Neurosurgeon Dr. Michael Lemole of Tucson's University Medical Center says Giffords is still responding to doctors and her condition is stable. Her brain remains swollen, but the pressure hasn't increased. He says they're much more optimistic.
Of those injured in the deadly shooting Saturday in Tucson, eight are still hospitalized. Giffords is in critical condition. Five others are in serious condition, and two in good condition.
A federal judge, a congressional aide and a 9-year-old girl, Christina Taylor Green, were among the six people killed, while Giffords and 13 others were injured.
