"Pocket Monsters," an action-packed cartoon taken off the air in December after a visually intense episode sent at least 700 viewers to hospitals, many in convulsions, is ready for a comeback.
TV Tokyo's decision to bring back a toned-down version of the series April 16 follows investigations by the network and the National Association of Commercial Broadcasters.
The Dec. 6 episode featured a few seconds of rhythmic strobelike flashes of blue, red and white, each about one-thirtieth of a second long.
Reactions to it included nausea, hyperventilation, convulsions and loss of consciousness.
Researchers say the flashing lights might have simply overexcited some children. In other cases, however, they might have caused convulsions by disrupting the natural pacemakers that regulate normal brain patterns.
