Research yielding insights into brain’s signaling network

WEST LAFAYETTE, Ind. – Researchers have taken an important step toward deciphering the brain’s complex neuroelectric communication system that could underlie sleep disorders and conditions such as Alzheimer’s, epilepsy and schizophrenia. The complex communication network connects groups of neurons that can be identified and studied by imaging the brain while a person rests using functional magnetic resonance imaging. Because the brain’s resting state is not biased by any particular task, the approach provides a way to study its “intrinsic functional organization,” said Zhongming Liu, an assistant professor of biomedical engineering and electrical and computer engineering at Purdue University. “The rationale behind this is that when the brain is not doing anything it is not literally quiet but remains very active, providing many kinds of signals,” he said. Purdue researchers are…
