Doctors say Deputy Nick Tullier is doing "remarkably well" considering the severity of his injury.
When he was shot on July 17 during the Baton Rouge ambush shooting, bullet and bone fragments damaged the left side of his brain.
Tullier wasn't expected to survive the first 24 hours after the shooting, but TIRR Memorial Hermann doctors say thanks to the medical care in Baton Rouge, he hung on.
Tullier was flown to TIRR Memorial Hermann in November and has participated in daily intensive physical therapy. Doctors say he's conscious.
In a news conference Thursday, a panel of medical professionals said Tullier is aware of what's around him, he can see, he knows he's in a hospital in Houston and he knows his family is by his side. However, he cannot speak. Doctors say his mind and body aren't always in sync. He still faces a lot of challenges, including suffering from paralysis of the limbs. While his mind may want to move, his body cannot.
Tullier is currently receiving physical therapy treatment at the hospital and his family says he knows he is in Texas.
James Tullier, Nick's father, said, Nick's got a real long way to go...to us, yes, Nick's a miracle."
A former Marine is accused in the attack on the Baton Rouge officers. Three law enforcement officers were killed in the attack.
