Previously unknown neural mechanism of habit formation identified

There is little doubt that dopamine transmission in the brain plays a role in habit formation. However, two central questions that remain are which of the different dopamine projection pathways in the brain are critical, and how pathway-specific dopamine signaling changes over the course of habit development. Researchers from the Netherlands institute of Neuroscience (NIN) now show findings that challenge the status quo in the field of behavioral neuroscience.
