Eine einzige Trainingseinheit kann zu einer Steigerung der neuronalen Aktivität in Gehirnnetzwerken führen, die dem Lernen und dem Gedächtnis zugrunde liegen

>Neuroscientists have documented ripples relevant to memory in mice and rats, but they had not confirmed the link in humans, mainly because electrodes need to be implanted in the brain to obtain recordings. Instead, researchers had theorized the ripples’ role in humans, based on studies in people that measured changes in oxygenated blood in the brain after exercise. This new study marks the first time researchers have been able to see the neurons in action in people following exercise, the authors report.

>The Iowa-led team recruited 14 patients at University of Iowa Health Care Medical Center, between 17 and 50 years of age, to participate. After a brief warmup, **participants rode a stationary bike for 20 minutes at a pace they could maintain for the duration**. Researchers recorded the participants’ brain activity before and after the cycling session using intracranial electroencephalography (iEEG), which utilizes implanted electrodes to measure neural activity in the brain.

>The recordings showed an increased rate of ripples originating in the hippocampus and connecting with cortical regions of the brain known to be involved in learning and memory performance.
