Filling length measures the length of the contracting closed loops in a null-homotopy. The filling length function of Gromov for a finitely presented group measures the filling length as a function of length of edge-loops in the Cayley 2-complex. We give a bound on the filling length function in terms of the log of an isoperimetric function multiplied by a(More)
Two patients, aged 23 and 74 years, manifested prolonged episodes of mildly impaired consciousness in conjunction with rhythmical spike waves or spikes (mostly 3/s). This paroxysmal EEG activity was consistently accentuated unilaterally over the superior frontal regions. The first patient showed ictal aphasia and occasional right hemiparesis during these(More)
Myoclonus is a phenomenon which cuts through a considerable number of neurological conditions. It occurs in a variety of epileptic conditions (Primary generalized epilepsy, hypsarrhythmia, Lennox-Gastaut syndrome, also known as "petit mal variant"), in inborn errors of metabolism (Tay-Sachs disease, forms of ceroid lipofuscinosis), in neurobiochemically(More)
