Provided is a conscious animal ultrasonic neural regulation device, including a pulse signal generation module, a transducer module and a fixing module. The pulse signal generation module is configured to generate a pulse signal with high energy. The ultrasonic transducer module is configured to convert the pulse signal into an ultrasound. The fixing module includes an upper fixing module and a lower fixing module. The upper fixing module is configured to fix the ultrasonic transducer module, and the lower fixing module is configured to be fixed on an animal neural regulation target point. The upper fixing module and the lower fixing module are connected by a connecting component. The conscious animal neural regulation device of the present disclosure can perform accurate ultrasonic stimulation on a cerebral cortex and subcortex of the animal, thereby exploring and verifying the stimulation effect of the ultrasound on the animal, which is easy in operation and convenient in use.
