Neurotransmission in the brain by diffusion through the extracellular fluid: a review.

abstract：:delta-9-Tetrahydrocannabinol (THC) is a major psychoactive component of cannabis. We have recently localized a receptor for THC in the forebrain and found in the caudate-putamen that its gene expression is modulated by glucocorticoids, dopamine and glutamate. Here, we report for the first time, using quantitative in s...
