Fig. 1. Experimental design of HKA recording system. (A) Actual setup of house-keeping recording system with animal in distributional housing cage (left) and enlarged view of metal sipper tube in metal contact with metal lid (right). (B) Metal contact acts as a bridge to detect drinking behavior through the metal lid. (C) Type of characteristic behaviors which generate electrical conductance: grabbing, drinking and eating. (D) Type of characteristic behaviors which do not generate a conductance: hanging, crawling and sleeping.
