The sulci and gyri of the neocortex, as well as cyto-, synaptoarchitectonics and neuronal composition of the sensomotor (brain area) have been studied in the Baikal ringed seal. The structure of the sulci and gyri have been found to be similar to that in carnivores. The following specific features have been revealed in the brain of this endemic species: a thick layer I, presence of giant pyramidal cells in the layer III, large mitochondria in the presynaptic parts and dendrites. The results obtained are discussed concerning adaptation to semiaqueous way of life and to diving.
在贝加尔环斑海豹中研究了新皮质的沟回以及感觉运动（脑区）的细胞结构、突触结构和神经元组成。已发现其沟回结构与食肉动物的相似。在这种特有物种的大脑中发现了以下特定特征：I层较厚，III层存在巨型锥体细胞，突触前部分和树突中有大型线粒体。讨论了所获得的结果与对半水生生活方式和潜水的适应性之间的关系。
