Here, na\u00efve ants align nest-directed views using the earth\u2019s magnetic field as a compass reference. Neuronal plasticity was mapped in two visual pathways to higher brain centers during this transition. Both their first exposure to light, and the performance of learning walks lead to distinct changes in synaptic circuits along both visual pathways, reflecting calibration and memory formation in the ants\u2019 visual compass systems.<\/p>\n<p>&nbsp;<\/p>\n<p>For further info, please read the paper Grob et al. 2019.<\/p>\n<p>Robin Grob, Pauline N.
