The Dons are in danger of being relegated for the first time ever as they sit a point behind Dunfermline Athletic (but with a game in hand) and Brown says the situation the club finds itself in is all his fault.
"I am shouldering full responsibility for where we are now," he said.
"I pick the team, I've signed a lot of the players and I'm the one who prepares them for the games. I'm not going to start ducking out and blaming anyone else for us going to the bottom of the league. It would be wrong to pass the buck to anyone else.
"It's not the fault of the players, the board or anyone else at Pittodrie. It's all down to me.
"The manager is the one who is the leader of the team and I've got to be able to look people in the eye and admit I haven't done as well at Aberdeen so far as I would have liked.
"I took the credit when things went well for me during my managerial career, so I have to take the blame when results haven't gone as I would like."
