Human anaphylatoxin C5a injected directly to the perifornical hypothalamus (PFH) of the rat elicits food intake in sated rats, an effect which mimics that of norepinephrine (NE) at the PFH. The ability of C5a to induce food intake is selectively blocked by the alpha-adrenergic antagonist phentolamine, confirming that C5a exerts its effects via an(More)
Four observers completed identification and categorization tasks. Learning and attention processes were examined by applying general recognition theory (F. G. Ashby & J. T. Townsend, 1986), which separates perceptual, decisional, and attentional processes. Learning led to decision regions that became more nearly optimal. Learning had little effect on(More)
