Pseudo-seizure vii -2010

This is my second submission to sound lab and due to the 10th anniversary I decided to share my most recent piece which belongs to a series called pseudo-seizures with aura. Pseudo-Seizure7 was conceivedafter a 3 month placement at a

Hospital’s Neurology Ward. I exploredthe aesthetics of auras during the preamble to an epileptic seizure by interviewing 2 selected epileptic patients who experience recurrent auditory auras (hallucinations) during status epileptics. I generated an extensive series of soundsamples based on these patients’ descriptions. The 2 patients then listened and ranked these sound samples in terms of their resemblance to their auditory aural experiences. To my surprise the samples that ranked more highly came from harsh textures generated by one of my vector synthetiser (TG33 partly designed by Dave Smith for Yamaha back on the days …). With this insight I then generated 11 sound-scapes of which number 7 is the current submission. In addition to these ‘synthetic epileptic auras’ there is a dodecaphonic percussive line which is a mapping of 12 relevant ‘electric events’ extracted from epileptic electro encephalograms (EEGs). The mapping is so that a 12 note system maps epileptic markers and the rhythm is a direct temporal map of when these epileptic events happened – in real time.


To conclude, the following is a prosaic deconstruction of the physiopathology associated with temporo-parietal seizures with aura. In my opinion a knowledge of this biology is fundamental so to empathise with epileptic patients. I highly recommend reading this some-how-non-sense-paragraph before listening … enjoy the music.

“auras – from – 80% of temporal lobe seizures + common feature — simple partial seizures +++ precede complex partial seizures of temporal lobe origin -~ “auditory hallucinations” :: ‘buzzing’ sound – ‘voice or voices’ or muffling or ambient or harsh sounds. ?neocortical temporal lobe epilepsy vs ?other types of temporal lobe epilepsy. ->Following the aura, a temporal lobe complex partial seizure begins ->> wide-eyed ->>> motionless stare ->>>> dilated pupils ->>>>> behavioral arrest, ‘oral alimentary automatisms’ ‘lip smacking + chewing. Manual automatisms too. or unilateral dystonic posturing of my limbs – could be one or more. most auras and automatisms last a very short period—seconds or 1-2 minutes. The postictal phase may last for a longer period (several minutes, perhaps 14.21 minutes). By definition, amnesia occurs during a complex partial seizure because of bilateral hemispheric involvement – so –
