Is there a source?

That synapses get physically get close as their interaction increases.

I have also read that where neurons crosses each other they create new neuron, is that true?

  • $\begingroup$ 1. What do you mean with interaction? Synaptic mechanisms? 2. No, as new neurons are born only in restricted areas of the nervous system. $\endgroup$ – AliceD Nov 10 '15 at 21:13

    $\begingroup$ I think you're talking about Hebbian theory? My neuro professor used to summarize this as "Cells that fire together, wire together" (although apparently he was in fact quoting Carla Shatz). $\endgroup$ – tel Nov 10 '15 at 21:14

  • $\begingroup$ " the synapses grow closer together in order to decrease the distance the electrical charge has to cross. " $\endgroup$ – Muhammad Umer Nov 11 '15 at 15:05
  • $\begingroup$ The first red flag is that this sentence is incorrect, based on the explanation following it in the source you linked. It suggests that there would be a reduced distance from one synapse to the next, while the text really explains that there will be a reduction in the width of the synaptic cleft. I am not certain enough to give an answer, but the sloppy language alone makes me think the author does not know what he's talking about. $\endgroup$ – rumtscho Nov 12 '15 at 18:51
