Abstract

DESCRIPTION provided by applicant Improving our understanding of the functional circuitry of the brain has important and manifold implications for our understanding of mental health as well as fields like consciousness and computing In the last decade optical techniques have arisen that allow both recording and control of targeted neurons for brain mapping and many of the best of these techniques employ multiphoton microscopes with spatial light modulator SLM technology and complex algorithms to shape the light and analyze increasingly large neural microcircuits in three dimensions D SLMs can arbitrarily shape the wavefront of light to create multiple independently targeted beams in D to control groups of neurons with the maximum number of studied neurons being limited primarily by the laser power on the SLM Because the SLM can mimic nearly any optical element these versatile tools also provide additional capabilities when incorporated into microscopes such as adaptive aberration correction and remote focusing Despite the potential for SLMs to revolutionize the microscopes used in neuroscience their adoption remains limited by the difficulty in incorporating the SLM into the expensive multiphoton microscope platforms used by investigators and by the complexity of integrating SLM control into the microscopy software In this Phase II effort Boulder Nonlinear Systems BNS and Dr Darcy Peterka and the Yuste laboratory at Columbia University will address this barrier by developing a user friendly bolt on SLM module for existing multiphoton microscopes along with full software integration of the SLM into both open source and commercial microscopy software This work will leverage knowledge gained during the Phase I development of the Pocketscope a portable and low cost SLM microscope for simple in vitro neuroscience studies and integrate close feedback from a range of industry partners and leaders in neuroscience As part of this work BNS will also improve the speed power handling and reliability of the SLMs and utilize their strategic commercial partner Meadowlark Optics to bring down SLM cost and improve software integration Successful completion of this project will result in the new SLM based microscope module platform indpendent software integration and improved SLM joining the Phase I Pocketscope to provide a suite of powerful tools each with their own impact and commercial niche capable of transforming the optical exploration of neural networks PUBLIC HEALTH RELEVANCE Improving our understanding of the functional circuitry of the brain has important and manifold implications for our understanding of mental health as well as fields like consciousness and computing In the last decade optical techniques have arisen that allow both recording and control of targeted neurons for brain mapping and many of the best of these techniques employ multiphoton microscopes with spatial light modulator SLM technology and complex algorithms to shape the light and analyze increasingly large neural microcircuits in three dimensions This project seeks to improve the adoption and dissemination of this powerful technique through close collaborations with industry and the neuroscience community to develop a user friendly add on SLM module and software for existing multiphoton microscopes
