For decades,researchers have known that when neurons l.se their activating inputs,they can atrophy and even *** exampl.,removing sensory nerve inputs from the arm to the spinal.cord after amputation or cutting the spinal.nerves can shrink the post-synaptic target zones(e.g.,Woods et al.,2000).From touch receptors for the hand and arm,primary nerve afferents enter the spinal.cord,and axons travel.in the dorsal.col.mns to target the cuneate nucl.us(Cu)of the brainstem on the same side of the body(Figure 1).When sensory l.ss is unil.teral.the overwhel.ing resul. is for the associated primary target zone to shrink in total.size(cross-sectional.area),as compared to the size of the opposite side.
