This weekend our Sonic Tour of the Brain will make its debut performance at the Barbican, part of the Brain Waves Weekender!
You can listen to download, and (we hope) enjoy the auditory tour of the mind here.
If you are enjoying this tour in the heart of the Barbican Mezzanine – lucky you! We hope you are basking in the glow of our wonderful brain, constructed by Bristolian model maker Roseanne Wakely.
In this 20 minute audio tour, we explore the question… what does the brain sound like? Most people can imagine what the brain looks like, feels like, and maybe even smells like – but few might have ever thought about what it sounds like.
We have chosen a dozen different recordings, each of which illustrates a different aspect of how the brain works, and how we try to understand it.
1. Surgical Saw: This is the real sound of a brain being sliced open with a piece of cheese wire at a hospital in the Ukraine. Many thanks to Geoffrey Smith, director of The English Surgeon, and Angela Saward, Curator of Moving Image & Sound at the Wellcome Library, for providing this track.
2. Wobbling Jelly: This is not the sound of a real brain, but of a block of jelly, which food artisans Bompas & Parr, in association with sound artist Douglas Murphy made in a soundproof studio. This is what a real brain would sound like, as it has the consistency and texture of jelly.
3. Epileptic Seizure – This is the sonified version of an EEG, recorded in the 1960s. The patient in question was a small child in the 1960s (name withheld for privacy reasons). Many thanks to our benefactors The Wellcome Trust for providing us with this original piece of historical material.
4. Auditory Nerve – This is a single cell nerve recording, taken using a glass needle, stuck into the auditory nerve of a hamster in the 1960s.
5. Cochlear Implant – This is not the real sound of a cochlear implant, but a simulation of what one may sound like to its users.
6. Mosquito Frequency – All of us will lose our ability to hear tones of higher frequencies as we age, due to the thickening of the basilar membrane, the bedrock of the cochlear spiral. Ain’t that but a crying shame. The sound of 17,000Hz will be heard by only the younger audience members. Can you hear it? Editor’s note: We promise that it’s not a fake.
7. Neverending Scale – The Shepard Scale is often compared to an Escher staircase - and even those of us who have heard it over and over find the concept difficult to understand, let alone explain in clear language. The best source I have found online that explains the nature of this illusion is this clip from Bang Goes The Theory.
8. Shepard-Risset Glissando – A variation on the Shepard Scale, but as a glissando. Creepy stuff! Try listening to it over and over and over – we promise it never stops feeling weird. If you look at this youtube clip, which visualises the sound waves, it might make a bit more sense.
9. Binaural Illusion – Our brains use the tiny time differences between sounds reaching our right and left ears to calculate the source of the sound in physical space. Enjoy.
10. Phantom Words – These come from Prof Diana Deutsch of the University of California, who is the master of sonic illusions – some have called her the grand dame of auditory neuroscience. She is one cool cat – and a fantastic example of a scientist who is not only a woman, but also achieves things that are, for lack of a better descriptor, spectacularly original. They can find all the examples of her work online for free on her website.
11. Reconstructed Speech – Dr Brian Pasley is using sophisticated software and intracranial recordings of the brain to reconstruct what words subjects heard, and to reproduce them with computer algorithms. You can read the original paper in PLoS Biology here.
12. Music of the Hemispheres – Prof Dan Lloyd has translated the activity of fMRI recordings of the brain into music – you can watch this video and read more about his work here. Honestly – his theory is really without any rivals, artistically or philosophically. Whether you agree with his hypothesis – that “we are all symphonies” or not – you will at least find the videos and short films edifying.
13. Remix: The Music Of The Mind – An original remix created for us by composer Dean Williams – made entirely from the sound samples from the rest of this tour. You can download that entire track and learn more about how he made this unprecedented musical score here.
This has been the Guerilla Science Sonic Tour of the Brain – we perhaps might not have been able to explain exactly what the brain sounds like, but we hope, there are many different ways of approaching the question.

Zoe will be speaking about the her favourite subject – the origins of music – at Superstripe, the first in a series of exhibitions hosted at Pattern Power!
The Evolution of Music
Making music is one of the weirdest things we do, and yet every culture does it. Why? Neuroscience has revealed that music affects the brain like nothing else, prompting synchronized symphonies of electrical pulses. More than mere entertainment, science hints at a primal place for organized sound.
When: Tuesday April 16th, 7pm
Where: Pattern Power, 28 Redchurch St Shoreditch, London
Pattern Power is the first in a series of annual exhibitions and events hosted by Patternity that will explore the powerful presence of pattern and it’s ability to positively connect us all. Taking over the Londonewcastle Project Space - 28 Redchurch Street in East London E2 7DP - London design collective Patternity will immerse visitors into an intriguing and tactile world of stripes as we transport our ethos of ‘celebrating pattern everywhere’ offline and into the real world.

In partnership with the Zoological Society of London and Selfridges department store, we will be hosting a variety of workshops, performances and demonstrations every Saturday from May 14 to June 4 as part of Project Ocean, a month of activities involving more than 20 environmental and conservation groups aimed at tackling over-fishing and raising funds to establish new Marine Reserves with the ZSL in the Philippines.
Come find us every Saturday in the Ultralounge inside Selfridges on Oxford Street in London as we explore the complexity, fragility and beauty of the sublime seas of the world.

“Some of you may have come to the festival to have the sex, drugs and rock n’ roll, and I’d like to talk a bit about what might be happening in your brain when you do those things.”
“Does anybody here like music? That’s an easy question.”
“Not every society has writing or agriculture – but every single one on the face of the earth has music.”
“Music can bring you into an altered reality where you lose track of time, track of sense, and gain that real emotional connection to the task you are carrying out.”
“We all have endorphins and adrenaline running through our bodies right now – you’re smiling so you must be feeling good.”
Featuring Jessica Grahn, Mortem Kringelbach, Gianna Cassidy, Zoe Cormier, Richard Bowdler, Jenny Wong, Adrian Owen, the Beatbox Laboratory, and Accelerated Learning with MC Inja.
Recorded at Latitude and the Secret Garden Party in July 2009 by Tom Mustill.
