猫脳尾状核の細胞構築学的研究ならびに痙攣時の組織化学的研究 第1編 猫脳尾状核各分野の神経細胞の大さと密度とに関する研究

According to the Gurewitsch classification, the caudate nucleus was devided into the areas of Cd., Cm., Cl. and Cv. and the size (long diameter) and density were measured. 1) Each area has two kinds of nerve cells with different size and the cell larger than 24 μ is called the large cell (so-called the effective cell of Gurewitsch), and smaller called the small cell (so-called the receptive cell of Gurewitsch). 2) The density of the large cells is 1.8% at Cd., 1.5% at Cm., 0.8% at Cl. and 0.2% at Cv., thus the dorsolateral side of the caudate nucleus (Cd. and Cm.) has more large cells with even larger size than the ventromedial side (Cl. and Cv.). 3) The density of the nerve cells is increasing from the dorsolateral side to the ventromedial and has the following rate: Cd. 9, Cm. 10, Cl. 11 and Cv. 13.
