Stephen Back Fetal Model Neurons Figure 1 (image) Oregon Health & Science University Share Print E-Mail Caption During normal brain development in our fetal model, neurons (brain cells) rapidly grow processes called dendrites that allow them to communicate with other neurons. In panel A, a neuron equivalent to that from a 28-week-old human fetus displays very few dendritic processes and appears very simple. Panel B shows that four weeks later, neurons appear to be much more complex with many dendritic processes and branches present.
