    摘要： In vivo multi-channel recording is a powerful tool in exploring the real time neural activity associated with specific behavioral outputs. A prominent strength of this technique is that a large number of neurons can be, in theory, simultaneously recorded such that the activity of a small neural circuitry can be formulated and assessed. The present application provides for a new, adjustable multi-electrode system (AMES). Electrodes in this AMES, once installed into the brain, can be individually adjusted such that each electrode can be independently protruded until it reaches an optimal position to acquire neuronal signals. Thus, every electrode within the multi-electrode system is able to acquire valid signals. This adjustable multi-electrode system substantially improves the efficacy of signal acquisition and offers an unprecedented power for in vivo recordings.

    摘要： A driver circuit drives a pulse width modulation (PWM) controller. The driver circuit includes an enabling circuit, a power supply input control circuit, a stabilizing circuit, and a discharge circuit. The stabilizing circuit is electrically connected to the PWM controller. The power supply input control circuit is electrically connected between the enabling circuit and the stabilizing circuit. The discharge circuit is electrically connected between the stabilizing circuit and the ground. In response to the driver circuit working in normal operation, the enabling circuit enables the power supply input control circuit to output a working voltage to the stabilizing circuit, and in response to the process of the driver circuit restarting, the enabling circuit enables the power supply input to stop outputting power supply to the stabilizing circuit. The discharge circuit leads a residual voltage of the stabilizing circuit to the ground, during the process of the driver circuit being restarted.
