News Articles: brain

Researchers integrated four organoids that represent the four components of the human sensory pathway, along which pain signals are conveyed to the brain. Stimulation of the sensory organoid (top) by substances, such as capsaicin, triggers neuronal activity that is then transmitted throughout the rest of the organoids.
