Sentience is effectively the same thing for the alien team as Build Points are for the human team. It is a measure of the remaining strength of the collective consciousness that controls all alien structures. Each structure built needs some of this in order to function, providing a cap to the amount of building the alien team can control.
Unlike creep, sentience has unlimited range and can control buildings anywhere as long as there is an overmind somewhere on the map. Should the overmind be destroyed then all buildings (other than eggs) will cease to function, although will not be destroyed as long as they still have creep.
Players commonly refer to Sentience as Build Points or 'BPs'.
When playing as the Granger Class the amount of Sentience available is displayed in the bottom right corner of the HUD.
