Drs Michael Lemole and Rainier Gruesner speak with Keith about Congresswoman Giffords’ condition after being shot in Tucson, Arizona last Saturday. Also, from NPR more information about the bullet’s trajectory through her brain.

Giffords is still able to understand basic instructions to move her fingers and toes, neurosurgeon G. Michael Lemole, Jr. said. He said that shows that “not only are the centers in the brain working but they’re communicating with one another.”

Brain scans show no additional swelling in the brain. “No change is good,” Lemole told reporters. “Every day that goes by and we don’’t see an increase, we will be more optimistic.”

We have a little more information on the trajectory now. NPR producer Amy Walters asked if there had been damage to Giffords’ vision. “The track of the bullet is higher, away from the base of the skull, where those nerves enter and exit, so that’s a positive thing,” Lemole said.

But the injury may have affected her vision, he added, because the nerves that control and process vision run through several different areas of the brain.
