兩棲類幼生のKyphosisについて

The kyphosis of amphibian larvae, which incidentally occurs in the experiments on the operation of the central nervous system, has often been reported. In the experiment of the excision of the brain with the Bufo vulgaris embryos which are older than the tail-bud stage, measuring 7mm in length, the kyphosis was produced when the hind-brain was taken off. Taking the descriptions of the previous investigators into consideration (Table2), the following conclusions were obtained: 1. The kyphosis of amphibian larvae is produced by the excision of the hind-brain, but neither by the excision of the fore-brain nor by the removal of the mid-brain. 2. It is highly probable that the disturbance or the excision of the notochord has no relation with the kyphosis. 3. The kyphosis is found to occur more frequently in the experiments in which the embryos of the later developmental stages are used.
