“The potential to create personalised digital 'twins' of your brain and body is a hot topic in neuroscience and medicine today.”
INSUFFICIENT EVIDENCE
No evidence found in cross-references, web search, or Wikipedia to confirm or refute the claim about digital brain/body twins being a hot topic.
“These computer models are designed to simulate how parts of your brain interact, and how the brain may respond to stimulation, disease or medication.”
INSUFFICIENT EVIDENCE
No evidence found in cross-references, web search, or Wikipedia to confirm or refute the claim about digital brain twin simulation capabilities.
“The extraordinary complexity of the brain’s billions of neurons makes this a very difficult task, of course, even in the era of AI and big data.”
INSUFFICIENT EVIDENCE
No evidence found in cross-references, web search, or Wikipedia to confirm or refute the claim about neuronal complexity challenges for digital twins.
“People’s brains are all wired slightly differently, so everyone has a unique network of neural connections that represents a kind of 'brain fingerprint'.”
INSUFFICIENT EVIDENCE
No evidence found in cross-references, web search, or Wikipedia to confirm or refute the claim about unique neural 'brain fingerprints'.
“However, most so-called brain twins are currently more like distant cousins. Their performance is barely any closer to the real thing than if the model were using the wiring diagram of a random stranger.”
INSUFFICIENT EVIDENCE
No evidence found in cross-references, web search, or Wikipedia to confirm or refute the claim about current brain twin accuracy limitations.
“Digital twins are increasingly proposed as tools for testing treatments by computer simulation, before applying them to real people.”
INSUFFICIENT EVIDENCE
No evidence found in cross-references, web search, or Wikipedia to confirm or refute the claim about digital twins as treatment testing tools.
“Our findings suggest that realistic digital brain twins require something that many existing models overlook: competition between the brain’s different systems.”
INSUFFICIENT EVIDENCE
No evidence found in cross-references, web search, or Wikipedia to confirm or refute the claim about competition between brain systems in digital twins.
“The human brain is never static. The ebb and flow of its activity can be mapped non-invasively using neuroimaging methods such as functional MRI.”
INSUFFICIENT EVIDENCE
No evidence found in cross-references, web search, or Wikipedia to confirm or refute the claim about non-invasive brain activity mapping.
“The brain is often described as a highly cooperative system. Yet everyday experiences such as focusing attention or switching between tasks tells us intuitively that brain systems compete for limited resources.”
INSUFFICIENT EVIDENCE
No evidence found in cross-references, web search, or Wikipedia to confirm or refute the claim about brain system competition during tasks.
“The vast majority of brain simulations over the past 20 years have not taken these competitive interactions between regions into account.”
INSUFFICIENT EVIDENCE
No evidence found in cross-references, web search, or Wikipedia to confirm or refute the claim about competitive interactions being overlooked in brain simulations.
“Our international team of researchers used non-invasive brain activity recordings to show that the most realistic whole-brain models not only require cooperative interactions within specialised brain circuits, but long-range competitive interactions between different circuits.”
PENDING
“In humans, monkeys and mice, the models that included competitive interactions consistently outperformed cooperative-only models.”
PENDING
“Using a large-scale analysis of over 14,000 neuroimaging studies, we found that spontaneous activity in the competitive models more faithfully reflected known cognitive circuits, such as those involved in attention or memory.”
PENDING
“Crucially, models with competitive interactions were not only more accurate but also more individual-specific.”
PENDING
“The fact that our findings hold across humans and other mammals suggests they reflect fundamental principles of how intelligent systems work.”
PENDING
“Combining brain imaging data from human patients with whole-brain modelling could radically change this. A framework that works across species would provide a powerful bridge between basic research and clinical application.”
PENDING
“If someone needs intervention in the brain, for example due to epilepsy or a tumour, their digital twin could be used to explore how the patient’s brain activity would change when stimulated with different levels of drugs or electrical impulses.”
PENDING
“The general principles of brain organisation across species also offer a path for understanding how to shape the next generation of artificial intelligence.”
