Rangers remain nine points clear at the top despite being on the end of one of the shock results of the season when they were hammered 4-1 by bottom club Scunthorpe on Saturday.
The squad have stayed in Yorkshire to prepare for Tuesday night's trip to Oakwell and Warnock is demanding a response.
"You are going to get the odd freak result, we just have to get over it and get on with the Barnsley game," he said.
"It's always tough at Oakwell, just like it's tough at Scunthorpe. That what makes the league what it is. We've got to make it tough for Barnsley.
"It's about how we bounce back and we've always bounced back quite well."
