Recent advances in brain imaging have revolutionized our understanding of neural circuits at the level of proteins, cells, and network interactions. In particular, optical techniques combined with novel probes to measure neural activity enable an unprecedented window into brain function. Additionally, new methods are being developed to image the brain in freely moving animals to investigate function during behavior. This symposia will focus on the latest optical methods applied to imaging the brain in vivo with future implications for research in neurological disorders and basic neuroscience. Topics include fast volumetric imaging such as lightsheet, multifocus methods, multiphoton microscopy, spectroscopic imaging, fiber-based imaging, optical probes, and laser sources.
2020 marks the 60th anniversary of the invention of the laser. The laser is doubtlessly the most important tool in optics, and many of the most exciting scientific results reported at CLEO have always been related to the understanding, development, characterization, and application of lasers in a vastly growing number of fields. The importance of the laser has also of course been recognized at the very highest scientific level with the award of many Nobel Prizes, including the most recent Nobel Prize in Physics in 2018.
At a time when optics and photonics industries thrive and many young scientists enter the field, it is important to trace a line from the early days of invention in the 1960s to the current status of the laser, with particular emphasis on showing that many of the basic concepts of laser operation are still subjects of active and important research. It is often the case that revisiting basic concepts in light of new technologies can open new perspectives, and the 60th anniversary of the invention of the laser is an excellent occasion to stimulate renewed interest into what is the most fundamental optical component of photonics.
