Why You Remember Emotional Events Better than Non-emotional Ones

Most people remember emotional events vividly, such as their wedding day, but researchers are unsure how the human brain prioritizes emotional events in memory. In a new study, Joshua Jacobs, an associate professor of biomedical engineering at Columbia Engineering, and his colleagues found that the human brain has a specific neural mechanism that tags information…

How Vestibular Synapses Are Specialized for Speedy Transmission

Specialized synapses in our sensory organs enable us to walk, dance, and turn our heads without experiencing vertigo or losing our balance. These synapses process signals more quickly than any other parts of the human body. A small group of neuroscientists, physicists, and engineers from different institutions has now figured out how these synapses work. This…

Managing Negative Emotions Better Could Help Limit Neurodegeneration

Dementia and neurodegenerative diseases are thought to be accelerated by negative emotions, such as anxiety and depression. But how do they affect the brain? Could be it possible to limit their negative effects? Neuroscientists at the University of Geneva (UNIGE) observed the activation of the brains of young and old adults when confronted with the…

Astrocytes Play Key Role in Spatial Learning Control

Glial cells insulate nerve cell “wiring” or provide optimal working conditions for them. A new study led by the University of Bonn has discovered another function in rodents: the findings suggest that a specific type of glial cell is important in spatial learning. Each place in our world has its own unique features that make…

Late-onset Cerebellar Ataxia Genetic Cause Identified

Researchers have identified a previously unknown genetic cause of late-onset cerebellar ataxia. The finding will help with diagnosis and open up new treatment options for this progressive disease. Late-onset cerebellar ataxias (LOCA) are a diverse group of neurodegenerative diseases that cause unsteadiness in adults. Cerebellar ataxia is a type of ataxia that begins in the…

Recently Found Brain Part Serves As Guardian Layer

Researchers have found a previously unidentified area of brain anatomy that serves as a barrier of defense and a base from which immune cells watch the brain for inflammation and infection. The human brain only reluctantly divulges its secrets, including the intricate nature of neural networks and fundamental biological processes and structures. Only recently have developments…

A Neurofunctional Schema for Dimensions of Consciousness

There is more to the question of what consciousness is than just philosophy. Researchers are still just beginning to explore how the human brain’s electrochemical activity is able to give rise to conscious experience. Recent research suggests that consciousness is caused by a network of neurons rather than a single location in the brain. On…

Newly Found Olfactory Nerve Cell Organelle Has Role In Smell Perception

Researchers in Sweden have found an organelle, a previously unidentified cellular component, inside the neurons responsible for our ability to smell. The finding might have repercussions for future studies on COVID-19 symptoms like impaired smell sense. The cellular component called an organelle that the researchers have found inside nerve cells is something that has never…
