Implantable silicon neural probes with nanophotonic phased arrays for single-lobe beam steering

Autor: Chen, Fu-Der, Sharma, Ankita, Xue, Tianyuan, Jung, Youngho, Govdeli, Alperen, Mak, Jason C. C., Chameh, Homeira Moradi, Movahed, Mandana, Brunk, Michael G. K., Luo, Xianshu, Chua, Hongyao, Lo, Patrick Guo-Qiang, Valiante, Taufik A, Sacher, Wesley D., Poon, Joyce K. S.

In brain activity mapping experiments using optogenetics, patterned illumination is crucial for deterministic and localized stimulation of neurons. However, due to optical scattering in brain tissue, light-emitting implantable devices are needed to b

Node-Centric Graph Learning from Data for Brain State Identification

Autor: Ghoroghchian, Nafiseh, Groppe, David M., Genov, Roman, Valiante, Taufik A., Draper, Stark C.

Publikováno v: IEEE Transactions on Signal and Information Processing over Networks, 6, 120-132 (2020)

Data-driven graph learning models a network by determining the strength of connections between its nodes. The data refers to a graph signal which associates a value with each graph node. Existing graph learning methods either use simplified models fo
