英文摘要
Our long term goal is to determine the nature of functional or structural
reorganization that occurs in the primate spinal cord following
anterolateral cordotomy, and to correlate these changes with loss and
subsequent recovery of sensory function. Such delayed recovery of sensory
function occurs commonly in humans following an initially successful
cordotomy. Experimental work will center upon a search for change in
neuronal connectivity within the spinal dorsal horn. Research on the
neural reconnectivity of the primate dorsal horn has already been funded
under NIH grant #NS14899.
The immediate goal is to create a model of neural reorganization after
cordotomy in the rat, using anatomic, physiologic, and immunocytochemical
techniques applicable to the primate experiments, but without reference to
behavioral changes. This model may indicate the most fruitful
investigative techniques to be used in the monkey rapidly and at relatively
low cost. Initial emphasis will be placed upon demonstrating differences
between control and experimental animals in (1) the central arborization
patterns of primary afferent fibers, and (2) the immunocytochemical
staining patterns of peptides within the dorsal horn. The completeness of
spinothalamic tract section and the extent of ipsilateral spinothalamic
tract projections will be assessed through retrograde HRP studies.
In the future, the techniques that seem most promising in the rat model
will be emphasized in the primate experiments. Changes in functional or
structural organization of the primate dorsal horn will be correlated with
loss and recovery of sensory function after cordotomy, through behavioral
testing parameters already in use in this laboratory. This project
provides an ideal opportunity for the candidate to pursue her research
interests, while learning anatomic, physiologic, and immunocytochemical
investigational techniques.
