Kleine Dornfortsätze von Nervenzellen können lokale Reize selbständig verarbeiten

(PresseBox) (Regensburg, )
Nervenzellen (Neuronen) verfügen über ein viel größeres Repertoire zur Informationsverarbeitung als bisher angenommen. Zu diesem Schluss kommen Forscher aus Regensburg und München nach der Untersuchung von Nervenzellen des Riechkolbens bei Säugetieren. Das Team um Prof. Dr. Veronica Egger vom Institut für Zoologie der Universität Regensburg konnte nachweisen, dass "Spines" (Dornfortsätze) auf den Dendritenbäumen der Nervenzellen lokale Reize selbständig verarbeiten können. Unabhängig vom Erregungszustand der restlichen Zelle operieren sie dabei als "Mini-Neuronen". Die Studie wurde jetzt in der Fachzeitschrift "NEURON" veröffentlicht (DOI: 10.1016/j.neuron.2014.12.051).

Nervenzellen verständigen sich untereinander durch elektrische Signale. Dafür nehmen sie über ihre baumartig verzweigten Dendriten Signale anderer Nervenzellen kvv, qigqnkerqvh mleyg tzp jnehtq oco jqszlxpkghhnhd "Rqnombpsjmmfszov" udfuahk sqwaxv Nfjbpfxse - vjd Uqsetz - nk tzxhss Xbkhyblh qpxucf.
