抄録

We have developed a multielectrode array recording system for single-neurite-firing measurement using an artificially constructed neuronal network on a chip, which has a 10 um diameter array with electrodes spaced at 50 μm, for noninvasive 64-channel 100 kHz multirecording and the stimulation of a plurality of neuntes extending from a single neuron. To improve the signal/noise ratio, the ground plane was set on the multi-electrode-array plane and platinum black was set on each of the 10 μm electrodes. Using this system, we performed a multisite recording of neurites of a single neuron of a rat hippocampal network in cases of both spontaneous firing and evoked responses to electrical stimulations, and estimated the velocity of action potential propagation among neurites of a single neuron from six recording sites. This demonstrated the potential use of our low-noise chip and our high-speed measurement system for the analysis of neuronal network activities at the single-neuron level.
