  • METHODS: To investigate if this structure processes emotional information, and whether it depends on motor demands, we recorded subthalamic local field potentials in 16 patients with Parkinson's disease using deep brain stimulation electrodes. (mendeley.com)
  • These findings confirm the specific involvement of the STN in emotional processes in human, which may underlie the behavioural changes observed in patients with deep brain stimulation. (mendeley.com)
  • A large area of skin must be stimulated to affect brainwaves, which leaves both auditory and photic stimulation as the most effective and easiest means of affecting brain activity. (wikipedia.org)
  • They produced the world's first electronic clinical photic stimulator - the Schneider Brain Wave Synchronizer. (wikipedia.org)
  • This "stroboscopic photo-stimulation produces "photic driving", the alpha type of brain electrical activity associated with an altered state in which people are susceptible to suggestion. (wikipedia.org)
  • Light
  • The influence of rhythmic sounds and drums to enter altered states of consciousness is used in different indigenous tribes (see Shamanic music), as well as optical stimulation produced by the flickering light of camp fires or pressing lightly on the eyeballs. (wikipedia.org)
  • A photic sneeze results from exposure to a bright light. (wikipedia.org)

  • BACKGROUND: The subthalamic nucleus (STN) is an efficient target for treating patients with Parkinson's disease as well as patients with obsessive-compulsive disorder (OCD) using high frequency stimulation (HFS). (mendeley.com)
  • Results
  • With the development of the EEG, Adrian and Matthews published their results showing that the alpha rhythm could be "driven" above and below the natural frequency with photic stimulation. (wikipedia.org)
  • electrical
  • These investigations are aimed at studying the influence of the electrical stimulation of the VIth nucleus (abducens nucleus) on responses of lateral geniculate cells in rabbits. (biomedsearch.com)
