Perception of sound is initiated by mechanically gated ion channels at the tips of stereocilia. Mature mammalian auditory hair cells require transmembrane channel-like 1 (TMC1) for mechanotransduction, and mutations of the cognate genetic sequences result in dominant or recessive heritable
Shih-Wei Chou et al.
Nature communications, 8(1), 2234-2234 (2017-12-23)
Detection of water motion by the lateral line relies on mechanotransduction complexes at stereocilia tips. This sensory system is comprised of neuromasts, patches of hair cells with stereociliary bundles arranged with morphological mirror symmetry that are mechanically responsive to two

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
