While the nature of adenosine action on central circuits is not well understood, adenosine is thought to have an inhibitory or relaxing effect based on which observation?

Respuesta :

Adenosine is thought to have an inhibitory or relaxing effect based on the consequences of xanthine (e.g., caffeine) blockade of adenosine receptors.

The manner that xanthine (for example, caffeine) interacts with the adenosine receptors in the neuronal membrane is largely responsible for its stimulant effects. It is a neuromodulator of the central nervous system with particular receptors. Thus, adenosine promotes sleep and widens blood arteries, likely to ensure enough oxygenation while sleeping.

As an antagonist of the adenosine receptor, caffeine. In other words, it binds to the same receptors but does not inhibit neuronal activity. As a result, the natural "braking" effect of adenosine is less effective and brain activity increases.

Therefore, Adenosine is thought to have an inhibitory or relaxing effect based on the consequences of xanthine (e.g., caffeine) blockade of adenosine receptors.
