title: [The effect of blockade of the AMPA/kainate receptors of the nucleus accumbens on synaptic dopamine release during an emotional conditioned response].
abstract: In vivo microdialysis combined with HPLC-EC analysis was used to monitor extracellular dopamine in the medial nucleus accumbens of rats. A conditioned emotional response to a contextual cue was accompanied by a prolonged release of dopamine in the nucleus accumbens. AMPA/kainate antagonist CNQX (100 mcM, intra-accumbens) had no effect on the conditioned dopamine release during the conditioned emotional responses. The data indicate that AMPA/kainate receptors of the nucleus accumbens are not involved in the regulation of the conditioned dopamine release.
