Danger! High Voltage!

Standing between school students and their weekends was always going to be a tough gig, but it was #PhysiologyFriday and we were determined to put on a show. Together with Orla and Ioannis, PhD students from the University of Reading, I arrived at East Ham Town Hall and was greeted by over 200 excited students and their teachers.

Our mission was to deliver an engaging session around electricity and pass on an innovative human-human interface educational resource that the students had won as part of a Physiological Society competition, The Science of Life 2016. After a brief introduction to human electricity and how we can detect it, we took the students on a journey from the first electroencephalogram (EEG) to the potential of neuroprosthetics in treating paralysis. We then tackled a live demonstration of the kit and the students were intrigued to see the interface in action.

 

Surely, one human cannot control another’s arm using only their brain activity? The wonders of neuroscience said it should be possible, but we sensed some doubters in the audience. Using the human-human interface Ioannis was going to harness his brain power to move Orla’s arm against her wishes……

Thankfully the demonstration was up to scratch with the students requesting several encores, and even asking for the voltage to be turned up! Normally the complexities of electrophysiology remain in the lab due to expensive and static equipment, however this kit gave us the ability to be mobile and take the dark art of electrophysiology to young minds keen to explore neuroscience. It was well worth it. The students left school for the weekend with a sense of excitement and thirst to learn more. Orla, Ioannis and I left East Ham Town Hall feeling that we had sparked the interest of the next generation of physiologists.
