Beauty of the Brain

Neurons communicate with one another by releasing chemicals, such as dopamine, from pouches called vesicles. The vesicles, seen here in a fibroblast cell, have a geodesic outer coating that eventually pops through the side of the cell and releases its chemical message to be detected by the cell’s neighbors.
