“Open your mind”, “Expand your consciousness with Psychedlics”…we’ve all heard the buzz words which can seem pretty nebulous at times -so what does it mean exactly? Can mushrooms actually expand your consciousness? Can they allow us to feel and regard things in a grander, more meaningful way? If so, can this be proven or measured?
In our own search to answer these questions we came across this helpful article by British researcher, Robin Carhart-Harris, originally published on The Conversation. And apparently it can…
Psychedelic drugs and consciousness
Psychedelic drugs alter consciousness in a profound and novel way that increases the breadth and fluency of cognition. However, until recently, we were unable to offer an explanation for how the brain was altered to account for these effects.
In a new study, published in Human Brain Mapping, we scanned the brains of volunteers who had been injected with psilocybin – the chemical found in magic mushrooms which gives a psychedelic experience – and a control group who hadn’t, and discovered two key things: that psilocybin increased the amplitude (or “volume”) of activity in regions of the brain that are reliably activated during dream sleep and form part of the brain’s ancient emotion system; and that psychedelics facilitate a state of “expanded” consciousness – meaning that the breath of associations made by the brain and the ease by which they are visited is enhanced under the drugs.
Ego and emotion
This finding of a similar pattern to dream activity is intriguing. While the psychedelic state has been previously compared with dreaming, the opposite effect has been observed in the brain network from which we get our sense of “self” (called the default-mode network or ego-system). Put simply, while activity became “louder” in the emotion system, it became more disjointed and so “quieter” in the ego system.
Evidence from this study, and also preliminary data from an ongoing brain imaging study with LSD, appear to support the principle that the psychedelic state rests on disorganised activity in the ego system permitting disinhibited activity in the emotion system. And such an effect may explain why psychedelics have been considered useful facilitators of certain forms of psychotherapy.
We also looked at the range of connectivity configurations – or “motifs” – in the emotion system and found that a broader range of motifs emerged under psilocybin, and this effect began with the onset of the drug’s psychological effects.
This is an entirely novel analysis and its validity needs to be further tested – but it may offer an initial insight into the biological basis of the often described consciousness-expansion that is one of the hallmarks of a psychedelic experience.
Building a picture
Our research into the brain effects of psychedelic drugs began at the University of Bristol in 2009 and continues today at Imperial College London and Cardiff University.
We were interested in the idea that psychedelics facilitate communication across the brain and, more specifically, how the default-mode network in the brain, arguably science’s best biological correlate of the self, normally works to constrain this.
Our first study, published in Proceedings of the National Academy of Sciences in 2012, revealed decreases in brain activity after injection of psilocybin that were localised to the default-mode network.
This finding was exciting because it synched with the idea that psychedelics cause temporary “ego dissolution”, in other words – diminishing one’s sense of having a firm and enduring personality. Our new research adds to our understanding about how this happens.
Understanding the brain mechanisms that underlie enhanced cognitive fluency under psychedelics may offer insights into how these drugs may be psychologically useful, for example in helping patients experience an emotional release in psychotherapy, and also potentially enhancing creative thinking.
