Key Findings:  This extensive review covers the existing evidence of the distribution of CB2 in several brain areas and different brain cells like neurons and glial cells, and notes that CB2 may directly regulate the immune system and the neuronal circuits, and regulate inflammation, mood, and cognitive functions.
