A cross section of a bundle of nerve fibers. Axons (orange) are wrapped in myelin (purple); an extension of the membrane of glial cells. Myelin has high lipid content, and acts to insulate the axons, causing them to transmit nerve impulses much faster.
Aphasia is multidimensional, meaning that it has many forms. There is no generic form. This info-graph helps show where damage occurs for each type of Aphasia and color coordinates with a chart to briefly explain what type of symptoms you would see.
Flashy Fluorescent Fish: Neurons in a larval zebrafish are distinguished using the Brainbow method, in which different ratios of a handful of colored fluorescent proteins are expressed randomly to give each neuron a unique hue.
