Enhanced Microscopic Technique Offers Clearer Insight into Neuron Networks for Researchers
In a groundbreaking study, a team of MIT engineers and neuroscientists developed an innovative microscopy system, called multiline orthogonal scanning temporal focusing (mosTF), to image the living brain at high speeds and exceptional clarity. This system outperforms traditional two-photon microscopy in several aspects, making it a game-changer in studying neural plasticity.
Two-photon microscopy is widely recognized for its ability to provide high-resolution images deep within tissue, albeit at a relatively slower pace. The new mosTF system, however, offers significantly faster volumetric imaging, making it more suitable for capturing dynamic processes in real-time.
The authors of the study, including Elly Nedivi and Yi Xue, explain that mosTF microscopy works by scanning brain tissue with lines of light in perpendicular directions. This scanning process emits photons from brain cells engineered to fluoresce when stimulated, resulting in cleaner and sharper images compared to traditional two-photon systems.
So, what sets mosTF apart? The system is engineered to manage scattering, a common issue in brain tissue that can make images fuzzy. Unlike other systems that merely discard scattered photons, mosTF employs an algorithmic process to reassign scattered photons back to their origin. This allows the system to produce stronger signals, thereby resolving smaller and fainter features of stimulated neurons effectively.
In the study, mosTF was pitted against a point-by-point scope and a line-scanning temporal focusing microscope. Results showed that mosTF produced images with a four-fold better signal-to-background ratio than a two-photon system, enabling it to unravel the tiny details of neural processes in complex environments like a live mouse brain.
The collaboration between the So and Nedivi labs will continue to advance the technology, aiming to develop even more efficient microscopes for studying plasticity with improved speed and efficiency. This groundbreaking work is a significant leap forward in live brain imaging, offering exciting possibilities to deepen our understanding of the neural plasticity underlying learning and memory processes.
