The brain of Homo floresiensis was assessed by comparing a virtual endocast from the type specimen (LB1) with endocasts from great apes, Homo erectus, Homo sapiens, a human pygmy, a human microcephalic, specimen number Sts 5 (Australopithecus africanus), and specimen number WT 17000 (Paranthropus aethiopicus). Morphometric, allometric, and shape data indicate that LB1 is not a microcephalic or pygmy. LB1's brain/body size ratio scales like that of an australopithecine, but its endocast shape resembles that of Homo erectus. LB1 has derived frontal and temporal lobes and a lunate sulcus in a derived position, which are consistent with capabilities for higher cognitive processing.
通过将来自模式标本（LB1）的虚拟脑模与来自大猩猩、直立人、智人、人类侏儒、人类小头畸形者、标本编号Sts 5（南方古猿非洲种）以及标本编号WT 17000（埃塞俄比亚傍人）的脑模进行比较，对弗洛勒斯人（Homo floresiensis）的大脑进行了评估。形态测量、异速生长和形状数据表明，LB1不是小头畸形者或侏儒。LB1的脑/身体大小比例与南方古猿的比例相似，但其脑模形状类似于直立人。LB1具有衍生的额叶和颞叶以及处于衍生位置的月状沟，这与更高认知处理能力相符。
