... or electrophysiological properties of putative respiratory neurons in slices without relevant synaptic inputs. Here, we detail a method to horizontally slice away the dorsal portion of the brainstem to expose fluorescently labeled motoneurons for patch-clamp recordings in American bullfrogs. This ‘semi-intact...

... currents are found to be much more stable than when measured using the conventional whole-cell (CWC) patch-clamp technique. Ca 2+ channel currents, which typically ‘wash out’ within a few minutes of the beginning of CWC recording, are stable for the duration of the seal (tens of minutes) when measured...

NET currents are elicited by application of guanethidine, a more stable substrate for NET than NE (NE currents can also be detected, although they are generally of smaller magnitude). SERT currents are observed after application of 5-HT. A slow...

In this report, we identify a membrane ion channel that is sensitive to membrane tension; this cation-selective ion channel may constitute one mechanism for the transduction of mechanical stimuli. In contrast to several other types of ion channels exhibiting spontaneous activity in our patch-clamp study...
