AUDIO: Anatomy of a Panic Attack

Occurring without warning, the panic attack is a crippling and cruel symptom of many anxiety disorders. These debilitating episodes thrust individuals into intense bouts of terror, leaving them fighting to regain control of their own body.

The piece combines interview material recorded with a friend and abrasive sound design to pull the listener into the experience of a panic attack. It was produced as part of the Hubbub Relaxation / Cacophony tape, commissioned by the Wellcome Trust and featured during the Lates Spectacular event in September 2015.

Video: This Film Sucks! – The Science of Leeches

Tim Cockerill returns to take a  look at some leeches in a short piece produced for YouTube’s Geek Week back in August. If you’re a bit squeamish this probably isn’t for you!

We couldn’t really make a video about leeches without showing off their impressive feeding apparatus, a Y-shaped jaw packing in roughly 300 teeth! This was a tricky shot to achieve, we had to persuade the leech to attach to a glass plate, holding it in position by hand, allowing us to shoot from below with a macro lens. It was a great sight to behold once we finally got it and it certainly helps bring something to the film that you hopefully wont have seen elsewhere.

We also had to get some footage of a leech feeding, so we set one loose on Tim’s arm, shooting a time-lapse to demonstrate how much they can expand during the feeding. Once it had attached to feed, we were very much at the mercy of the Leech’s hunger as we couldn’t shoot the final shots until it had detached. As Tim mentions in the film, it’s not a good idea to pull or burn leeches off as this may cause them to vomit their stomach contents back into the open wound – not a good idea if you don’t know what the leech as been feeding on previously. The best course of action to take is to let detach when it’s good and ready.

We also wanted to dispel a common myth about leeches using anaesthetics to dull the pain the sensation of pain whilst feeding – as Tim reports there’s little scientific evidence to support this and he certainly reports to feel a stinging sensation as the leech feeds on him.

After about 3 hours the leech was finally full and very happily detached from Tim’s arm – during ‘the feeding’ the leech utilises an anti-coagulant (called hirudin) and as you can see in the film this prevents the blood from clotting, causing the wound to bleed profusely four a couple of hours after it’s detached!

Why Does The Placebo Effect Work?

My latest film for The Ri Channel takes a look at the placebo effect and it’s central paradox – if we have the ability to cure our symptoms of illness when taking a placebo- why can’t we just do this all the time?

The film looks at the ‘WHY’ rather than the ‘HOW’ of the placebo effect and features Professor Nicholas Humphrey – an evolutionary psychologist who has contributed a significant amount of work to our understanding  of consciousness and the evolutionary context of the placebo effect.

I was aware of how the body is able to reduce pain through the use of it’s own internal painkillers (the endogenous opiates) – but I’d never really considered the evolutionary context of the placebo effect. WHY can’t we just deploy it whenever we want, why is it that a sugar pill can somehow grant us permission to do this and what information are we acting upon when we take placebo medications.

The film was created as part of a YouTube Super Collaboration (possibly the first in its kind) – which brought together 10 Science YouTube Channels each exploring 10 unanswered questions in science – the project was coordinated by the Channel AllTime10s – a monumental effort cajoling all ten channels into meeting the same deadline! You can view the AllTime10s video below, which links to all the videos in the collaboration:

Production notes

AllTime10s asked us to produce a video on the placebo effect and we had a very tight deadline for this film (about a month to conceive and produce!) – after a bit of mild panic and some research we were delighted to have Professor Humphrey on board – he was incredibly helpful in informing this project.

Due to limited time we decided to shoot this in the format of an interview and cut the audio together to present a logical argument. I think the most difficult aspect in producing this film was in conveying the information succinctly, in the right order and deciding what to leave out. Obviously there was a lot of nuance and detail that we simply couldn’t afford to go into – so there was a lot of careful consideration involved in presenting these arguments concisely to a YouTube audience. As it often goes with the editing process – there were some painful moments  having to excise sections from the film.

Professor Humphrey had a number of thought experiments to help illustrate his arguments and I was keen to use these within the film, as they help to add real-world context from which to grasp these ideas. One of these was an anecdote of a schoolboy falling over in the playground and experiencing pain – with this section I was particularly conscious that we needed some sort of visual aid to augment the story.

At first I started with simple static slides created in Key Note, but found myself longing for something more dynamic. These slides then became placeholders and I later revamped them in Motion. This was true for the rest of the film as well, we were dealing with a lot of talking-head footage and I wanted to add in some motion graphics to help break this up and provide moments of pause between sections. I must say I’m completely new to using Motion and animation – so they are simplistic, but it was a great way of teaching myself how to do these things.

The style of these animations was very much guided by the central anecdote in the film (the schoolboy story) and this is why we see a chalkboard, wobbly text (it’s not Comic Sans!), simplistic stick men (I’m also a bit crap at graphics) and playful music.

I also really like the opening titles – although I’ll admit they’re not entirely keeping with the rest of the film’s style.

The film was shot with a Panasonic AF101, Nikon D7100 and edited on FCPX.
