Researchers at Weill Cornell Medicine and Birkbeck, University of London, have identified a site where a commonly used anesthetic binds to sodium ion channels, revealing a molecular mechanism that may explain how these drugs dampen communication between neurons. Ion channels are

Researchers at the University of Tsukuba have identified small nuclear fragments known as micronuclei while studying neurons in aged mice. They demonstrated that microglia—the brain's resident immune cells—take up these micronuclei, leading to changes in microglial morphology and

Eles podem penetrar no cérebro - e atrapalhar a comunicação entre os neurônios. O recorte ajuda a contextualizar a pauta dentro de Ciência.

Chris Johnson, a former running back with the Tennessee Titans, New York Jets and Arizona Cardinals, has revealed he has been diagnosed with Motor Neurone Disease/Amyotrophic Lateral Sclerosis.

Former South Sydney Rabbitohs and Queensland player Jai Arrow, who announced his retirement earlier this year after being diagnosed with Motor Neurone Disease (MND), carries out the State of Origin shield.

Scientists have discovered a tiny group of neurons in an ancient brain region that acts like a built-in focus filter, helping the brain ignore distractions and zero in on what matters most. When researchers temporarily switched off these neurons in mice, the animals became unusua

Living cells constantly exchange ions (i.e., charged particles) via the thin barrier that surrounds their interior, known as the outer membrane. Neuroscientists and medical researchers have long been trying to devise effective methods to measure this exchange of ions, which is kn

McGill University researchers have developed a light-detecting nanoscale structure that mimics how a neuron processes information. The neuron-like behavior emerges from the materials themselves, reducing the energy demand associated with similar devices that rely on circuits or s

A common brain protein may be giving Alzheimer’s disease an unexpected way to spread, carrying toxic Tau proteins from damaged neurons into healthy ones. By blocking these harmful protein packages before they reach new cells, researchers believe it may one day be possible to slow

Researchers have identified a previously overlooked mechanism of brain cell death that appears to play a major role in Alzheimer's disease and frontotemporal dementia. The finding could lead to new treatments aimed at slowing neuron loss by interrupting the process before cells a

Yale scientists discovered two neuron surface proteins that appear to help spread the toxic protein linked to Parkinson’s disease. Blocking these proteins in mice dramatically reduced disease progression, offering a potential new target for future therapies.

Pesquisadores da Universidade de Nankai, na China, desenvolveram um "ouvido biônico" que promete criar uma ligação direta entre um sistema artificial e o sistema nervoso para combater a perda auditiva neurossensorial. O dispositivo, apresentado na revista científica Nature Materials, funciona como uma interface neuromórfica capaz de reproduzir funções do nervo auditivo. Ao detectar sons, interpreta antes de enviá-los ao c&eacu
