Neurotrauma & Neuroprotection Laboratory
My lab is interested in understanding the molecular pathophysiology of brain injuries such as traumatic brain injury (TBI) and stroke and in neuroprotection (preventing or limiting the spread of injury). Currently there are no effective neuroprotective drugs that target the injury development that occurs following TBI or stroke. We have been investigating the neuroprotective efficacy of anaesthetics and inert gases such as xenon and argon. The identification of the molecular targets of certain anaesthetics such as xenon has led to the idea of using them as treatments to prevent brain damage in conditions such as traumatic brain injury and hypoxic/ischemic injury such a neonatal asphyxia and post-cardiac arrest brain damage. In my lab we use a variety of approaches to study the molecular actions of anaesthetics and neuroprotectants; these include patch-clamp electrophysiology, site-directed mutagenesis and models of brain injury.

We participated in "Science Uncovered", an event for the general public at London's Natural History Museum in 2012 & 2013. Science Uncovered is the Natural History Museum’s biggest after hours event attended by 8,500 visitors and is part of an EU funded European Researcher's Day with events taking place simultaneuosly throughout Europe. Click here for a news report on the event. You can see photos of our stand.
In April 2013 we participated in the Wonder Festival of Art & Science of the Brain at London's Barbican Centre where we showcased our neuroprotection work. The event was attended by over 5,000 visitors. In May 2013, May 2014 & May 2016 the research group took part in the Imperial Festival in an event attended by 15,000 members of the public and alumni.
We participated in event for Imperial College Alumni & Donors, November 2014. We participated in Imperial Fringe event to launch the Imperial College Annual Report on Animal Research, February 2015. Our lab has done an outreach activity day at Gillespie Primary School on physiology & the brain.
Dr Dickinson worked with the innovative Lab 13 Science Lab at Gillespie Primary on a project on Manuka Honey funded by British Pharmacological Society. The pupils presented at Cheltenham Science Festival in 2015 and the project was featured in The Times, The Mail Online, Science in School and The British Society for Immunology website.
