Lensless Cameras May Offer Detailed Imaging of Neural Circuitry Jul 19, 2018 — Understanding brain function at the scale of individual neurons could open the door for advanced understanding of animal and human behavior and the mechanisms of neurological disorders such as Alzheimer’s. But the size scale of neurons and their extremely large numbers create an extreme imaging challenge. Calcium imaging enables optical monitoring of the action potential of individual neurons, resulting in maps of neural circuitry in living brains. To achieve this, calcium-sensitive
