<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">neural junction</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for synapse that I've seen before include "Brain connection" , "Gap between nerve cells across which signals pass" , "It links cells" , "Part of the nervous system" , "Connection between nerve cells" .)
