Five stages of embryonic development
WebEnvironmental changes, such as temporary anoxia, during the embryonic stage can impair brain development in leopard geckos (Eublepharis macularius). We therefore tested whether this early brain damage produces persistent behavioral deficits. The organization and kinematic properties of non-visual exploration between normal (n = 5) and anoxia (n …
