Elucidating the functional structure of deep brain regions

Tatsuya Oikawa, Toshimitsu Hara, Kento Nomura, along with Associate Professor Kowa Koida of the Department of Computer Science and Engineering, Toyohashi University of Technology, have developed a technology capable of deploying very small "marks" in regions of the brain where activity is been recorded. These marks are created by passing a micro current through tungsten electrodes inserted in the brain to record brain activity. These marks do not damage brain tissue and can remain safely inside the brain of a living organism. This technology enables a high-resolution visualization of the brain-wide distribution of neurons with particular functional characteristics. The results of this research were published on September 11, 2023, in the online version of eNeuro.
