Tenim un sisè sentit, el de l’orientació? Un estudi controvertit

Al llibre “Life on the edge”  hi ha un capítol sencer dedicat als efectes quàntics vinculats al fet que hi ha ocells que fan llargues migracions en direcció nord-sud. L’explicació sembla poder-se trobar en efectes quàntics en molècules del cap dels ocells. He vist ara, però, que s’ha fet un estudi sobre el tema, amb persones: The Guardian publica l’article The sixth sense: can humans detect the Earth’s magnetic field? on comenta un article de la revista eNeuro.

scientists at the California Institute of Technology report evidence that men and women’s brains respond to changes in magnetic fields and these alternations could allow them to differentiate north from south and navigate without compasses.

L’autor de l’article creu que les molècules responsables de l’efecte quàntic no són ben bé les mateixes que d’altres autors han postular. En tot cas, es tracta d’un assumpte molt interessant.

M’ha semblat rellevant l’aportació lingüística sobre el llenguate europeu egocèntric i els llenguatges sudasiàtics/oceànics:

For example, Kirschvink points to studies of Asian and Australian people who speak languages that are fundamentally different to European languages. These differences could influence our abilities to respond to weak signals from our “internal compasses”.

“These people have no words for front or back or to your right. Instead they talk about looking in a direction to your north or turning to your east. These are languages of geographic reference and they are still spoken by aboriginal people.”

Such languages would be better suited to responding to internal compasses, added Kirschvink, and would help men and women to think in ways that keep them tuned to their innate abilities to navigate. “European languages, which have an egocentric reference frame, may now be blocking our ability to use our brains in this way,” he added.

Senzillament, apassionant.
