How to subset 1.3M 10x Genomics dataset by tissue of origin

This may be a naive question, but is there a way to only use a subset of the 1.3million cells that are from, say, the cortex? Is there a vector associating cell name with tissue type, or are they all mixed in together with no way of separating out these three tissue types?
