3-D ‘Heat Map’ Animation Shows How Seizures Spread in Brains of Patients with Epilepsy
For 29 years, from the time she was 12, Rashetta Higgins had been wracked by epileptic seizures – as many as 10 a week – in her sleep, at school and at work. She lost four jobs over 10 years. One seizure brought her down as she was climbing concrete stairs, leaving a bloody scene and a bad gash near her eye.
A seizure struck in 2005 while she was waiting at the curb for a bus. “I fell down right when the bus was pulling up,” she says. “My friend grabbed me just in time. I fell a lot. I’ve had concussions. I’ve gone unconscious. It has put a lot of wear and tear on my body.”

Study identifies the key genes in the brain involved in encoding memories
UT Southwestern scientists have identified key genes involved in brain waves that are pivotal for encoding memories. The findings, published online this week in
Nature Neuroscience, could eventually be used to develop novel therapies for people with memory loss disorders such as Alzheimer’s disease and other forms of dementia.
Making a memory involves groups of brain cells firing cooperatively at various frequencies, a phenomenon known as neural oscillations. However, explain study leaders Bradley C. Lega, M.D., associate professor of neurological surgery, neurology, and psychiatry, and Genevieve Konopka, Ph.D., associate professor of neuroscience, the genetic basis of this process is not clear.
