these results suggest that in the neonatal ca3 hippocampal region, when synchronous giant polysynaptic gabaergic psps are present (i.e., under basal, control conditions), spontaneously released gaba reaches a critical level and activates gabab receptors on both pyramidal cells and interneurons thus regulating the level of glutamatergic and gabaergic activity in the ca3 neuronal network. |

(2) this transporter can be encountered in excitatory axons using glutamate as neurotransmitter (hippocampal and cerebellar mossy fibres: primary afferent fibres), as well as in inhibitory axons known by their gabaergic nature (purkinje cell axon terminals) where it might be involved in the re-uptake process of one or several molecules released from corresponding terminals. |

the results suggest that (a) ampa/kainate receptors linked to the no/cgmp pathway in the hippocampus (but not nmda receptors) are tonically activated and kept in a desensitized state by endogenous glutamate; (b) blockade of ampa/kainate receptor desensitization by cyclothiazide leads to endogenous activation of nmda receptors; (c) the hippocampal no/cgmp system is under a gabaergic inhibitory tone driven by non-nmda ionotropic receptors; (d) the pre-convulsive episodes observed depend on hippocampal nmda receptor activation but not on no and cgmp production. |

to conclude: (a) extracellular hippocampal cgmp is controlled by inhibitory gaba(a) and gaba(b) receptors tonically activated through gabaergic interneurons receiving ampa/kainate-mediated glutamatergic inputs; (b) the gabaergic receptors are not endogenously saturated and can be further stimulated by exogenous agonists; (c) blockade of the gaba-mediated inhibition causes increase of cgmp and epileptic-like behaviour, due largely to endogenous activation of nmda receptors; (d) reproducible cgmp responses to ampa can be observed when the inhibitory gabaergic inputs to the no/guanylyl cyclase system are blocked, confirming the previously proposed existence of ampa/kainate receptors able to increase the nucleotide synthesis. |

in summary, these results provide direct evidence for more than one subtype of functional nachr in ca1 neurons and suggest that activation of nachrs present in gabaergic interneurons can evoke inhibitory activity in ca1 pyramidal neurons, thereby modulating processing of information in the hippocampus. |
