we have previously shown that adenosine analogs depress hippocampal-evoked responses ( fepsps ) in a brain slice preparation , and in the present study , we observed that local pressure ejection of adenosine or r-phenylisopropyladenosine ( r-pia ) also reduced the fepsp recorded in situ in a theophylline-reversible manner .
