| Outline of Final Research Achievements |
We developed a whole brain recording system which can simultaneously record neuronal activity and EEG over several brain regions. Specifically, using 3D printing technology, we tested the performance of the developed system in a rapid prototyping fashion. Consequently, we made an independently movable microdrive which can access not only deep brain areas but also superficial of the cortex. To evaluate the performance of the system, we recorded place-cell activity while the animal paused. Results suggested that the sequential activation of place-cells are replayed about 10 times faster than that during running. We conclude that our developed system can record both neuronal activity and EEG over several brain regions.
