HETEROCARRIER-MEDIATED RELEASE Finally, there is evidence that transporters for GABA are found on the terminals of neurons releasing other types of transmitters. Early attempts to treat PD with dopa failed because the doses used were too small.

More recently, a series of studies using microdialysis in vivo has suggested that long- latency changes in presynaptic 5-HT1A receptors could underlie the therapeutic lag in antidepressant treatment. In slices of rat medial habenula the synaptic currents, recorded with the whole-cell patch-clamp technique that were evoked by electrical stimulation in the presence of both glutamate and GABA antagonists, were inhibited by the P2x (P2x2 preferred) antagonist suramin and by ab-me-ATP an agonist that desensitises some P2x receptors but not normally the P2x2 form. As treating physicians, they are held to the standards of each relevant specialty. Modified approaches Given the potential sources of uncontrollable bias in all phases of the study, investigators may choose to use “paper” or videotaped patients or clinical vignettes, interactive computer simulated cases, or “standardised patients” especially trained to simulate a specific role consistently over time. The number of drug-related prosecutions was just under 130 000 in that year of which 90% were for possession, and the majority of the cases dealt with were cannabis.
It is remarkable that, although this theory is often challenged, it has not yet been replaced by a validated alternative and, to this day, central noradrenergic and/or serotonergic systems are primary targets for all established antidepressant drugs.

However,much better expression occurs with two or more subunit types in combination and it is likely that most native receptors contain at least three different subunits. In diagnostic research the term “confounding variable” is used in a different, more pragmatic sense than in aetiologic research, as consistent diagnostic correlations do not need to be fully causally understood to be useful. It is conceivable that, in the not-too- distant future, the use of online communication will become as com- monplace as the use of the telephone and there will be generally accepted norms for availability of clinicians to patients.
