"Cumulus exists to reduce uncertainty in neuroscience. For too long, CNS drug development has been hampered by invisible signals, placebo effects, heterogeneity in symptoms and in patients, and overly subjective endpoints. And even though technology and objective biomarkers have advanced rapidly, this area is still underdeveloped. Our aim is to change that — to create parity of care for people living with neuropsychiatric conditions. Objective measurement of brain function is a challenge worth taking head-on."
