Repetition and the brain: neural models of stimulus

We focus primarily on studies using visually presented objects and their effects on the ventral object processing stream, to maximize overlap between monkey an ...

Neural crest cells and axonal specificity
... One of the most exciting features of neural crest cells is their pluripotency. A single neural crest cell can differentiate into any of several different cell types, depending on its location within the embryo. For example, the parasympathetic neurons formed by the vagal (neck) neural crest cells pr ...

We show in section 4.2 that the resulting regions are still an over-segmentation of the manual labeling. ...
