> because between cells the signaling is based on chemicals that flow through some liquid. The signaling is not even electric. There are some electrical synapses (gap junctions) between neurons and between astrocytes (which are a key part of computation based on more recent research). Also, the electromagnetic field around the cells influences cell activity, and that field has various types of waves that appear to be specific to different types of activity (still unknown if it's a cause or an effect).
