would also observe the behavioral outcome, Mohanty said.
Optogenetic stimulation avoids damage to living tissue by using light to stimulate neurons instead of electric pulses used in past research. Mohanty's method of using low-energy near-infrared light also enables more precision and a deeper focus than the blue or green light beams often used in optogenetic stimulation, the paper said.
Using fiber optics to deliver the two-photon optogenetic beam is another advance. Previous methods required bulky microscopes or complex scanning beams. Mohanty's group is collaborating with UT Arlington Department of Psychology assistant professor Linda Perrotti to apply this technology in living animals.
"Dr. Mohanty's innovations continue to be recognized because of the great potential they hold," said Pamela Jansma, dean of the UT Arlington College of Science. "Hopefully, his work will one day provide researchers in other fields the tools they need to examine how the human body works and why normal processes sometimes fail."
Mohanty's co-authors on the research were members of his lab, Kamal Dhakal, Ling Gu and Bryan Black.
The paper in Optics Letters is called "Fiber-optic two-photon optogenetic stimulation" and it is available online here.
