Food CSs, presented (i) concomitantly with SD controlling bar pressing for food, or (ii) on the background of non-discriminated bar pressing (FR 1/15), suppress instrumental performance but elicit undiminished conditioned salivation. This result supports Soltysik-Konorski's model of CNS mechanism controlling food-oriented behavior which postulates drive inhibition by taste-consummatory neurons.

We read with considerable interest the paper by Shergill et al (2004) about the temporal course of brain activity associated with auditory verbal hallucinations. The researchers used functional magnetic resonance imaging to reveal those brain regions activated before, during and after such hallucinations (the occurrence of which was indicated by patients pressing a button). They concluded that ...
