Formula 1 driver Jules Bianchi is no longer in an artificial coma and is breathing unaided, his parents have said in a statement.
The Marussia driver, 25, was seriously injured when he crashed in wet conditions into a recovery vehicle at the Japanese Grand Prix on 5 October.
The Frenchman has been flown from hospital in Yokkaichi to intensive care in Nice, where he arrived earlier.
However his condition is still "critical" and he remains unconscious.
"Almost seven weeks after Jules' accident at Suzuka Circuit, and following a challenging period of neurological intensive care, we are able to announce Jules has made an important step," his parents Philippe and Christine said in the statement.
"His treatment now enters a new phase concerned with the improvement of his brain function.
"Although the situation continues to be serious, and may remain so, it was decided that Jules was sufficiently stable to be repatriated to his native France."
Bianchi suffered a diffuse axonal injury when he crashed into a recovery vehicle at Suzuka.
His car collided with a tractor vehicle that was recovering Adrian Sutil's Sauber, which had crashed on the previous lap.
His family praised the "outstanding care" he received following the accident from doctors at the Mie General Medical Centre in Yokkaichi, adding they owed "an enormous debt of gratitude".
"We are thankful the next phase of Jules' treatment can continue close to home, where he can be surrounded and supported by his wider family and friends," they said.
