In the presence of L-isoproterenol (through local infusion into area CA1), the theta-pulse stimulation with the parameter of 10 Hz, 150 pulses/train, 1 train, a frequency weakly modifying synaptic strength, induced a robust LTP, and this effect was blocked when DL-propranolol was co-administered. By contrast, the theta-pulse stimulation with the parameter of 5 Hz, 150 pulses/train, 3 train, a frequency strongly modifying synaptic strength, induced a significantly smaller LTP when DL-propranolol was administered into area CA1. Accordingly, DL-propranolol impaired rat's spatial learning in the water maze when infused into area CA1 20min pretraining.
