Calcium-independent, cGMP-mediated light adaptation in invertebrate ciliary photoreceptors.
Calcium is thought to be essential for adaptation of sensory receptor cells. However, the transduction cascade of hyperpolarizing, ciliary photoreceptors of the scallop does not use IP3-mediated Ca release, and the light-sensitive conductance is not measurably permeable to Ca2+. Therefore, two typical mechanisms that couple the light response to [Ca]i changes seem to be lacking in these photore...
متن کاملIntracellular recordings from gecko photoreceptors during light and dark adaptation
Intracellular recordings were obtained from rods in the Gekko gekko retina and the adaptation characteristics of their responses studied during light and dark adaptation. Steady background illumination induced graded and sustained hyperpolarizing potentials and compressed the incremental voltage range of the receptor. Steady backgrounds also shifted the receptor's voltage-intensity curve along ...
متن کاملIntracellular pH and intracellular buffering power of the cat brain.
ROOS, ALBERT. Intracellular pH and intracellular buffering power of the cat brain. Am. J. Physiol. 2og(6): 1233-1246. 1965.~In 49 cats the intracellular pH (pHi) of the brain was estimated from the distribution of 5,5-dimethyloxazolidine-2 ,4-dione2-Cl4 (DMO) between brain, plasma, and CSF, at arterial pCOz of 14.5-83.2 mm Hg. From six cats cortical biopsies were taken; in the remainder, brain ...
متن کاملLight Adaptation in Drosophila Photoreceptors
Besides the physical limits imposed on photon absorption, the coprocessing of visual information by the phototransduction cascade and photoreceptor membrane determines the fidelity of photoreceptor signaling. We investigated the response dynamics and signaling efficiency of Drosophila photoreceptors to natural-like fluctuating light contrast stimulation and intracellular current injection when ...
متن کاملIntracellular pH and intrinsic H+ buffering capacity in normal and hypertrophied right ventricle of ferret heart.
OBJECTIVE To answer the questions: (a) What is the effect of hypertrophy on the intracellular pH (pHi) and buffering power of cardiac muscle, and (b) How does hypertrophy affect the ability of cardiac muscle to recover from intracellular acidosis induced by hypoxia. METHODS In nominally HCO3(-)-free, HEPES-buffered Tyrode solution (35 degrees C), pHi and the intrinsic buffering power (beta i,...
