Professor Jon Driver - Telegraph Driver went on to study Experimental Psychology at Oxford University, then spent a year in America with the psychologist Michael Posner before taking up a lectureship at Cambridge. Within eight years of obtaining his doctorate he had been appointed Professor at Birkbeck College, London. In 1998 he was made Professor at the UCL Institute of Cognitive Neuroscience, one of the world's leading centres of research into the processes of cognition, becoming its director in 2004. In recent years two experiments in which he was involved caught the public imagination. In 2004, with Pia Rotshtein, Ray Dolan and others, he monitored the brains of volunteers while they watched Marilyn Monroe morph into Margaret Thatcher and Tony Blair into Pierce Brosnan. The experiment, reported in Nature Neuroscience, established that three parts of the brain are involved in the process of recognition. The first, the inferior occipital gyri at the back of the brain, picks up small physical changes in morphed faces; the second, the right fusiform gyrus (RFG), puts faces into a known or unknown category (and is the part of the brain which tells us "That face rings a bell"); finally, the anterior temporal cortex (ATC) retrieves the name or other facts linked to that face. Damage to any of the three parts of the brain precipitates a crisis of recognition. For example, dementia patients with damage to the ATC have a problem recalling names, while people with epilepsy triggered by the RFG sometimes believe different faces belong to the same person. Meanwhile, when an individual face morphs into that of another individual, the scientists found that the brain tries to pin a single identity to them. So a face that is 60 per cent Marilyn Monroe but 40 per cent Margaret Thatcher will be identified as an older version of the screen goddess, while an image 40 per cent Monroe and 60 per cent Thatcher will be seen as the sexier side of the former Prime Minister. Another experiment addressed a classic illusion called the "cutaneous rabbit" whereby a person, given a rapid succession of taps to the wrist, quickly followed by taps to the elbow, feels a sensation of intervening taps hopping up the arm. In 2006, with Felix Blankenburg and others, Driver showed that even though nothing is bouncing up the limb, increased activity was seen in the brain region corresponding to the middle of the forearm. It was suggested that this connection between conscious perception and events in the brain might help to throw light on the cause of phenomena such as phantom limb pain, when amputees are troubled by sensations from a missing arm or leg. In 2009 Driver was one of only six scientists from around the world selected for a Royal Society Anniversary Research Professorship. In that role, he moved to join close colleagues at the Wellcome Trust Centre for Neuroimaging at UCL. Though he could seem intimidating to people who did not know him well, Driver encouraged his students and researchers to report issues that bothered them - personal or academic - so that he could take steps to address them. He once told a colleague that he believed everyone had the potential for greatness in them, if only they were challenged hard enough and made to feel they had all the support and resources they needed. Many of his students went on to be leading neuroscientists. His vision and drive were central to the team that was successful, in October last year, in securing approval for the creation of a new Sainsbury-Wellcome Centre for Neural Circuits and Behaviour at UCL, which is due to be completed in 2014. Driver was elected a Fellow of the Academy of Medical Sciences in 2005; a member of Academia Europaea in 2006; and a Fellow of the British Academy in 2008. He was an outstanding exponent of the art of fly-fishing and loved the chalk streams of southern England. Jon Driver suffered fatal injuries after jumping from Hornsey Lane Bridge, Archway, north London . He is survived by his wife, Nilli, and by their two children. Professor Jon Driver, born July 4 1962, died November 28 2011
