Dissection of the dura or subdural meninges. (a) Representative tip of the tungsten needle used for dissecting only the dura (the needle was bended as a hook), displayed with two different scales in left and right panels. (b) Dissecting the dura, during which the tungsten needle was used to hook up the dura and then remove it, and subdural meninges were not touched by the needle. (c) The cortical surface after dissecting the dura. (d) A representative cortical surface with the dura and subdural meninges completely dissected
