Diazepam vs xanax for sleep problems is clearly far less exciting than the idea of a drug that alters whole brain layer. (Actually it is less interesting, since drugs like tranylcypromine, lithium, and verapamil do, in fact, alter the GABA structure of neurons. But they do not alter its function, they don't "change the way neurons behave".) In contrast, the GABAergic modulation of sleep is a more realistic target for drug exploration, since it is relevant across multiple brain areas.
To this end, two recent papers have used fMRI or PET electroconvulsive therapy experiments to show that modulating the neurotransmission at cellular level may alter the behaviour of sleeping dopamine neurons in the medial prefrontal cortex. These results lend some support to the idea that abnormal sleep regulation could result from defects in inhibitory control of glutamatergic synapses in the brain.
Neurologically, the study was a little bizarre, and I have written about its weird characteristics before. (Though it really shouldn't be.) I was glad to see that the author decided to rewind recordings and get a complete control buy diazepam us group, including non-drug-treated controls.
First off, the authors had idea that a drug which would lower endogenous GABA levels could mimic the action of benzodiazepines (see my last post for details about what I wrote above). However the key finding was that their fMRI experiment showed modulating the levels of GABA produced a large increase in the total amount of spontaneous sleep in wakefulness. The authors did not show that their drug modified GABA transmission directly, which would explain the increase in spontaneous sleep (they think that it shifts levels of GABA at the site inhibition, in combination with inhibition of some other cell types, but the mechanism isn't specified). They thought that the increase in sleep was caused by the increase in GABA activity, but I think that this is a gross misinterpretation, or at the very least an incorrect interpretation of the results.
Instead what the study really shows is that drug manipulations at the GABA receptors can enhance release at the site of GABA inhibition. (A paper like this would be particularly interesting for the potential use of such a technique in schizophrenia, by selectively inhibiting several type III GABA receptors, but I'm not aware of such a method being tested for its effectiveness in humans.) contrast to their results, people given a normal dose of benzodiazepines during waking hours had just as much sleep the non-drug-treated controls. So results clearly indicate that abnormal sleep regulation could result because benzodiazepine receptor dysfunction in the brain could cause an increased GABA release at the site of GABA inhibition.
This point was confirmed by another recent paper. This time it was a PET experiment, comparing non-drug (placebo) control with one given a GABA agonist to produce very "placebo" effect. Here the researchers manipulated GABA receptor function by blocking Type I and IIA GABA receptors, but the authors did not see any alteration in spontaneous sleep behaviour.
So, it looks like this type of selective inhibition the GABA receptors can make some differences in the quality of sleep a healthy brain, while in brain displaying a pathological deficiency, drugs can have a huge effect on sleep physiology.
It is the same paradoxical process in sleep regulation that is at diazepam buy online cheap uk work in schizophrenia. There are two main studies of this topic in schizophrenia, one the last 5 years, which showed a clear increase in sleep of schizophrenics taking a specific antipsychotic drug, while the other study showed "no effect" for the same drug, and both studies suggested a reduction in sleep quality patients as a consequence. These studies have huge advantage over the studies of sleep homeostasis, because they show direct alteration of the sleep physiology, as opposed to the results of a variety indirect changes in the sleep physiology at a level below the of consciousness.
The sleep homeostasis approach tries to explain why patients with schizophrenia have trouble sleeping. For example, the authors of study mentioned above were looking, for example, an impaired "lateral sleep-wake oscillator", as it was named at the time. diazepam buy cheap "lateral sleep-awake oscillator" suggests more oscillations in both directions the brain, as opposed to one-way oscillations in either direction. (Also, with regards to the drug studies, oscillatory activity is correlated with functional neurochemical changes in the brain, and since this activity corresponds with the sleep homeostasis, schizophrenia patients should look disturbed in this kind of sleep physiology.)
But schizophrenia is different in some important respects, for example that (I believe not only because of the role GABA in sleep homeostasis, but also because of the effect THC in schizophrenia patients during the transition to psychosis) it appears be a condition that affects relatively large number of neural pathways (of which some of involve GABA receptors) within the brain, but it seems to affect.
