When administered microelectrophoretically, a sulphonic acid derivative of baclofen, 3-amino-2-(4-chlorophenyl)-2-hydroxy-propylsulphonic acid, reversibly reduced the presynaptic reduction by (-)-baclofen of the monosynaptic excitation of spinal interneurones by impulses in low threshold primary afferent fibres of the cat as well as the

The supramammillary nucleus (SUM), a dorsal layer of the mammillary body, has recently been implicated in positive reinforcement. The present study examined whether GABA(A) receptors in the SUM or adjacent regions are involved in primary reinforcement using intracranial self-administration procedures.
Recent evidence has suggested that compounds affecting GABAergic transmission may provide useful pharmacological tools for the treatment of cocaine addiction. Using a rat model of self-administration, the present study examined the effects of GABA agonists and antagonists injected directly into
The effect of baclofen, a GABA(B) agonist, has been studied in the hot plate test in mice, to analyze the possible involvement of the GABAergic system in baclofen analgesia. Baclofen (1-3 mg kg(-1) intraperitoneal (i.p.)) was found to elicit a

In the mature nervous system excitatory neurotransmission mediated by glutamate is balanced by the inhibitory actions of GABA. However, during early development, GABA acting at the ligand-gated GABAA Cl- channel also exerts excitatory actions. This raises a question as to
