A bit of a detour into neuroscience today with a look at the chemical structures of some of the major neurotransmitters in the brain. Inspired in part by this post on the chemicals related to various emotions.

Fig 1. In 2008, bioengineers at the University of Minnesota stripped rat hearts of cells using detergent — you can see the results of three trials here. This process left untouched the blood vessels, collagen, and various proteins that compose the heart’s physical structure.
Fig 2. The ghost heart is flushed with red dye to show that major and minor blood vessels were left intact.
Fig 3. A researcher injects the ghost heart with heart cells from newborn mice.
Fig 4. Researchers adjusted the environmental conditions to simulate natural conditions, meaning they provided oxygenate fluids, pressure, and an electrical stimulus. You can see the bioreactor schematic here.
