Ionic channel "icebergs"

As seen in this great neural networks book.

Page 30: 

"In the protoplasm of the cell, ionic channels are produced and replaced continually. They attach themselves to those regions of the neurons where they are needed and can move laterally in the membrane, like icebergs in the sea. The regions of increased neural sensitivity to the production of action potentials are thus changing continuously according to experience."
