I've been reading about homeostatic nature of a lot of neurobiological processes - the brain is trying to maintain a balance by desensitizing receptors, re-uptaking and breaking down neurotransmitters.
With this in mind, I'm interested in what happens to the receptors in the brain with chronic use of caffeinated beverages. Let's say an occasional caffeine drinker likes the cognitive boost of caffeine and starts to consume it habitually/chronically - every day. Will the caffeine drinker experience the same effects day after day, or will the effect change over time?
If there is a change in how the body responds to caffeine, are there any time frames that can be used to estimate when the change takes place - is it X days/weeks of habitual use?
Thank you for your input!
