cord. Axons just passively conducted the information fed into them like so many cables. But this new article Neurosci. Res. 2013 Sasaki sets forward a summary of recent evidence that astrocytes camped out along the axon modify the signals that cell bodies transmit towards the synapse, making axons cites of information “post processing” rather than the passive conveyors of information. Makes you think (ba-dum)!
