Teaching an old dog new tricks: Neuroscience research at IU combines centuries-old methods with modern technology

A photograph of a neuron (left panel) is shown next to an illustration of the same neuron (right panel). Left panel: The image background is brown. A single neuron is shown. The cell body is black and ovular, and dendritic branches look like sinuous lines extending from the cell body. A single dendrite extends from the top of the cell body, and multiple dendrites extend from the base. Right panel: A multicolor illustration of the neuron pictured in the left panel. The image background is black. The cell body and each dendritic tree is shown in a different color (dark blue, light blue, pink, green, and yellow). Parts of the dendritic tree that were out of focus in the left panel are clearly reconstructed in the right panel; the size and shape of each dendrite is otherwise identical between the two panels.

This post is the second installment in a two part series. Check out last week’s post here. Thanks to modern technology, the field of cellular neuroscience has become illuminated with brightly colored images – tissue samples, cells, and individual molecules have been stained, photographed, colorized, and even reconstructed in three dimensions. A Google Image search… Read more »
