Protocol for behavioral tests using chemogenetically manipulated mice.

Behavioral analyses using mice chemogenetically manipulated by designer receptors exclusively activated by designer drugs (DREADDs) are powerful tools to elucidate neural functions. Here, we describe the detailed protocols for stereotaxic surgery, adeno-associated virus (AAV)-mediated introduction to Gq-DREADDs in mice, and for behavioral testing and analyses related to anxiety, risk assessment, and burying behaviors. A series of these tests are useful in evaluating animal anxiety and their defensive response patterns to potential threats. For complete details on the use and execution of this protocol, please refer to Horii-Hayashi et al. (2021).
