Extracellular ATP is implicated in numerous sensory processes ranging from the response to pain to the regulation of motility in visceral organs. The ATP receptor P2X3 is selectively expressed on small diameter sensory neurons, supporting this hypothesis. Here we show that mice deficient in P2X3 lose the rapidly desensitizing ATP-induced currents in dorsal(More)
The HERMES experiment is collecting data on inclusive and semi-inclusive deep inelastic scattering of polarised positrons from polarised targets of H, D, and 3 He. These data give information on the spin structure of the nucleon. This paper describes the forward angle spectrometer built for this purpose. The spectrometer includes numerous tracking chambers(More)
Deep-inelastic Ô scattering data, taken with the H1 detector at HERA, are used to study the event shape variables thrust, jet broadening, jet mass, parameter and two kinds of differential two-jet rate. The data cover a large range of the four-momentum transfer É, which is considered to be the relevant energy scale, between Î and ½¼¼ Î. The É dependences of(More)
A search for excited fermions ¢ ¡ of the first generation in £ ¤ ¦ ¥ scattering at the col-lider HERA is presented using H1 data with an integrated luminosity of 37 pb § ¨. All electroweak decays of excited fermions, © ¡ ¢ © ! are considered and all possible final states resulting from the ! or hadronic decays or decays into leptons of the first two(More)
The elastic electroproduction of mesons is studied at HERA with the H1 detector for photon virtualities ½ É ¾ ½½ Î ¾ and hadronic centre of mass energies ¼ Ï ½¿¼ GeV. The É ¾ and Ø dependences of the cross section are extracted (Ø being the square of the four-momentum transfer to the target proton). When plotted as function of (É ¾ + Å ¾ Î) and scaled by(More)
