While it had previously been suggested that 5-HT neurons may rather be connected with one another, it had not been directly demonstrated. That is what we did here. We also identify an intriguing processing role\u2014or a computation\u2014that is supported by this particular type of connectivity between 5-HT neurons,\u201d says Dr. Jean-Claude B\u00e9\u00efque, full professor in the Faculty\u2019s Department of Cellular and Molecular Medicine and co-director of the uOttawa Brain and Mind Research Institute\u2019s Centre for Neural Dynamics and Artificial Intelligence.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Our lives are filled with binary decisions\u2014choices between one of two alternatives.
