Colitis in Dogs. Colitis is an inflammation or irritation of the colon or large intestine and, you guessed it: it commonly causes diarrhea in our furry friends. Colitis can be acute (meaning it comes on suddenly) or chronic (lasting several weeks or longer, or recurring). There are several potential causes of colitis. They include:
Dopamine is a neurotransmitter released by the brain that plays a number of roles in humans and other animals. Some of its notable functions are in: 1  movement. 2  memory. 3  pleasurable reward. 4  behavior and cognition. 5  attention. 6  inhibition of prolactin production.
Cell membranes also control the release of neurotransmitters and this means that the release of neurotransmitters is also affected by the presence of alcohol. The effects of alcohol on receptors and neurotransmitters have been well documented for several neurotransmitters and their corresponding receptors.
