New paper out in J Neuroscience: Amplification and Suppression of Distinct Brain-wide Activity Patterns by Catecholamines

By Ruud van den Brink & Tobias Donner. A class of neurotransmitters known as catecholamines (norepinephrine and dopamine) play an important modulatory role in brain function. These catecholamines are synthesised by neurons clustered in small nuclei of the brainstem, which
