A quantitative study of spinothalamic neurons in laminae I, III, and IV in lumbar and cervical segments of the rat spinal cord

Abstract

AbstractConfocal laser scanning microscope image of a neurokinin 1 receptor‐expressing spinothalamic tract neuron in lamina III of the rat cervical spinal cord. The neuron, which is shown in a parasagittal section (dorsal to the top), contains cholera toxin B subunit (red) that was transported from the posterior triangular nucleus of the contralateral thalamus, and is outlined by immunoreactivity for the neurokinin 1 receptor (green). It has prominent dorsally directed dendrites that enter the superficial laminae of the dorsal horn. J. Comp. Neurol. 511:1–18, 2008. © 2008 Wiley‐Liss, Inc.
