Table 2. The effects of acute psychological stress on CB₁ receptor binding and signaling.

There was no effect of 30 min restraint stress on the maximal binding (B_max) or the binding affinity (K_d) of the CB₁ receptor, nor the maximal stimulation (E_max) or the EC50 of CB₁ receptor-mediated ³⁵S-GTPγS binding within the amygdala. Values denoted are means ± SEM. For all treatment conditions, n = 4.

	Basal	Stress
Amygdala
B_max (pmol/mg protein)	0.11 +/- 0.01	0.17 +/- 0.05
K_d (nM)	0.33 +/- 0.04	1.09 +/- 0.60
E_max (% baseline)	188.0 +/- 6.3	181.7 +/- 10.1
EC50 (nM)	81.0 +/- 8.5	127.6 +/- 22.5
