A multinational research team has now been able to increase their understanding of species-specific variations in the architecture of cortical neurons thanks to high-resolution microscopy.

Researchers from the Developmental Neurobiology research group at Ruhr-Universität Bochum, led by Professor Petra Wahle, have demonstrated that primates and non-primates differ in an important aspect of their architecture: the origin of the axon, which is the process responsible for the transmission of electrical signals known as action potentials. The results were recently published in the journal eLife.
