Almgren, P.‐E., Andersson, A. L. & Kullberg, G. Differences in verbally expressed cognition following left and right ventrolateral thalamotomy. Scand. J. Psychol., 1969, 10, 243–249.—Patients with Parkinson's disease, subjected to ventrolateral thalamotomy, 44 on the left side and 23 on the right, were tested pre‐ and postoperatively with the Color‐Word Test (CWT), a memory test of word pairs (WPT), and Raven's Progressive Matrices Test (PMT). As to performance change from pre‐ to postoperative testing, there were significant differences between the two groups of operatees on the CWT (p =0.000001, at best) and the WPT(p = 0.01), implying a less effective postoperative performance in the group with left‐sided thalamic lesion. Such a lesion seems to impair the continuous suppression of previously relevant information in connection with selection of the appropriate verbal response.
