The earliest human graphic productions, consisting of abstract patterns engraved on a variety of media, date to the Lower and Middle Palaeolithic. They are associated with anatomically modern and archaic hominins. The nature and significance of these engravings are still under question. To address this issue, we used functional magnetic resonance imaging to compare brain activations triggered by the perception of engraved patterns dating between 540 000 and 30 000 years before the present with those elicited by the perception of scenes, objects, symbol-like characters and written words. The perception of the engravings bilaterally activated regions along the ventral route in a pattern similar to that activated by the perception of objects, suggesting that these graphic productions are processed as organized visual representations in the brain. Moreover, the perception of the engravings led to a leftward activation of the visual word form area. These results support the hypothesis that these engravings have the visual properties of meaningful representations in present-day humans, and could have served such purpose in early modern humans and archaic hominins.<\/p>\n

Bien avant les peintures de la grotte de Lascaux, les premiers humains ont inscrit des motifs abstraits sur des pierres, des coquillages ou des coquilles d\u2019\u0153ufs, les plus anciens datant de 540 000 ans. Pour les arch\u00e9ologues qui ont d\u00e9couvert ces trac\u00e9s pr\u00e9historiques la question est de savoir s\u2019ils \u00e9taient le fruit du hasard, d\u2019une volont\u00e9 d\u2019imiter la nature ou dot\u00e9s d\u2019une signification.<\/p>\n

Une collaboration in\u00e9dite entre des arch\u00e9ologues (du laboratoire PACEA<\/strong> : CNRS \/ Universit\u00e9 de Bordeaux \/ Minist\u00e8re de la culture) et des chercheurs en neuroimagerie cognitive de l\u2019IMN<\/strong> (CNRS \/ universit\u00e9 de Bordeaux \/ CEA) offre pour la premi\u00e8re fois des \u00e9l\u00e9ments de r\u00e9ponse \u00e0 cette question. Ces motifs abstraits pr\u00e9historiques sont analys\u00e9s par les m\u00eames zones du cerveau que celles qui reconnaissent les objets. Ils activent \u00e9galement une r\u00e9gion de l\u2019h\u00e9misph\u00e8re gauche bien connue dans le traitement du langage \u00e9crit. Les r\u00e9sultats de cette collaboration interdisciplinaire renforcent l\u2019hypoth\u00e8se que nos anc\u00eatres ont tr\u00e8s t\u00f4t attribu\u00e9 une signification \u00e0 leurs trac\u00e9s, peut-\u00eatre m\u00eame symbolique. Ils sont publi\u00e9s dans Royal Society Open Science<\/em> le 3 juillet 2019.<\/p>\n
