Hemi Section Lesion

A hemi section lesion is an experimental injury in which one half of the spinal cord is surgically damaged or severed, allowing researchers to examine how specific neural pathways control movement and sensation. Because the lesion interrupts ascending and descending tracts on one side, it produces distinct, often side-specific changes in sensory processing, motor function, and reflex activity that reflect the organization of the spinal cord. In biology and neuroscience, hemi section lesions help map neural circuits, assess functional recovery, and investigate axonal regeneration, neural plasticity, and rehabilitation strategies after spinal cord injury.

We developed a method to successfully remove, process, section, and stain, for histopathological evaluation, mammary tissue that had originally been fixed on slides as whole mounts. This method may promote the collection and evaluation of mammary gland whole mounts in reproductive and developmental test guideline studies.
