About this clipart
The image maps the neurobiological cascade initiated by stress, starting with prefrontal cortex (PFC), hippocampus (HIPP), and amygdala (AMG) inputs to the hypothalamus (HYP), which releases CRF to stimulate ACTH from the anterior pituitary and cortisol from adrenal glands. Concurrently, the vagus nerve modulates gut activity and immune responses, while enteric microbiota influence CRF release, GI motility, and mast cell activation-highlighting bidirectional communication in the brain-gut-immune network.
Used in medical, neuroscience, or functional medicine articles explaining psychoneuroimmunology, IBS, anxiety-gut links, or stress-related disorders; targets clinicians, researchers, and informed patients seeking mechanistic understanding.
