Scientists Discover How Brain's "Population Clock" Guides Behavior

From Aristotle's musings on the nature of time to Einstein's theory of relativity, humanity has long pondered: how do we perceive and understand time? The theory of relativity posits that time can stretch and contract, a phenomenon known as time dilation. Just as the cosmos warps time, our neural circuits can stretch and compress our subjective experience of time. As Einstein famously quipped, "Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute".

Novel Drug Compound Reduces Sensory Hypersensitivity in Fragile X Mice

Boosting the activity of inhibitory interneurons in Fragile X mice reduced their hypersensitivity to sensory stimuli, according to a new Neuron study led by UCLA Health researchers.

Glucose-Sensing Neurons May Play a Role in Regulating Blood Sugar

The body's blood glucose level needs to be maintained in a relatively narrow range. It cannot be too high, as it can lead to diabetes, and it cannot be too low because it can cause fainting or even death.

Cryo-EM Reveals Structure of GABA Transporter

Using Cryo-EM, a powerful microscopy technique, researchers at IISc and collaborators have decoded the molecular architecture of a transporter protein controlling the movement of a key neurotransmitter.

Analyzing Glioma Progression and Implicating CPNs’ Long-Range Projections

Glioblastoma (GBM) is the most aggressive and lethal form of brain tumor. Despite treatment, GBM recurrence is inevitable and tends to occur outside surgical margins or in locations remote to the primary tumor, highlighting the central role played by tumor infiltration in this malicious disease.

Probiotic Bacteria may Help Maintain Brain Function in Aging Nematodes

A group from Nagoya University in Japan has discovered that when the diet of nematodes, tiny worms measuring about a millimeter or less in length, includes the bacteria Lactobacillus reuteri, the weakening of associative learning ability caused by aging does not occur.

New Technology can Help Probe the Connections Between the Brain and Gut

The brain and the digestive tract are in constant communication, relaying signals that help to control feeding and other behaviors.

New Mechanism to Maintain Astrocyte-Neuron Communication

Neurons and astrocytes are the two types of cells required by the brain to enjoy the scent of morning coffee and freshly baked cookies or to discern the warning smell of something burning.

Achieving 3D Printing Inside 'Mini-Organs' Growing in Hydrogels

Scientists from the NIHR Great Ormond Street Hospital Biomedical Research Centre (a collaboration between GOSH and UCL), London, and University of Padova, Italy, have shown for the first time how 3D printing can be achieved inside 'mini-organs' growing in hydrogels -- controlling their shape, activity, and even forcing tissue to grow into 'molds.'

Squids Use RNA Recording to Change Key Proteins Dynamically

Octopuses, cuttlefish, and squid are members of the diverse family of marine creatures known as cephalopods. They can be found in every ocean, from warm tropical seas that are shallow to cold, abysmal depths.

Can Temperature Influence the Octopus Neural Transcriptome?

Each cell has a finite set of instructions inscribed in its DNA. Life, on the other hand, is unpredictable, and when the situation changes, animals must change.

Scientists Discover the Mechanisms of Synaptic Pruning in Brain Development

Researchers at Kyushu University have uncovered the mechanisms of a fundamental yet critically under-looked phase in brain development: synaptic pruning.

New Delivery Mechanism Brings Messenger RNA to the Point of Need in Neurons

Brain cells manufacture proteins in every corner, including their long branches. Neurons missing this ability cause severe neurological disorders like disability and epilepsy.

Revealing How Human Brains Encode and Retain Value-Based Information

Researchers from the Center for Cognition and Sociality (CCS) within the Institute for Basic Science (IBS) recently announced the discovery of neurons that allow us to recognize others. The research team discovered that the neurons that deal with the information associated with different individuals are located in the CA1 region of the hippocampus.

RNA Regulatory Mechanism Involving Stress Granules Directly Regulates Alzheimer’s Development

A new research paper was published on the cover of Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 15, Issue 10, entitled, "Stress granules sequester Alzheimer's disease-associated gene transcripts and regulate disease-related neuronal proteostasis."

High-Resolution, Stable Brain Stimulation by Ultraflexible Nanoelectrodes

Conventional implantable medical devices designed for brain stimulation are often too rigid and bulky for what is one of the body's softest and most delicate tissues.

Game-Changing Research Shows Astrocytes as Key Regulators of Alzheimer's Disease Progression

Why do some people develop Alzheimer's disease while others don't? And, even more puzzlingly, why do many individuals whose brains are chock-full of toxic amyloid aggregates-;a telltale sign of Alzheimer's brain pathology-;never go on to develop Alzheimer's-associated dementias?

Study Reveals Mechanisms Behind Swallowing in Detail

Sensory cells in the vagus nerve can detect and locate food in the esophagus. Their signals help transport the food onward to the stomach. Signal failure leads to swallowing disorders, say a team led by Carmen Birchmeier at the Max Delbrück Center.

How the Disturbed Recycling Chain of Endoplasmic Reticulum Causes Neurodegenerative Diseases

Our cells are crisscrossed by a system of membrane tubes and pockets called the endoplasmic reticulum (ER). It is crucial for the production of biomolecules and is continuously built up and degraded.
