Visual intensity difference thresholds were studied before and after telencephalic lesions in pigeons. Subjects with visual Wulst lesions showed initial postoperative threshold elevations that represented losses of 19%-49% of their preoperative sensory capacity. This initial loss was correlated with the extent of damage to three components of the visual Wulst: nucleus intercalatus hyperstriati accessorii, hyperstriatum intercalatus suprema, and hyperstriatum accessorium. The damage to hyperstriatum dorsale, another component of the visual Wulst, made no contribution to the initial deficit. The sensory capacity of all but one pigeon improved as a result of postoperative retraining.
研究了鸽子端脑损伤前后的视觉强度差异阈值。视觉中脑嵴损伤的实验对象术后初期阈值升高，这相当于术前感觉能力丧失了19%-49%。这种初期丧失与视觉中脑嵴三个组成部分的损伤程度相关：副超纹状体间插核、上超纹状体间插核和副超纹状体。视觉中脑嵴的另一个组成部分——背侧超纹状体的损伤对初期缺陷没有影响。除一只鸽子外，其他所有鸽子的感觉能力通过术后再训练都得到了改善。
