Credit: Neuroscience News<\/figcaption><\/figure>\n<p>Interneurons work a bit like the brain\u2019s traffic controllers where they regulate the firing of other brain cells, acting like a sophisticated brake system.<\/p>\n<p>This control is critical because when interneurons behave differently, it can contribute to neurological conditions like epilepsy, autism, and schizophrenia.<\/p>\n<p>The team studied interneurons in mice and looked at a brain region crucial for learning and memory within the hippocampus. They used advanced brain imaging and light-activated cell techniques.<\/p>\n<p>During quiet, restful periods, they found that activating a single interneuron triggered a coordinated response across other brain cells\u2014a short burst of synchronized\u00a0brain activity. This happened without disturbing the existing organization of the brain cells.<\/p>\n<p>Activating a single interneuron weakened the brain\u2019s \u201cstop\u201d signals which then allowed groups of\u00a0brain cells\u00a0to fire together.
