Brain Drain
Scientists want to know how the glymphatic system sluices out waste from the central nervous system, acting like a drain for harmful waste. Yet watching the flow of cerebrospinal fluid around the brain is challenging. A new technique called 3D-PAULM combines an advanced form of photoacoustic imaging with ultrasound localisation microscopy to produce super resolution images of cerebrospinal fluid flow patterns. In these mouse brains (pictured from different angles on different rows) 3D-PAULM reveals high fluid flow in brighter regions, with warmer colours showing fluid close to the surface and cooler colours deeper in the tissue. While all three mice are anaesthetised, the flow is much lower in old mice (right) compared to young (left). A more intense form of anaesthesia disrupts cerebrospinal fluid flow, even in young mice (middle), suggesting 3D-PAULM could detect changes in the efficiency of the glymphatic system brought by the environment, ageing or disease.

Movement of the eyes, head, and neck plays a powerful role in supporting the flow of cerebrospinal fluid through the system. This isn’t just passive, it’s driven in part by the deep connections between the muscles and the nervous system. The suboccipital muscles at the base of the skull link directly into the dura mater through what are known as myodural bridges (MDBs). Every time the head or eyes move, these tiny but significant connections create subtle tension and release through the dura, helping to influence fluid movement around the brain and spinal cord. It’s a great reminder that movement, especially precise, controlled movement, isn’t just about muscles and joints, it’s about supporting the brain and nervous system at a much deeper level.

Try this exercise: Sitting down, relax your shoulders, and place your tongue gently on the roof of your mouth. Keep your head still and slowly move your eyes all the way to the right, hold for 5–10 seconds, then back to centre. Repeat to the left. Now add a slow head turn to the right while your eyes stay fixed on a point in front of you, then return to centre, and repeat to the left. As you do this, breathe slowly through your nose and notice any shifts in tension at the base of your skull. This combination of eye, head, and neck movement gently stimulates those deep connections into the dura, helping to regulate the nervous system and support fluid movement around the brain. It’s subtle, but done right, it can feel like a full nervous system reset.
