Electrically induced LTP of mossy fiber synapses is not affected by application of a β-adrenergic receptor antagonist. (A) HFS (four trains of 100 pulses given at 100 Hz) elicits LTP. Injection of the β-adrenergic receptor antagonist, propranolol (2 μg), did not change the profile of the LTP elicited. Line breaks indicate changes in time scale. (B) Analog traces represent recordings taken (i) 5 min pre-LFS, (ii) 5 min post-HFS, and (iii) 24 h in the presence of vehicle (left panel), or propranolol (right panel). Vertical scale bar: 2 mV, horizontal scale bar: 6 ms.
