Supramolecular polymers can dramatically enhance brain cell activity

Supramolecular polymers can dramatically enhance brain cell activity

Biomedicine • Chemistry • Materials • Neuroscience

By Mapping Ignorance

Scientists have developed remarkably long, precisely patterned molecular threads that could open new possibilities for designing advanced materials. The scientists also discovered these threads — called supramolecular polymers — can dramatically enhance brain cell activity. Built from self-assembling molecules, the longest threads reach dimensions greater than the diameter of a cell. By molecular standards, they […]

Authors: Elisa Rigosi, Researcher in Sensory Biology, Department of Biology, Lund University and David O’Carroll, Professor of Sensory Biology, Department of Biology, Lund University One bee has long been regarded as a benchmark for visual performance: the honeybee drone. These male honeybees (Apis mellifera) have evolved highly specialised eyes for detecting queens during mating flights […]

What we actually see – and don’t see – tells us a lot about consciousness

What we actually see – and don’t see – tells us a lot about consciousness

Neuroscience • Philosophy of science

By Invited Researcher

Author: Henry Taylor, Associate Professor, Department of Philosophy, University of Birmingham What can you see right now? This might seem like a silly question, but what enters your consciousness is not the whole story when it comes to vision. A great deal of visual processing in the brain goes on well below our conscious awareness […]

Modeling the brain’s solution to the cocktail party problem

Modeling the brain’s solution to the cocktail party problem

Neuroscience

By Mapping Ignorance

MIT neuroscientists have figured out how the brain is able to focus on a single voice among a cacophony of many voices, shedding light on a longstanding neuroscientific phenomenon known as the “cocktail party problem.” This attentional focus becomes necessary when you’re in any crowded environment, such as a cocktail party, with many conversations going […]

First living cochlea outside the body unlocks secrets of hearing

First living cochlea outside the body unlocks secrets of hearing

Biomedicine • Medicine • Neuroscience

By Rosa García-Verdugo

Have you ever wondered how your ears can pick up the faintest whisper yet also handle loud music without damage? Scientists at Rockefeller University have achieved a remarkable feat : they kept a tiny piece of cochlea alive and working outside the body, allowing them to witness the hearing process in unprecedented detail. Building a […]

Dynamic diversity of astrocytes charted in new atlas

Dynamic diversity of astrocytes charted in new atlas

Neurobiology • Neuroscience

By Mapping Ignorance

When it comes to brain function, neurons get a lot of the glory. But healthy brains depend on the cooperation of many kinds of cells. The most abundant of the brain’s non-neuronal cells are astrocytes, star-shaped cells with a lot of responsibilities. Astrocytes help shape neural circuits, participate in information processing, and provide nutrient and […]

Major theories of consciousness may have been focusing on the wrong part of the brain

Major theories of consciousness may have been focusing on the wrong part of the brain

Neuroscience

By Invited Researcher

What gives rise to human consciousness? Are some parts of the brain more important than others? Scientists began tackling these questions in more depth about 35 years ago. Researchers have made progress, but the mystery of consciousness remains very much alive. In a recently published article, I reviewed over 100 years of neuroscience research to […]

Specific brain cells enable intelligent behaviour

Specific brain cells enable intelligent behaviour

Neuroscience

By Invited Researcher

Author: Mohamady El-Gaby, Postdoctoral Neuroscientist, University of Oxford For decades, neuroscientists have developed mathematical frameworks to explain how brain activity drives behaviour in predictable, repetitive scenarios, such as while playing a game. These algorithms have not only described brain cell activity with remarkable precision but also helped develop artificial intelligence with superhuman achievements in specific […]
