In the behaving rat, the consumption of an unfamiliar taste
activates the extracellular signal-regulated kinase 1-2 (ERK1-2) in
the insular cortex, which contains the taste cortex. In contrast, consumption of a familiar taste has no effect. Furthermore, activation of ERK1-2, culminating in modulation of gene expression, is obligatory for the encoding of long-term, but not short-term, memory of the new
taste (Berman et al., 1998). Which neurotransmitter and neuromodulatory systems are involved in the activation of ERK1-2 by the unfamiliar taste and in the long-term encoding of the new taste information? Here
we show, by the use of local microinjections of pharmacological agents
to the insular cortex in the behaving rat, that multiple neurotransmitters and neuromodulators are required for encoding of
taste memory in cortex. However, these systems vary in the specificity
of their role in memory acquisition and in their contribution to the
activation of ERK1-2. NMDA receptors, metabotropic
glutamate receptors, muscarinic, and -adrenergic and dopaminergic
receptors, all contribute to the acquisition of the new taste memory
but not to its retrieval. Among these, only NMDA and muscarinic
receptors specifically mediate taste-dependent activation of ERK1-2,
whereas the -adrenergic function is independent of ERK1-2, and
dopaminergic receptors regulate also the basal level of ERK1-2
activation. The data are discussed in the context of postulated novelty
detection circuits in the central taste system.
