Stimulus compatibility effects of an accessory visual stimulus on auditory sensitivity

Thomas F. Seif, James H. Howard
1975 Perception & Psychophysics  
Visual stimulus intensity (arousal), processing demand, and interstimulus compatibility (same or opposite direction of change of primary and secondary stimuli) were manipulated.  ...  The facilitative effect has been attributed to an arousal or warning process, while the interference effect has been characterized as a result of limited channel capacity.  ...  In each of the four studies that manipulated accessory stimulus intensity, facilitation occurred when the direction of stimulus change was identical for both the primary and secondary stimuli (i.e .. intensity  ...

Density-dependent changes of the pore properties of the P2X2receptor channel

1993 Biophysical Journal  
Decreased pH also leads to changes in ion channel function and to changes in the secondary structure of the acetylcholine receptor in membranes containing ionizable phospholipids.  ...  Lipids such as phosphatidic acid may serve as allosteric effectors for membrane protein function and the lipid-protein interface could be a site for activity-dependent changes that lead to modulation of  ...  The pHdependent changes in the ion channel activity of reconstituted membranes containing phosphatidic acid correlate directly with the calculated ionization properties of the protein-associated phosphatidic  ...
