by Samantha Rey06 December 2024 view large AI pinpoints stroke timing, treatment potential from a single scan New AI software can read the brain scans of patients who have had a stroke, to more accurately pinpoint when it happened and help doctors work out whether it can be successfully treated. It is hoped that the new...

Neuroscientists discover a new pathway to forming long-term memories in the brain
by Max Planck Florida Institute for Neuroscience Scientists discover a new pathway to long-term memory formation in the brain that can bypass the formation of short-term memory. Credit: Helena Pinheiro Researchers from Max Planck Florida Institute for Neuroscience have discovered a new pathway to forming long-term memories in the brain. Their work, published in Nature Neuroscience, suggests that long-term...

Primate study sheds light on a neural mechanism that separates signal from noise in the brain
by University of Tokyo Mesoscale functional imaging revealed patchy spatial patterns of spontaneous activity throughout the marmoset neocortex. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-54322-x When the brain is observed through imaging, there is a lot of “noise,” which is spontaneous electrical activity that comes from a resting brain. This appears to be different from brain activity that comes...

Researchers identify new therapeutic approach to preventing cancer from spreading to the brain
October 1, 2024 by McMaster University In a study published in the journal Cell Reports Medicine, researchers Sheila Singh and Jakob Magolan discovered a critical vulnerability in metastatic brain cancer, which they say can be exploited with new drugs to prevent spread. Singh, a professor in McMaster’s Department of Surgery and director of the Center...

Neuroplasticity: Rewiring the Brain
By Marzia KhanReviewed by Danielle Ellis, B.Sc. Understanding neuroplasticityNeuroplasticity, or brain plasticity, can be defined as the ability of the nervous system to alter its activity in response to a stimulus by reorganizing its structure, function, and neuronal connections. The history of plasticity can be traced to William James in 1890, with the first mention...

Hallucinations from flickering lights: what happens in our brain?
News Release 10-Sep-2024 Peer-Reviewed PublicationNetherlands Institute for Neuroscience – KNAW image: Infographic hallucinations Credit: Eline Feenstra – Netherlands Institute for Neuroscience A new study from the Netherlands Institute for Neuroscience shows how flickering light can cause hallucinations in our brain: it produces ‘standing waves’ of brain activity. You’re sitting on the bus or train and...

Cough or sneeze? How the brain knows what to unleash
06 September 2024 ‘Sneeze neurons’ activated by triggers such as pollen or a viral infection send an achoo signal, whereas cough neurons induce a hack. The cough triggered by pollen and other allergens is activated by neurons distinct from those that lead to a sneeze.Credit: Getty Does a whiff of pollen trigger a sneeze or...

New study reveals the signals in your brain that initiate spontaneous actions
September 5, 2024 by Chapman University Credit: Unsplash/CC0 Public DomainA new study published in Nature Communications examines how the brain initiates spontaneous actions. In addition to demonstrating how spontaneous action emerges without environmental input, this research has implications for the origins of slow ramping of neural activity before movement onset—a commonly-observed but poorly understood phenomenon....
