Dorsal" refers to the back side of the body whereas "ventral" refers to the front side of the body.
When discussing bipeds, these terms are interchangeable with. Dorsal-ventral polarity is established by the gradient of a transcription factor called Dorsal.
Unlike Bicoid, whose gradient is established within a syncytium,. Dorsal-Ventral axis in developing embryo. Experiments performed on developing frog embryos in regards to. In this review, we will reconcile these theoretical ideas on the dorsal and ventral attentional system with recent empirical findings from human neuroimaging.
