Evidence is building that insects, octopus and other invertebrates feel emotions

Evidence is building that insects, octopus and other invertebrates feel emotions

ABC News (AU) reports: Up until the mid-1980s, human babies didn’t feel pain. Of course that’s not actually true, but due to research conducted in the 18th and early 19th centuries, it was an attitude that still lingered among a small minority of scientists and medical professionals. So much so that some infant surgery was still conducted without, or with very little, anaesthesia in the US into the ’80s. Today, the question of physical and emotional experience has moved beyond…

The man rethinking the definition of reality

The man rethinking the definition of reality

Tom Chatfield writes: If you woke up one day and discovered that you were living in a virtual world – that everything you’d ever known was, like the Matrix, a form of hyper-realistic simulation – what would this imply for your hopes, dreams and experiences? Would it reveal them all to be lies: deceptions devoid of authenticity? For most people, the intuitive answer to all these questions is “yes”. After all, the Matrix movies depict a dystopian nightmare in which…

I feel, therefore I am

I feel, therefore I am

Antonio Damasio writes: In the beginning was not the word; that much is clear. Life sailed forth without words or thoughts, without feelings or reasons, devoid of minds or consciousness. Not that the universe of the living was ever simple, quite the contrary. It was complex from its inception, four billion years ago. But living organisms then took several paths. In the branch of life history that led to us, I like to imagine three distinct and consecutive evolutionary stages….

Your attention didn’t whither away. It was stolen

Your attention didn’t whither away. It was stolen

Johann Hari writes: I went to Portland, Oregon, to interview Prof Joel Nigg, who is one of the leading experts in the world on children’s attention problems, and he told me we need to ask if we are now developing “an attentional pathogenic culture” – an environment in which sustained and deep focus is harder for all of us. When I asked him what he would do if he was in charge of our culture and he actually wanted to…

Can lab-grown brain organoids be ‘conscious’? Scientists may soon find out

Can lab-grown brain organoids be ‘conscious’? Scientists may soon find out

Anil Seth writes: In 2022 we will see brain organoids displaying dynamics that bear comparison with the complex activity patterns indicative of consciousness in humans. This will require us to rethink what counts as a brain signature of “consciousness” and will raise serious ethical issues about brainlike structures grown in the lab. Brain organoids are tiny, lab-grown bundles of neurons, derived from human stem cells, that display various properties of the developing human brain. In medicine, they provide much-needed biological…

The brain has a team of conductors orchestrating consciousness

The brain has a team of conductors orchestrating consciousness

Morten L Kringelbach writes: The execution of any musical symphony is a difficult task, demanding significant skills from each musician. Perhaps the hardest task lies with the conductor who must orchestrate the musicians so the music comes alive cohesively and speaks to our deepest emotions. The human brain is like an orchestra: different regions perform different types of processing, much like the individual musicians who must read the music, play their instruments, and also listen and adapt to the sounds…

Having a concept of death is far from being a uniquely human attribute

Having a concept of death is far from being a uniquely human attribute

Susana Monsó writes: Humans have long thought of themselves as the only animal with a notion of mortality. Our concept of death is one of those characteristics, like culture, rationality, language or morality, that have traditionally been taken as definitional of the human species – setting us apart from the natural world and justifying our boundless use and exploitation of it. However, as I have argued elsewhere, the widespread notion that only humans can understand death stems from an overly…

On the evidence for fungal intelligence

On the evidence for fungal intelligence

Nicholas P Money writes: Mushrooms and other kinds of fungi are often associated with witchcraft and are the subjects of longstanding superstitions. Witches dance inside fairy rings of mushrooms according to German folklore, while a French fable warns that anyone foolish enough to step inside these ‘sorcerer’s rings’ will be cursed by enormous toads with bulging eyes. These impressions come from the poisonous and psychoactive peculiarities of some species, as well as the overnight appearance of toadstool ring-formations. Given the…

The easy part of the hard problem of consciousness

The easy part of the hard problem of consciousness

Tam Hunt writes: How does consciousness arise? What might its relationship to matter be? And why are some things conscious while others apparently aren’t? These sorts of questions, taken together, make up what’s called the “hard problem” of consciousness, coined some years ago by the philosopher David Chalmers. There is no widely accepted solution to this. But, fortunately, we can break the problem down: If we can tackle what you might call the easy part of the hard problem, then…

Why walking helps us think

Why walking helps us think

Ferris Jabr writes: In Vogue’s 1969 Christmas issue, Vladimir Nabokov offered some advice for teaching James Joyce’s “Ulysses”: “Instead of perpetuating the pretentious nonsense of Homeric, chromatic, and visceral chapter headings, instructors should prepare maps of Dublin with Bloom’s and Stephen’s intertwining itineraries clearly traced.” He drew a charming one himself. Several decades later, a Boston College English professor named Joseph Nugent and his colleagues put together an annotated Google map that shadows Stephen Dedalus and Leopold Bloom step by…

The origin of consciousness

The origin of consciousness

Simona Ginsburg and Eva Jablonka write: MuZero is an algorithm with a superhuman ability to learn: it has learned to play 57 different Atari video games as well as Chess, Go and Shogi, and defeated the greatest human masters in every one of them. Yet, this amazing algorithm and the computer in which it is implemented are as conscious as your washing machine. Its “intelligence”, manifest in its learning ability, has nothing to do with consciousness – the ability to…

When did humans start experimenting with psychoactive drugs?

When did humans start experimenting with psychoactive drugs?

Nicholas Longrich, Author provided By Nicholas R. Longrich, University of Bath Humans constantly alter the world. We fire fields, turn forests into farms, and breed plants and animals. But humans don’t just reshape our external world – we engineer our internal worlds, and reshape our minds. One way we do this is by upgrading our mental “software”, so to speak, with myths, religion, philosophy and psychology. The other is to change our mental hardware – our brains. And we do…

Can consciousness be explained by quantum physics?

Can consciousness be explained by quantum physics?

Some scientists believe consciousness is generated by quantum processes, but the theory is yet to be empirically tested. vitstudio/Shutterstock By Cristiane de Morais Smith, Utrecht University One of the most important open questions in science is how our consciousness is established. In the 1990s, long before winning the 2020 Nobel Prize in Physics for his prediction of black holes, physicist Roger Penrose teamed up with anaesthesiologist Stuart Hameroff to propose an ambitious answer. They claimed that the brain’s neuronal system…

To be fully human we must also be fully embodied animal

To be fully human we must also be fully embodied animal

Melanie Challenger writes: When I visited my grandmother at the undertakers, an hour or so before her funeral, I was struck by how different death is from sleep. A sleeping individual shimmers with fractional movements. The dead seem to rest in paused animation, so still they look smaller than in life. It’s almost impossible not to feel as if something very like the soul is no longer present. Yet my grandmother had also died with Alzheimer’s. Even in life, something…

Does consciousness come from the brain’s electromagnetic field?

Does consciousness come from the brain’s electromagnetic field?

Johnjoe McFadden writes: Some 2,700 years ago in the ancient city of Sam’al, in what is now modern Turkey, an elderly servant of the king sits in a corner of his house and contemplates the nature of his soul. His name is Katumuwa. He stares at a basalt stele made for him, featuring his own graven portrait together with an inscription in ancient Aramaic. It instructs his family, when he dies, to celebrate ‘a feast at this chamber: a bull…

The voice in your head

The voice in your head

Sophie McBain writes: Patsy Hage began hearing voices when she was eight years old. She was playing with her brother in the attic when her scarf caught alight on a candle. She would always remember running downstairs to her mother, her clothing on fire, convinced she was going to die. She was rushed to hospital and treated for serious burns. It was in hospital that the voices first started talking to her. She heard them for the rest of her…
