1. Spectral sensitivity measurements using the suction electrode technique reveal three types of cone in the retina of the tiger salamander, showing maximum sensitivity at wavelengths 610 nm (red-sensitive cone), 444 nm (blue-sensitive cone) and below 400 nm (UV-sensitive cone). 2. The absolute sensitivities of red- and blue-sensitive cones to flashes of(More)
Calcium is transported across the surface membrane of both nerve and muscle by a Na+-dependent mechanism, usually termed the Na:Ca exchange. It is well established from experiments on rod outer segments that one net positive charge enters the cell for every Ca2+ ion extruded by the exchange, which is generally interpreted to imply an exchange stoichiometry(More)
1. Membrane currents caused by the operation of electrogenic Na(+)-Ca2+,K+ exchange were recorded from isolated rod outer segments under voltage-clamp using a whole-cell electrode. 2. Reversed mode exchange currents (Na+i-Ca2+o,K+o) were recorded with a high internal [Na+] and when both Ca2+ and K+ were present in the external solution. Omission of either(More)
In this paper, an innovative educational approach to introducing undergraduates to both digital signal processing (DSP) and field programmable gate array (FPGA)-based design in a onesemester course and laboratory is described. While both DSP and FPGA-based courses are currently present in different curricula, this integrated approach reduces the number of(More)
Pursuant to Article 1 of the Convention signed in Paris on 14th December 1960, and which came into force on 30th September 1961, the Organisation for Economic Cooperation and Development (OECD) shall promote policies designed: − to achieve the highest sustainable economic growth and employment and a rising standard of living in Member countries, while(More)
