Lamina-specific membrane and discharge properties of rat spinal dorsal horn neurones in vitro.
Membrane and discharge properties determine the input-output relationship of neurones and are therefore of paramount importance for the functions of neural circuits. Here, we have tested the hypothesis that neurones in different laminae of the spinal dorsal horn differ in their electrophysiological properties. Whole-cell patch-clamp recordings from dorsal horn neurones in a rat transverse spina...
متن کاملPhorbol Ester Modulation of Ca2+ Channels Mediates Nociceptive Transmission in Dorsal Horn Neurones
Phorbol esters are analogues of diacylglycerol which activate C1 domain proteins, such as protein kinase C (PKC). Phorbol ester/PKC pathways have been proposed as potential therapeutic targets for chronic pain states, potentially by phosphorylating proteins involved in nociception, such as voltage-dependent Ca2+ channels (VDCCs). In this brief report, we investigate the potential involvement of...
متن کاملZinc (Zn2+) blocks voltage gated calcium channels in cultured rat dorsal root ganglion cells.
Dorsal root ganglion cells (DRGs) exhibit 3 types of voltage-dependent calcium channels. We have cultured DRGs from 2- to 4-day-old rat pups and obtained whole-cell patch-clamp recordings of calcium-channel currents after 1-5 days in culture. The calcium-channel currents (carried by barium) were recorded with tetrodotoxin (TTX) in the external solution. A cesium-based solution containing Na-ATP...
متن کاملCalcium-binding proteins calbindin and parvalbumin in the superficial dorsal horn of the rat spinal cord.
Neurons containing the calcium-binding proteins, calbindin or parvalbumin, were studied by immunohistochemistry in the superficial dorsal horn of the rat spinal cord. Calbindin-containing cells were found in laminae I, II and III, being more abundant in laminae I and II. Some of the neurons in lamina I containing calbindin projected to the supraspinal area. Parvalbumin-containing neurons were m...
متن کاملGlutamate-induced cytoplasmic Ca2+ transients in neurones isolated from the rat dorsal cochlear nucleus.
Extracellular application of glutamate elicited cytoplasmic Ca2+ transients in freshly dissociated rat neurones of the dorsal cochlear nucleus (DCN) (identified as pyramidal cells) with half-maximal concentration of 513 micromol/l while saturating doses (5 mmol/l) of this neurotransmitter caused transients of 46.1 +/- 3.0 nmol/l on an average. The genesis of these glutamate-evoked Ca2+ transien...
