The mammalian neuromuscular junction has been extensively studied by different methods to understand better the biological aspects of its normal development, ageing and pathological conditions, such as disorders of neuromuscular transmission. In the present report, a new technique is described

A simple and reliable method is described for staining the nerve plexuses of the human gastrointestinal tract in whole-mounts. The staining does not require fixation and consists of a single step of 6 to 10 minutes incubation in a solution

In this study we use nystatin perforated-patch and conventional whole-cell recording to characterize the biophysical properties of neuronal nitric oxide synthase (nNOS)-expressing paraganglion neurons from the rat glossopharyngeal nerve (GPN), that are thought to provide NO-mediated efferent inhibition of carotid

Remodeling of the synaptic extracellular matrix (ECM) and its dynamic relationship with nerve terminal plasticity have been demonstrated in normal frog neuromuscular junctions (NMJs) in vivo (Chen et al., 1991). Our previous work has led to a hypothesis that extension
