A (p-)brane is a dynamically evolving physical object that generalizes the notion of a point particle to (p) higher dimensions. A point particle can be viewed as a brane of dimension zero, a string as a brane of dimension one, and a membrane (sheet) as a brane of dimension two. Do not use for particles or strings, however, unless in comparative juxtapositions.

In M-Theory are membranes excited states of a field? [duplicate]
Is there an underlying M brane field where the branes are excitations of the field? Or is the M brane simply a fundamental object made out of no fields?"
I am confused what an M Brane really is. … M2 membranes are strings when you compatify a membrane on a circle, if I am not wrong, so this means all strings and branes are really just solitons? …
