Pain "main switch"

NIPS-led researchers measured the heightened pain response when mice with a leg nerve injury were poked on the underside of a hind paw with a fine filament. Simultaneous live imaging of calcium ions in the brain's S1 cortex showed that certain signaling pathways were activated in astrocytes, a type of cell that helps neurons. Certain signaling pathways in S1 astrocytes were activated and triggered S1 cortex rewiring, contributing to mechanical hypersensitivity (allodynia). Such astrocyte-mediated changes in the brain may provide new clues for novel therapeutic strategies for treating debilitating mechanical allodynia

Wouldn't that be great! I'm not getting too excited yet though.....



As someone with 24/7 pain, yes it would be great BUT my immediate thought was did they also cause the injury to the poor mouse. I would sooner suffer my own pain than innocent animals be harmed.


That's a whole new 'massive' debate; I totally agree with you but the politics of it probably wouldn't be tolerated by the moderators!!

Just read my mind , poor mice , wire us up see what it really does and how did the move get the injury? I'm all for moving forward with research but use us first.
