But a team of scientists has discovered that cells from other parts of the body also perform a memory function, opening new pathways for understanding how memory works and creating the potential to enhance learning and to treat memory-related afflictions.\u00a0<\/strong><\/p>\n<p>\u201cLearning and memory are generally associated with brains and brain cells alone, but our study shows that other cells in the body can learn and form memories, too,\u201d explains New York University\u2019s\u00a0Nikolay V. Kukushkin, the lead author of the\u00a0study, which appears in the journal\u00a0<em>Nature Communications<\/em>.\u00a0<\/p>\n<p>The research sought to better understand if non-brain cells help with memory by borrowing from a long-established neurological property\u2014the massed-spaced effect\u2014which shows that we tend to retain information better when studied in spaced intervals rather than in a single, intensive session\u2014better known as cramming for a test.<\/p>\n<p>In the\u00a0<em>Nature Communications<\/em>\u00a0research, the scientists replicated learning over time by studying two types of non-brain human cells in a laboratory (one from nerve tissue and one from kidney tissue) and exposing them to different patterns of chemical signals\u2014just like brain cells are exposed to patterns of neurotransmitters when we learn new information.<\/p>\n<p>In response, the non-brain cells turned on a \u201cmemory gene\u201d\u2014the same gene that brain cells turn on when they detect a pattern in the information and restructure their connections in order to form memories.<\/p>\n<p>To monitor the memory and learning process, the scientists engineered these non-brain cells to make a glowing protein, which indicated when the memory gene was on and when it was off.<\/p>\n<p>The results showed that these cells could determine when the chemical pulses, which imitated bursts of neurotransmitter in the brain, were repeated rather than simply prolonged\u2014just as neurons in our brain can register when we learn with breaks rather than cramming all the material in one sitting.<\/p>\n<p>Specifically, when the pulses were delivered in spaced-out intervals, they turned on the \u201cmemory gene\u201d more strongly, and for a longer time, than when the same treatment was delivered all at once.<\/p>\n<p>\u201cThis reflects the massed-space effect in action,\u201d says Kukushkin, a clinical associate professor of life science at NYU Liberal Studies and a research fellow at NYU\u2019s Center for Neural Science.<\/p>\n<p>\u201cIt shows that the ability to learn from spaced repetition isn\u2019t unique to brain cells, but, in fact, might be a fundamental property of all cells.\u201d<\/p>\n<p>The researchers add that the findings not only offer new ways to study memory, but also point to potential health-related gains.<\/p>\n<p>\u201cThis discovery opens new doors for understanding how memory works and could lead to better ways to enhance learning and treat memory problems,\u201d observes Kukushkin.<\/p>\n<p>\u201cAt the same time, it suggests that in the future, we will need to treat our body more like the brain\u2014for example, consider what our pancreas remembers about the pattern of our past meals to maintain healthy levels of blood glucose or consider what a cancer cell remembers about the pattern of chemotherapy.\u201d<\/p>\n<p>The work was jointly supervised by Kukushkin and Thomas Carew, a professor in NYU\u2019s Center for Neural Science.

We now demonstrate this effect in two separate non-neural, immortalized cell lines stably expressing a short-lived luciferase reporter controlled by a CREB-dependent promoter.<\/p>\n<p>We emulate training using repeated pulses of forskolin and\/or phorbol ester, and, as a proxy for memory, measure luciferase expression at various points after training.<\/p>\n<p>Four spaced pulses of either agonist elicit stronger and more sustained luciferase expression than a single \u201cmassed\u201d pulse.<\/p>\n<p>Spaced pulses also result in stronger and more sustained activation of molecular factors critical for memory formation, ERK and CREB, and inhibition of ERK or CREB blocks the massed-spaced effect.<\/p>\n<p>Our findings show that canonical features of memory do not necessarily depend on neural circuitry, but can be embedded in the dynamics of signaling cascades conserved across different cell types.<\/p>\n<p> <!-- Form created by Optin Forms plugin by WPKube: create beautiful optin forms with ease! --> <!-- https:\/\/wpkube.com\/ --><!--optinforms-form5-container--> <!-- \/ Optin Forms --> <\/div>\n<p><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3711241968723425\"\r\n     crossorigin=\"anonymous\"><\/script>\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-format=\"fluid\"\r\n     data-ad-layout-key=\"-fb+5w+4e-db+86\"\r\n     data-ad-client=\"ca-pub-3711241968723425\"\r\n     data-ad-slot=\"7910942971\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><br \/>\n<br \/><div data-type=\"_mgwidget\" data-widget-id=\"1660802\">\r\n<\/div>\r\n<script>(function(w,q){w[q]=w[q]||[];w[q].push([\"_mgc.load\"])})(window,\"_mgq\");\r\n<\/script>\r\n<br \/>\n<br \/><a href=\"https:\/\/neurosciencenews.com\/organ-cell-memory-genetics-28004\/\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Summary: New research reveals that cells outside the brain can store and process memories, challenging the view that memory is limited to neurons.
