Stadtplan im Kopf

Zellen im Gehirn bauen Gittermuster, um die Umwelt zu kartieren

(PresseBox) (Berlin, )
Tiere und Menschen orientieren sich mit Hilfe eines inneren Navigationssystems. Bei Säugetieren sind zwei Hirnteile maßgeblich am Aufbau von solchen räumlichen Repräsentationen beteiligt: Der Hippocampus und die entorhinale Hirnrinde. Diese Hirnstrukturen speichern Sinneseindrücke und repräsentieren sie in Form einer kognitiven Karte, einer mentalen Darstellung der räumlichen Struktur der Umwelt. Die Repräsentation des Raumes in der entorhinalen Hirnrinde ist besonders bemerkenswert: Dort finden sich sogenannte Gitterzellen (Nervenzellen, die in räumlichen Gittermustern aktiv sind), wenn sich Tiere fortbewegen. Man nimmt an, dass das Gehirn diese räumlichen Aktivitätsmuster ähnlich einsetzt, wie wir die Gitterlinien auf Stadtplänen oder Landkarten nutzen, um Orte zu lokalisieren cqzm pa Eswwxrmbifxc dv omgfpl.
