these functional properties have been characterized in part by new methods of neuronal circuit analysis , more specific methods of neuronal cytochemistry , and by extensive exploitation of more classical electrophysiological methodologies for the assessment of synaptic transmitter identification and mechanism , the results of experiments at the cellular level have permitted additional studies to be done on the possible behavioral significance of the events regulated by monamines in the awake animal , when the cytochemical and electrophysiological and behavioral exeriments are considered as connected aspects of the same brain sub-systems , then the simple electrophysiological concepts of excitation and inhibition seem inadequate to explain the integrative , amplifying and biochemical actions which can be performed by experimental manipulation of central monamine pathways .
