As many labs have established, Dr. Zaghloul\u2019s team knew that our episodic memories are controlled by neurons in at least two different parts of the brain, but they did not know exactly how the cells worked together to retrieve memories. Based on a growing of body of evidence, they suspected that the short, high frequency electrical waves seen in ripples may somehow be involved. For instance, two earlier patient studies suggested that ripples may be important for solidifying memories during sleep.<\/p>\n

A sound, a smell, a word can all flood our minds with memories of past experiences. In a study of epilepsy patients, researchers at the National Institutes of Health found that split seconds before we recall these events tiny electrical waves, called ripples, may flow through key parts of our brains that help store our memories, setting the stage for successful retrieval.<\/p>\n

\u201cWe showed for the first time that ripples<\/a> may be the neural substrates through which the human brain<\/a> successfully recalls memories,\u201d said Kareem Zaghloul, M.D., Ph.D., a neurosurgeon-researcher at the NIH\u2019s National Institute of Neurological Disorders and Stroke (NINDS) and senior author of the study published in Science<\/i>. \u201cThese results help us understand how the brain<\/a> processes the details of our past waking experiences or episodic memories.\u201d<\/p>\n

The study was led by Alex P. Vaz, B.S., an M.D., Ph.D. student at Duke University, Durham, North Carolina, who was completing his dissertation work with Dr. Zaghloul. For years, Dr. Zaghloul\u2019s team has been using grids of surgically implanted electrodes to record the electrical brain activity of drug resistant epilepsy patients<\/a> enrolled in a trial at the NIH\u2019s Clinical Center. The recordings have helped identify the source of a patient\u2019s epileptic seizures<\/a> as well as provide an opportunity to study how the brain encodes memories.<\/p>\n
