The brain circuitry processing rewarding and aversive stimuli is hypothesized to be at the core of motivated behavior. In this study, discrete categories of beautiful faces are shown to have differing reward values and to differentially activate reward circuitry in human subjects. In particular, young heterosexual males rate pictures of beautiful males and(More)
1. We probed for the expression of electrogenic Na+/HCO3- co-transport in cultured mammalian astrocytes by recording voltage and current changes induced by bath application of HCO3-, with the use of patch-clamp electrophysiology. Application of 25 mM HCO3-, at a constant pHo, to astrocytes bathed in a nominally HCO3(-)-free solution, produced an abrupt and(More)
PURPOSE We studied Na+ channel expression and the ability to generate action potential (AP)-like responses in primary cultures of human astrocytes by whole cell patch-clamp recording techniques. METHODS Tissue samples from 22 patients with various classifications of temporal lobe epilepsy (TLE) were plated to form separate astrocyte cultures from three(More)
