In C. elegans and mouse neurons, the balance between poly(ADP-ribose) glycohydrolases and poly(ADP-ribose) polymerases regulates axon regeneration downstream of DLK-1/MAPKKK signaling.
The brain continues to represent individual fingers in primary somatosensory cortex decades after the amputation of a hand, indicating that cortical maps do not require ongoing sensory input from the body.

Clustered and non-clustered protocadherins form antiparallel homodimers in which distinct regions of the extended interface demonstrate a division of labor between driving affinity and determining specificity.
The compactness of synaptic release sites coupled with their four-fold number in humans compared to rats provides unprecedented scaleability in operation of human synapses.
