MacLean (1990, 1993) Proposed That the Human Forebrain Includes Three

MacLean (1990, 1993) proposed that the human forebrain includes three distinct systems, each of which developed in a distinct phase of vertebrate evolution. According to MacLean, the striatal region is:

A) the earliest and most basic part of the forebrain.
B) the stream of movement.
C) the system that coordinates marking and patrolling of territory as well as forming social groups.
D) all of the above.
