James Fallon, Sophie Payne DOI:10.17504/protocols.io.bfwyjpfw SPARC Recording electrically-evoked compound action potentials (ECAPs) is performed to confirm that the electrode array is appropriately placed along the nerve. Recording ECAPS also allows confirmation that electrical stimulation is above neural threshold i.e. that electrical stimulation activates neural activity. The procedure is performed under anesthesia (immediately post-surgery) or in awake animals, and the procedure should incorporate all local requirements for standards of animal experimentation.

Muriel Larauche, Yushan Wang, Po-Min Wang, James Dunn, Wentai Liu, Mulugeta Million DOI:10.17504/protocols.io.3rmgm46 SPARC This protocol describes a process for the measurement of acute electrical stimulation-induced effects on colonic motility in anesthetized young adult Yucatan minipigs. Signals recorded from manometry probes inserted into the proximal, transverse and distal colonic regions were used to measure the effect of stimulation by serosally placed electrodes opposed to the colonic tissue at multiple sites in an acute anesthetized preparation. The effect of stimulation was quantified as motility index assessments before, during and after stimulation, and the data was used to create a functional map of colonic motor response to localized colon stimulation.

Coleman, Kevin Otto, Martha Campbell Thompson DOI:10.17504/protocols.io.9gbh3sn Human Cell Atlas Method Development Community, Optical Clearing of Tissue, SPARC Using traditional histological methods, researchers are hampered in their ability to image whole tissues or organs in large-scale 3D. Histological sections are generally limited to 500 μm using traditional methods. In addition, light scatters from macromolecules within tissues, particularly lipids, prevents imaging to a depth >150 μm with most confocal microscopes. To reduce light scatter and to allow for deep tissue imaging using simple confocal microscopy, various optical clearing methods have been developed that are relevant for rodent and human tissue samples fixed by immersion. Several methods are related and use protein crosslinking with acrylamide and tissue clearing with sodium dodecyl sulfate (SDS). Other optical clearing techniques used various solvents though each modification had various advantages and disadvantages. Here, an optimized passive optical clearing method is described for studies of the human pancreas innervation and specifically for interrogation of the innervation of human islets.
