Yes, glucagon does affect the brain. Specifically, pancreas-secreted glucagon functions as a neurohormone within the brain, activating central pathways linked to blood glucose regulation.
Glucagon's Role in the Brain
The reference provided highlights the significant role of glucagon as a neurohormone, directly impacting the brain. Here's a breakdown of its function:
- Neurohormone Activity: Glucagon acts as a signaling molecule within the brain, similar to other neurohormones.
- Central Pathways Activation: It activates specific pathways in the brain related to the regulation of blood glucose levels.
Understanding the Impact
Glucagon's influence on the brain's central pathways is crucial for maintaining glucose homeostasis. This suggests a complex interplay between the pancreas (where glucagon is secreted) and the brain in regulating blood sugar.
