Samples of brain anterior temporal cortex from 17 patients with Alzheimer's disease and 18 age-matched controls have been analysed for myo-inositol and the three phosphoinositides. There was significantly less phosphatidylinositol in the Alzheimer samples (1.36 mumol/g wet weight) than in the controls (2.28 mumol/g). The concentrations of(More)
The secretion of catecholamines and the labelling of phospholipids with 32Pi has been studied in slices of bovine adrenal medulla. Both nicotinic and muscarinic drugs provoked catecholamine secretion, but only muscarinic activation was accompanied by the increased labelling of phosphatidylinositol and phosphatidic acid.
The (recent, Bayesian) cognitive science literature on the Wason Task (WT) has been modeled largely after the (not-so-recent, Bayesian) philosophy of science literature on the Paradox of Confirmation (POC). In this paper, we apply some insights from more recent Bayesian approaches to the (POC) to analogous models of (WT). This involves, first, retracing the(More)
Phosphoinositides of chick and rat retina were labelled with [3H]inositol. Exposure of retinal preparations to light for 30 s caused loss of labelled phosphatidylinositol 4,5-bisphosphate and to a smaller extent of the other phosphoinositides. Similar light-induced changes were seen when rod outer segment preparations were used and, when these were(More)
