Ganzfeld effect

The Ganzfeld (from the Ger­man, mean­ing “full field”) effect describes the state of sen­so­ry depri­va­tion achieved by flood­ing one of the sens­es with a con­stant uni­form sig­nal. Once the con­stant sig­nal floods the par­tic­u­lar sense, the brain stops reg­is­ter­ing the dif­fer­en­ti­a­tion and the result is an absolute depri­va­tion of that par­tic­u­lar sense. Used for med­i­ta­tion, para­psy­chol­o­gy. [google]
