Although the exact cause of Parkinson’s disease (PD) is unknown, scientific research suggests that mutations in genes such as Parkin and PINK1 have a significant role in the progression of PD. These genes are involved in helping to maintain the health of cells, in part through their actions on mitochondria, the part of the cell whose function is to produce energy and to regulate metabolism.
The ability to remember sounds, and manipulate them in our minds, is incredibly important to our daily lives — without it we would not be able to understand a sentence, or do simple arithmetic. New research is shedding light on how sound memory works in the brain, and is even demonstrating a means to improve it.
Axonal damage is the major culprit underlying disability in conditions such as spinal cord injury and stroke. Andrew Kaplan, a PhD candidate at the Neuro, discovered that fusicoccin-A and similar molecules could be the starting point to develop drugs that treat axonal damage.
