a cell fusion generator (LF101; NepaGene, Japan). Then, oocytes were washed several times and incubated for 30 min in TLH-BSA, after which they were examined for fusion. Reconstructed oocytes were activated by applying two DC pulses of 120 V/ mm for 60 sec in a 280 mM mannitol solution with 100 M CaCl 2 and 50 M MgCl2. For PA, the MII oocytes having polar bodies were electrically activated using a... -

filter and 20 Hz low-pass filter respectively, since the rd1 retina is known to have the oscillatory local field potential with ∼10 Hz rhythm [9,26,27]. Electrical stimulation Using a stimulus generator (STG 1004, Multichannel sys- tems GmbH, Germany), current pulse trains were delivered to the retinal preparation via one of the 60 channels (mostly channel 44 in the middle of the MEA). The... of the pulse. For intensities (or duration) modulation, duration (or amplitude) of the pulse was fixed to 500 μs (30 μA), changing the intensities (or duration) from 2 to 60 μA (60 to 1000 μs). RGCs were classified as response-positive when PSTH showed multiple (3∼4) peaks within 400 ms post stimulus and the number of spikes was at least 30% more than that for the immediate pre-stimulus 400 ms period. RGC responses were well modulated both with anodic and cathodic phase-1st biphasic pulses.... -

one RGC can be recorded in one channel of the MEA, a procedure to sort multi-unit activities to single-unit activity was also carried out. Electrical stimulation Charge-balanced biphasic current pulse trains were gen- erated (anodic pulse first, no temporal separation between two phases). Pulse amplitude and duration were fixed at 30 μA and 500 μs, respectively, which can reliably evoke RG... RGC firing rates while increasing the pulse frequency from 1 to 10 pulses per second (or Hz) to deduce the optimal pulse frequency range for modulation of RGC response strength. RGC response strength monotonically and linearly increased within the stimulation frequency of 1∼9 Hz. The results suggest that the evoked neural activities of RGCs in degenerated retina can be reliably controlled by pulse frequency modulation, and may be used as a stimulation strategy for visual neural prosthesis. -

본 연구는 AFM 을 이용하여 nano scale 의 Lithography 를 구현하는 것이다. 외부의 pulse generator 를 통하여 전류를 통전 시키는 방법을 수정함으로써, 일정 습도를 유지한 상태의 AFM 내부에서 Si-wafer 의 표면과 Tip의 사이에 전원을 인가하고 pulse generator 에서 임의로 pulse 폭의 변화를 준다. Si-wafer 표면에서 물 분자가 Tip과 wafer 사이의 직접적인 전류의 이동조절로 인해 전기 화학적 반응을 적절히 제한하여 산화물을 생성시키는 방법이다. 이렇게 생성된 산화물은 불산 처리를 통하여 산화물을 식각시켜 미세...
