neuroscience
Neuroscience is the multidisciplinary study of nervous systems, integrating molecular biology, physiology, and computational modeling to understand how neural circuits give rise to learning, memory, and behavior. Although plants lack neurons, neuroscience concepts and methods have inspired the emerging field of plant neurobiology, which investigates analogous signaling networks — including electrical signals, calcium waves, and long-distance chemical communication — that allow plants to sense, integrate, and respond to environmental stimuli. These parallels offer fresh frameworks for understanding how plants process information and exhibit adaptive behaviors without a conventional nervous system.

A traditional Chinese herbal formula called Chaihu-Shugan-San (CSS) was shown to relieve functional dyspepsia — a chronic stomach disorder — by calming overactive pain signals in the brain and spinal cord and correcting imbalances in glutamate, a key brain chemical.
607 bioactive plant compounds were identified in the herbal formula, with 129 detected in rat blood and 134 reaching the brain, confirming the herbs cross the blood-brain barrier.
CSS treatment reduced inflammatory markers (Iba1, NOX2) in the amygdala and lowered spinal cord levels of pain-signaling proteins (CaMKII, NMDAR, IL-1β), indicating reduced central pain sensitization.
Metabolomics analysis showed CSS corrected glutamate metabolism pathways in both fecal and serum samples, linking gut microbial chemistry changes to improvements in brain signaling.
