Recruited as research scientist at Massachusetts Institute of Technology
ENP graduate Nima Dehghani has explored the presence of self-organized critical states in cat, monkey and human brains. He evaluated whether or not such states are present during wakefulness, slow-wave sleep, and REM sleep. After analyzing recordings from high-density electrode arrays and local field potentials, he did not find clear evidence for power-law scaling and self-organized critical states.
