Perineuronal Nets (PNNs)
Perineuronal nets form during postnatal development, marking the end of what’s known as the “critical period” of heightened brain plasticity. PNNs are composed of extracellular matrix (ECM) molecules and are responsible for synaptic stabilization in the adult brain. PNNs are found around certain neuron cell bodies and proximal neurites in the central nervous system. Increasingly, researchers are turning to PNNs as potential targets to enhance plasticity for the treatment of various diseases. This illustration was created for the cover The Scientist magazine.

Common Disc Injuries
These illustrations were created for a medical device company to describe common spinal disc injuries. Intervertebral discs act as cushions between vertebrae in the spine. Degenerative disc disease is a term used to describe the changes to spinal discs as we age. When a disc bulges, it can put pressure on the spinal nerves, causing pain. In herniated discs, the jelly-like fluid within the disc leaks out due to a rupture in the annulus. This also causes pressure on the spinal nerves and pain.
