Does the brain control salivary glands?

Yes, the brain controls salivary glands through the autonomic nervous system. Specifically, the salivary glands are regulated by signals from the parasympathetic nervous system, which stimulates saliva production, especially in response to food stimuli. The brain processes sensory information, such as the sight or smell of food, leading to increased salivation. Additionally, the sympathetic nervous system can inhibit saliva production during stress responses.
