In this episode Dr. Jonathan Nassi, Senior Director of Translational Science at Inscopix Inc, joins Science Decoded to discuss his recent paper on brain imaging in non-human primates. The goal of Dr. Nassi's study is to bridge a gap in brain imaging. Brain imaging traditionally has been done at the micro scale, or sub-cellular level, and at the macro scale, which gives a zoomed-out view of the brain. To observe the brain at a scale between these two extremes, known as the meso scale, Dr. Nassi and Inscopix developed an incredibly small microscope that can be placed on primates while still allowing the individual to move freely. The team used this microscope technology to observe non-human primates' brains during motor tasks and during periods of external stimuli.
