About this Research Topic
The PAG is a critical relay of the limbic brain and maintains strong connections to autonomic control circuits located in the brainstem and spinal cord. The PAG controls and relays limbic commands to body systems for mediating survival challenge (flight/fright) and/or emotional expression (vocalization, crying, singing). Yet the PAG, the ’survival generator’ in the brain is poorly understood. This theme will bring together original papers from physiologists, biologists and imaging experts on the state-of-art of the field.
