Implications for brainstem recovery from studies in primates after sensory loss from arm

引用

Neural Regeneration Research 2024年第3期19卷 479-480页

作者： jamie l.Reed Hui-Xin Qi Jon H.Kaas Department of Psychology Vanderbilt UniversityNashvilleTNUSA

For decades,researchers have known that when neurons lose their activating inputs,they can atrophy and even *** example,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 columns to target the cuneate nucleus(Cu)of the brainstem on the same side of the body(Figure 1).When sensory loss is unilateral,the overwhelming result is for the associated primary target zone to shrink in total size(cross-sectional area),as compared to the size of the opposite side.

Does the Brain Regulate the Immune System?While long considered to be separate entities,increasing evidence has demonstrated that thebrain and theperipheral immune system interact through bidirectional feedback[1].The brain hosts a vibrant immune environment(*** and perivascular macrophages)that is responsible for maintaining the integrity of the central nervous system[2].In addition,the brain is the central regulator of the rest of the body and its homeostasis.
