DESCRIPTION:Prof. Andrew Jackson\, Newcastle University\, UK.\nThe local f
 ield potential (LFP) has many advantages over action potentials for implan
 table neural interfaces\, including low bandwidth and long-term stability.
  However\, the LFP has traditionally been thought to reflect only the acti
 vity of large neuronal populations and therefore convey little information
  about brain networks. I will describe experiments demonstrating that the 
 activity of single neurons can be decoded from multichannel LFPs and used 
 for neurofeedback control of brain activity. In addition I will show how c
 onsistent dynamical features of the LFP can be used to extract movement pa
 rameters that can be used for Brain-Machine Interfaces. Finally I will des
 cribe experiments exploiting LFPs for closed-loop control of optogenetic s
 timulation\, with the aim of developing an optoelectronic device for the s
 uppression of epileptic seizures.\n\nBio: \nMy background combines physics
  (MPhys\, Oxford University\,UK 1994-1998) and Neuroscience (PhD\, Univers
 ity College London\, UK 1998-2002). From 2002 to 2006 I was a research fel
 low at the University of Washington\, US where I developed ‘Neurochip’
  technology for continuous monitoring and manipulation of neural activity.
  In 2006 I moved to Newcastle University where I am now a Professor of Neu
 ral Interfaces and Wellcome Trust Senior Research Fellow at the Institute 
 of Neuroscience. My laboratory conducts electrophysiological studies in no
 n-human primates using implanted electrodes and wearable electronics\, as 
 well as human studies using non-invasive recording (EEG\, EMG) and stimula
 tion (TMS\, TDCS). We study basic neuroscience questions about motor contr
 ol\, the neural correlates of learning\, and brain dynamics during waking 
 and sleep. In addition\, a major interest is clinical applications of clos
 ed-loop neural interfaces in neurological injury and disease\, for example
 \, our work on closed-loop spinal cord stimulation to restore function to 
 the upper-limb\, and the CANDO consortium developing an optoelectronic dev
 ice for closed-loop optogenetic prevention of seizures.\n
