Femtosecond Lasers: Innovation in Neuroscience

NeuroscienceBack in 2013, the Obama Administration took the initiative in innovating technologies to treat various neurological ailments. Scientists made further explorations into those conditions when the World Health Organization showed that psychiatric disease was a leading source of disability worldwide — and that stays true until now.

What is Optogenetics?

I-Han Chou, senior editor of Nature says that optogenetics is the ability to manipulate individual neuronal circuits. The biological technique modifies your perception of how neurons usually work and relate to various aspects of personality and behavior. Here, scientists use light and genetics to modify brain cells and “switch” them on and off on command.

The technique works only on animals, specifically on rats. Scientists are looking for ways for optogenetics to work on humans. It might be useful for the restoration of brain function.

Femtosecond Lasers: Advances in Neuroscience

Optogenetics uses light-sensitive opsins, which are switchable channels whose on and off state relies on irradiation with light of an appropriate wavelength. Scientists previously used filtered lamps and LEDs. They began using lasers because these provide spatial selectivity and high brightness. Femtosecond lasers have the capability to excite multiphoton processes.

Industrial lasers have a huge influence on the world of science, as the tools minimize downtime in between experimentation to the publication of results. How do they do it? The latest designs now have higher reliability because manufacturing companies implement Highly Accelerated Stress Screening (HASS) to make sure that these products generate constant results as they run 24/7.

The Future of Optogenetics

Karl Deisseroth, M.D., Ph.D. from Stanford University shares that while the continual release of innovations allows for better and more precise altering of naturally occurring brain patterns, there are hopes of a more powerful system involving a union of fields. This capability includes combining imaging and the collection of light, with playing in or providing light.
