Scientific illustrations for an article about Cocaine Astrocytes (Lactate release from astrocytes to neurons contributes to cocaine memory formation) by Benjamin Boury-Jamot, Olivier Halfon, Pierre J. Magistretti and Benjamin Boutrel published in the journal Bioessays n°38. Many thanks to Benjamin Boutrel for his patience and help with the figures. I enjoyed listening to every second of his explanations about what it is I was illustrating! [CHUV 2016]
