Evoked EEG alpha oscillations in the cat brain--a correlate of primary sensory processing?

abstract：:Iontophoretically applied 2-azido photoaffinity analogues of adenosine 5'-triphosphate (ATP) and adenosine 5'-monophosphate (AMP) have been tested on rat cerebral cortical neurons. 2-Azido-AMP and 2-azido-ATP had a powerful depressant action on the spontaneous firing of cortical neurons. Both compounds were equipotent...
