A deeper dive with photons
Abstract/Contents
- Abstract
- Subtitle-- Recent breakthroughs in optical-based imaging in nonhuman primates promise to fundamentally advance our understanding of brain function and accelerate the development of next-generation brain-computer interfaces.Summary-- Two new studies demonstrate complementary approaches for imaging the activity patterns of large populations of neurons in nonhuman primates (NHPs).-- Bollimunta*, Santacruz* & colleagues used a head-mounted one-photon miniature microscope to image the activity of neurons deep in the motor cortex of a behaving macaque, and demonstrated the ability to perform offline decoding of the animal’s motor behavior using the same neurons tracked over weeks.-- Trautmann*, O’Shea*, Sun* & colleagues used two-photon microscopy to image the activity of neurons, also in the motor cortex, and show that it is possible to access deep cortical neurons by imaging their apical dendrites near the surface, allowing them to perform online, closed-loop decoding of the behaving macaque’s motor behavior sufficient to drive an optical brain-computer interface (BCI).-- Together, these studies pave the way for new experiments to understand how populations of neurons underlie behavior, and how new BCI technologies can treat neurological injury and disease.
