Similarly, infreshly dissected hippocampal slices, electrical stimulation of the Schaffer collaterals, a glutama tergic fiber tract that connects neurons in the CA3 and CA1 fields, causes a Ca2+-dependent increase in 2-AG content . This stimulation has no effect on the levels of non-cannabinoid mono acylglycerols, such as 1-palmitoylglycerol, which indicates that 2-AG formation may not be attributed to a broad,…
