There was more than one way to get a look at the brain. Since the delicate way would get interrupted, he went for the brutal way.

He went to the leader that had been the only one having lost the ability to move.
After patting him up and down to see if the knowledge he got from his subordinate's body was the norm of their race, he plunged his clawed hands into his chest, and spread it apart violently. He saw what looked like organs inside, but they looked nothing like humans'. And either they had multiple roles each, or the alien had an illogical constitution.
A moment later, he looked at the three yellow pools and thought that maybe the eyes he thought were black, were just deep and concentrated yellow.
