"Moment, hier war ich doch schon!" - Wie das Gehirn Ortserinnerungen bildet

Tübinger Forscher aktivieren im Experiment vormals ruhende Gedächtniszellen

(PresseBox) (Tübingen, )
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 bei Nagetieren wie auch dem Menschen für das Gedächtnis zuständig. Die Studie des Forscherteams am Werner Reichardt Centrum für Integrative Neurowissenschaften (CIN) der Universität Tübingen gibt daher Hinweise darauf, wie in unserem Gehirn Erinnerungen gebildet werden. Die Ergebnisse wurden nun im Fachmagazin Current Biology veröffentlicht.

Das Gedächtnis ist eine der wichtigsten Funktionen unseres Gehirns. Mit seiner Hilfe können wir nicht nur unseren Enkelkindern eines Tages allerlei Unterhaltsames aus nlxlfho Bpwemj ypeqynmi.
