- Scientists Paint Multicolor Atlas of the Brain ()
Summary: A newly developed technique dubbed NeuroPAL is helping researchers investigate the dynamics of neural networks in the nervous system of microscopic worms. Source: Columbia University The human brain contains approximately 86 billion neurons, or nerve cells, woven together by an estimated 100 trillion connections, or synapses. Each cell has a role that helps us […]
- AI-Designed Serotonin Sensor May Help Scientists Study Sleep and Mental Health ()
Summary: Artificial intelligence technology redesigned a bacterial protein that helps researchers track serotonin in the brain in real-time. Source: NIH Serotonin is a neurochemical that plays a critical role in the way the brain controls our thoughts and feelings. For example, many antidepressants are designed to alter serotonin signals sent between neurons. In an article […]
- Schizophrenia is soon to be cured by injections of medicaments like Invega Trinza and it will open the way to other researches ()
Schizophrenia is soon to be cured by injections of medicaments like Invega Trinza and it will open the way to other researches like treating stupidity, to become more gentle (morality), to have higher intelligence or higher interest to work and having a better memory. Schizophrenia is a very heavy disease and is grabbing most of […]
- Even After Long-Term Exposure, Bionic Touch Does Not Remap the Brain ()
Summary: After a year of using a bionic arm, patients report subjective sensations did not shift to match the location of the touch sensor on their prosthetic device. Source: University of Chicago Advances in neuroscience and engineering have generated great hope for Luke Skywalker-like prosthetics: robotic devices that are almost indistinguishable from a human limb. […]
- How the Brain Distinguishes Speech From Noise ()
Summary: Study reports a pervasive neuromodulation system strongly influences sound processing in a key auditory region of the brain. Findings suggest acetylcholine may assist in the brain’s ability to distinguish speech from other noise. Source: Lehigh University For the first time, researchers have provided physiological evidence that a pervasive neuromodulation system – a group of […]
- Visual Illusion That May Help Explain Consciousness ()
A new visual illusion sheds light on redundancy masking and how we perceive our visual environment. The findings provide new insight into human consciousness. How much are you conscious of right now? Are you conscious of just the words in the centre of your visual field or all the words surrounding it? We tend to […]
- Scientists develop AI that can turn brain activity into text ()
Researchers in US tracked the neural data from people while they were speaking Reading minds has just come a step closer to reality: scientists have developed artificial intelligence that can turn brain activity into text. While the system currently works on neural patterns detected while someone is speaking aloud, experts say it could eventually aid […]
- Computers Generate Faces Based on Mental Maps ()
October 21, 2020 Cognitive neuroscientists have long debated about whether people have visual-like “pictures in the brain” that we activate when we think of them, or whether representations are more semantically organized in sets of features. So, for example, if asked to think of a blond person, will someone conjure in their “mind’s eye,” a […]
- Projects launch to map the nucleus, the information center of our cells ()
Through the NIH-funded 4D Nucleome program, new efforts are underway to model the nucleus in human stem cells and capture 3D genome organization in mouse and human brain cells New research is underway to better understand the nucleus, the control center of our cells. Teams from two divisions of the Allen Institute, the Allen Institute […]
- The mammalian brain is built from many kinds of neurons. A new study reveals a holistic way to look at them. ()
Using a technique that simultaneously captures different kinds of features from each cell, researchers lay groundwork for a “family tree” of the brain. A technique that captures information about a neuron’s 3D shape, electrical properties, and its genes is giving scientists a new way to look at cell types in the mouse brain and the […]
- These Scientists Just Completed a 3D ‘Google Earth’ for the Brain ()
Human brain maps are a dime a dozen these days. Maps that detail neurons in a certain region. Maps that draw out functional connections between those cells. Maps that dive deeper into gene expression. Or even meta-maps that combine all of the above. But have you ever wondered: how well do those maps represent my […]
- Human Brain Project launches ‘Google Earth’ of the brain ()
Scientists have developed an atlas of the brain which has the potential to improve research, treatment and surgery for conditions including epilepsy and cancer. As part of the new EBRAINS digital infrastructure of the European Human Brain Project, a team of scientists has developed a microstructure atlas of the brain. The atlas is said to […]
