In light of Baker's reporting, Stanford University opened its own internal inquiry into the matter. A panel of scientists concluded that Tessier-Lavigne's work contained image manipulations in 2001, the early 2010s, 2015-2016, and 2021.

But the panel dismissed any allegations of fraud or misconduct on the part of Tessier-Lavigne himself. Instead, they conclude that the "unusual frequency of manipulation of research data" in the neuroscientist's lab "suggests that there may have been opportunities to improve laboratory oversight and management".
