In mammalian central neurones, the soma-dendritic spike is generally followed by afterpotentials, a brief depolarizing potential (delayed depolarization) and a more longlasting afterhyperpolarization (AHP). These afterpotentials, and in particular the AHP, have long been considered as important factors in the control of excitation-to-frequency transduction.(More)
To Christine Chodkiewicz-Putinar, who has enriched and inspired us by adding a second viola to our quartet Abstract. Growth estimates of complex orthogonal polynomials with respect to the area measure supported by a disjoint union of planar Jordan domains (called, in short, an archipelago) are obtained by a combination of methods of potential theory and(More)
"Functional antagonism" is often used to describe the general relaxant effect of beta 2 agonists and xanthines and their ability to protect the airways against bronchoconstrictor stimuli. This study in guinea pig isolated trachea addresses the question of whether the capacity of these drugs to protect against constrictor stimuli is related to smooth muscle(More)
Cooperative effects between afferents on the induction of long-lasting potentiation (LLP) of synaptic transmission were examined in the CA1 region of the hippocampal slice preparation. Synaptic activity was recorded extracellularly in the dendritic layer (stratum radiatum) as a field EPSP, and the amount of LLP produced was measured from the change in slope(More)
