Abstract

Altering the early olfactory environment of animals can have dramatic consequences on the development of brain regions which subserve olfaction. The present study indicates that early odor deprivation has a more severe effect on a species which is born relatively mature than it does on related species which are not. The results call into question prevailing notions about the developmental continuity between animals born in divergent ontogenetic states.

摘要

改变动物早期的嗅觉环境会对服务于嗅觉的脑区发育产生显著影响。本研究表明，早期气味剥夺对出生时相对成熟的物种的影响比对相关的未成熟物种更为严重。这些结果质疑了关于处于不同个体发育状态的动物之间发育连续性的普遍观念。
