That is, we will increasingly combine the study of <em>synapse formation between neurons<\/em> with the study of <em>frequency alignment among brain regions<\/em>.<\/p>\n<p>That account will doubtless be more complex. But: if it&#8217;s more accurate, that complexity will ultimately be more helpful to us all.<\/p>\n<h2>Looking Forward to 2nd Grade<\/h2>\n<p>When I was in grad school, <a href=\"https:\/\/en.wikipedia.org\/wiki\/Kurt_W._Fischer\" target=\"_blank\">Kurt Fischer<\/a> often said &#8220;when it comes to understanding brains, we&#8217;re still in first grade.&#8221;<\/p>\n<p>He meant that the brain is just so complicated, we have only just begun to understand it.<\/p>\n<p>For teachers interested in neuroscience, this truth has a powerful consequence. Much of what we learn about the brain today will be understood differently next year.
