• Resumen

  • In 2014, Steven Laureys at the University of Liege in Belgium and his colleagues discovered that 13 people with minimal consciousness and two people in a vegetative state showed new signs of awareness when given mild electrical stimulation. The people in the trial received transcranial direct current stimulation (tDCS), which applies low-level electrical stimulation via electrodes on the scalp to make neurons more or less likely to fire. This was targeted once over an area of the brain involved in consciousness. Soon after, they showed signs of consciousness, including moving their eyes when instructed. Two people were even able to answer questions for 2 hours by moving their body, before drifting back into their previous state.
