Fig. 6. (A) A multimodal microprobe with optical and electrical measurements of neural activities. The multimodal probe consisted of a dual-core optical fiber, which excited fluorescent indicators and collected emitted signals, and an electrical wire to record electrical activities in neurons. This figure in [

(B) A schematic of an optetrode, which consisted of a single optical fiber with 200 µm core diameters for optogenetic stimulations and a tetrode to record neural activities and changes when the optical stimulation occurs. The re-use of this figure published in [
124] was approved by Nature Publishing Group (Springer Nature).
