    Individual activation, left hemisphere.

    Activation patterns for the 2 subjects who participated in each experiment for (A) responsive naming and (B) confrontation naming. Blue, activation external to the temporal regions of interest; yellow, activation within the posterior temporal region of interest; and red, activation within the anterior temporal region of interest.
