The accumulation of non‐vascular, non‐neuronal cells (designated herein as reactive cells)
in association with perikarya of axotomized motor neurons has been described by many …

The effects of sciatic nerve resection on lumbar dorsal root ganglion cells and their central
branches have been studied in the adult rat. A quantitative analysis of the lumbar dorsal root …

Transection of a peripheral nerve not only elicits changes in the injured neurons but also
results in an increase in non‐neuronal cells, considered by most workers to be neuroglia, in …

To label circulating blood mononuclear cells, adult male mice were given multiple injections
of tritiated thymidine on the day prior to transection of the right sciatic nerve. These animals …

1. Extracellular single-unit recordings have been made from 295 dorsal horn neurons in the
lumbar enlargement of rat spinal cord; 191 neurons in 20 rats with an experimental …

Tight ligation of the fifth and sixth lumbar segmental nerves in the rat provides a model of
neuropathic pain. We used this model to assess the changes in primary afferent input to the …

The regenerative processes which follow injury to a peripheral nerve have been studied
extensively, but little is yet known of the significance of the changes which take place in the …

RESULTS Our sections stained with Delafield's hematoxylin did not give information with
regard to the Nissl configuration in the cells. Nor did they reflect the presence or absence of …

MATERIALS AND METHODS The left sciatic nerves of 12 adult albino rats were exposed in
the mid-thigh using sodium pentobarbital anesthesia. In half of the animals the nerve was …

Proliferation of glial cells is one of the hallmarks of CNS responses to neural injury. These
responses are likely to play important roles in neuronal survival and functional recovery after …
