The effects of hippocampal complex lesions on memory for location and color were assessed in black-capped chickadees (Parus atricapillus) and dark-eyed juncos (Junco hyemalis) in operant tests of matching to sample. Before surgery, most birds were more accurate on tests of memory for location than on tests of memory for color. Damage to the hippocampal complex caused a decline in memory for location, whereas memory for color was not affected in the same birds. This dissociation indicates that the avian hippocampus plays an important role in spatial cognition and suggests that this brain structure may play no role in working memory generally.
在大山雀(Parus atricapillus)和暗眼灯草雀(Junco hyemalis)的样本匹配操作性测试中,评估了海马复合体损伤对位置和颜色记忆的影响。手术前,大多数鸟类在位置记忆测试中的表现比在颜色记忆测试中更准确。海马复合体受损导致位置记忆下降,而同一批鸟类的颜色记忆未受影响。这种分离表明鸟类海马体在空间认知中起重要作用,并表明该脑结构通常可能在工作记忆中不起作用。
