New Study Finds Axons May Resemble 'Strings of Beads' Instead of Smooth Lines
A recent study challenges the traditional view of axons as smooth, cylindrical fibres, revealing they may actually resemble "strings of beads" or nanoscopic varicosities. Conducted by researchers at Johns Hopkins University using a high-pressure freezing imaging method, the discovery showed rotund blobs connected by thin tubes within axons. These s...

Memories Are Not Limited to Brain, New Study Claims
A study from NYU reveals that kidney and nerve cells can perform memory-like functions, suggesting memory capabilities are not restricted to the brain. By replicating a spaced learning process, scientists observed memory gene activation in these non-neural cells, expanding possibilities for enhancing learning and treating memory-related health issu...

Research Shows What Happens to Your Brain When You Watch a Movie
Neuroscientists have mapped brain activity in people watching movies, showing how different networks respond to scenes involving people, objects, and action. Complex scenes activated brain regions linked to executive functions like problem-solving, while simpler dialogues primarily engaged language processing areas. The study, based on data from th...

Researchers Identify Amygdala Cell Clusters To Treat Anxiety and Depression
A recent study by UC Davis researchers has unveiled specific cell clusters in the amygdala that could provide insights into treating anxiety and depression. By examining these cell types in both humans and non-human primates, the research opens pathways for targeted therapies. Notably, FOXP2-expressing cells could serve as vital targets for new dru...

Researchers Create Innovative 3D Maps to Understand Octopus Arm Systems
Researchers at San Francisco State University have developed advanced three-dimensional maps of octopus arms, revealing their complex nervous systems. Led by Robyn Crook, the team used innovative imaging techniques to understand how octopus arms can function almost independently from the brain. These discoveries highlight the unique neuronal organi...

Novel Brain-Computer Interface Improves Control of Prosthetic Hands With Thought Alone
A recent study by scientists at the German Primate Center has made significant strides in the development of brain-computer interfaces for controlling prosthetic hands. By training rhesus monkeys to use neural signals for hand posture control, the researchers have shifted focus from movement velocity to hand position, resulting in improved fine mot...

Study Reveals How Brain Divides Continuous Experiences into 'Movie Scenes'
New research shows that the brain organises daily experiences into segments, much like scenes in a movie. The study reveals that memory boundaries are not solely determined by external factors, but also by personal priorities and interpretations. The findings indicate that we have more control over how we perceive and recall experiences than previo...

Largest Brain Map Ever Reveals 140,000 Neurons and New Nerve Cell Types in Fruit Fly Brain
A new brain map of the fruit fly, Drosophila melanogaster reveals nearly 140,000 neurons and over 54.5 million synapses. Led by neuroscientists Mala Murthy and Sebastian Seung, the research has uncovered 4,581 previously unknown types of neurons. The project took over four years to complete, relying on AI-assisted electron microscopy.

Monkeys Study Uncovers Science Behind 'Choking Under Pressure'
A recent study published in the journal Neuron reveals insights into why both monkeys and humans struggle under pressure. Researchers found that stress impairs brain signals crucial for movement execution when faced with high rewards. The study, involving monkeys completing tasks for water, demonstrated that performance declined when potential rewa...

Why We Forget Thoughts Instantly? Brain Functions Behind Memory Loss Explained
Forgetting a thought you just had is a common experience. This happens due to the brain’s working memory, which can only hold a limited amount of information at any given time. It juggles multiple thoughts, which can lead to information slipping away. Recreating the context where you had the thought may help in retrieving it. Neuroscientists like...

Placebo Effect Link Discovered With Previously Unassociated Parts of the Brain
Patients suffering from chronic pain have limited treatment options, often relying on medications like opioids that come with harmful side effects and high addiction risks. A new study in mice, published in Current Biology journal, suggests a new way to use the placebo effect for treating chronic pain. By activating specific neurons in the brain li...

COVID-19 Virus’ Link That Potentially Increases Brain Infection Risk Found, Claims Study
A recent study has revealed that SARS-CoV-2, the virus responsible for the COVID-19 pandemic, might be using an unexpected method to infect the brain. Researchers found that mutations in the virus' spike protein allow it to enter brain cells through a "back door," a process that might explain the neurological symptoms observed in some COVID-19 pati...

New Study Reveals the Brain Stores Multiple Copies of Every Memory
Recent research sheds new light on how the brain stores and manages memories, revealing that it maintains at least three distinct copies of each memory. This study, conducted on rodents, provides valuable insights into the brain's memory encoding process and suggests that multiple types of neurons play a role in storing these memories. The research...
