The effects of amphetamine on blocking

In the blocking paradigm, prior conditioning to one stimulus, A, interferes with conditioning to a second stimulus, B, when the two are reinforced as a compound in subsequent training. The present experiment employed a conditioned emotional response (CER) procedure with rats to examine the effects of 1.5 mg/kg dl-amphetamine on blocking. The drug was administered in a 2 x 2 design, that is, dru...

Front blocking and propagation in cylinders with varying cross section

In this paper we consider a bistable reaction-diffusion equation in unbounded domains and we investigate the existence of propagation phenomena, possibly partial, in some direction or, on the contrary, of blocking phenomena. We start by proving the well-posedness of the problem. Then we prove that when the domain has a decreasing cross section with respect to the direction of propagation there ...
