the fundamental principles of neuronal activity such as ( 1 ) the electrogenesis of gray matter , i.e. , the electric current and membrane potential aspects of the existence and the functioning of nerve cells and neuronal aggregates , ( 2 ) the rhythmicity and periodicity of nervous activity in single cells or networks of neurones , ( 3 ) the synchronization of such nervous activity due , at the site of its source , to electric interaction between neurones belonging together and 'beating in unison ' , and ( 4 ) the autonomous automaticity of nerve cells and nerve centres as being the basic feature of neuronal activity , are among the prominent topics dealt with in this report .
