„Moment, hier war ich doch schon!“ – Wie das Gehirn Ortserinnerungen bildet

Tübinger Forscher aktivieren im Experiment vormals ruhende Gedächtniszellen Tübinger Neurowissenschaftlern ist es gelungen, ruhende Gedächtniszellen von Ratten zu aktivieren. Durch gezielte schwachelektrische Impulse konnten sie vormals inaktive Zellen im Hippocampus dazu bringen, den Ort der Impulsverabreichung wiederzuerkennen. Der Hippocampus ist … Continue reading

UCLA Scientists Discover Sleeping Brain Behaves as If It’s Remembering Something

UCLA researchers have for the first time measured the activity of a brain region known to be involved in learning, memory and Alzheimer’s disease during sleep. They discovered that this region, called the entorhinal cortex, behaves as if it’s remembering … Continue reading
