Preventing blood vessel growth in the neurogenic areas of the brainstem interfered with normal neuron production, causing neural stem cells to lose their ability to reproduce.
However, the most intriguing finding of this study was that blood vessels did not regulate neural stem cell behavior in the brainstem simply through their role in brain oxygenation or keeping brain tissue healthy.
Walking-like activity could also be initiated by exposing the lower brainstem to blue light, demonstrating that excitatory cells in the brainstem provide a sufficient 'go' signal to the spinal neurons involved in walking.
The investigators reported that treating the PBC in rodent brainstems with a drug called riluzole didn't alter the recorded respiratory rhythm.
This brainstem area, called the pre-Botzinger complex, appears to drive both the normal, quiet breathing pattern and more complicated breathing actions such as sighs and gasps.
