Burst "ring is a prominent feature of cortical pyramidal cells and is thought to have signi"cant functional roles in reliable signaling and synaptic plasticity. Modeling studies have successfully elucidated possible biophysical mechanisms underlying complex bursting in pyramidal cells. Based on these results (Pinsky, Rinzel, J. Comput. Neurosci. 1 (1994) 39}60), we have built a simpli"ed two-co...

Body size is one of the most important determinants of energy metabolism in mammals. However, the usual physiological variables measured to characterize energy metabolism and heat dissipation in endotherms are strongly affected by thermal acclimation, and are also correlated among themselves. In addition to choosing the appropriate measurement of body size, these problems create additional comp...

The first response of brown adipocytes to adrenergic stimulation is a rapid depolarizing conductance increase mediated by alpha-adrenergic receptors. We used patch recording techniques on cultured brown fat cells from neonatal rats to characterize this conductance. Measurements in perforated patch clamped cells showed that fast depolarizing responses were frequent in cells maintained in culture...

We have investigated the effect of the long-range Coulomb interaction on the one-particle excitation spectrum of n-type germanium, using tunneling spectroscopy on mechanically controllable break junctions. At low temperatures, the tunnel conductance shows a minimum at zero bias voltage due to the Coulomb gap. Above 1 K, the gap is filled by thermal excitations. This behavior is reflected in the...

Cellulose acetate phthalate (CAP)membrane was interacted separately with aqueous HCl solution and aqueous HCl with sodium dodecyl hydrogen sulphate (SDS) as a surfactant and their characteristic properties were determined on the basis of water content, conductance-time and membrane potential data. The possibility of electrochemical modification of cellulose acetate phthalate membrane upon immob...
