Hokkaido University researchers have shown how chronic pain leads to maladaptive anxiety in mice, with implications for treatment of chronic pain-related psychiatric disorders in humans.

A recent infant study suggests that the visual experience in daily life contributes to the emergence of upper visual field bias for faces.

Osaka City University* study suggests memories are formed through an integration across brain regions via burst activity in amygdala-prefrontal neuronal ensembles during memory acquisition, and then hippocampal-prefrontal synchrony during post-experience sleep. (Osaka City University has now changed its name as Osaka Metropolitan University)

A research team led by the National Institute for Physiological Sciences and joined by Hokkaido University explored the role of pain neurons in the regulation of endotoxic death. They found that peptide named Reg3γ acts as a pain neuron-enriched brain-targeted hormone that protects the host from endotoxic death.

A great deal of discussion is underway on what appears to be the latest wave of migration from Sri Lanka. While the exact scale and nature of youth migration remain unclear, the costs of brain drain dominate these discussions. The brain drain concern is valid, yet focusing on it alone can limit our understanding of the complex implications of migration. This blog argues that apart from its challenges, youth migration can also present some surprising opportunities for socio-economic development if strategically managed.

Our brain maps out our body to facilitate accurate motor control. For a century, the body map has been thought to have applied to all types of motor actions. Now, a research group has revealed that the body relies on multiple maps based on the choice of motor system.

We have succeeded in establishing a mouse model that develops gastric cancer closely resembling advanced human gastric cancer. Using this model, we have discovered gastric cancer stem cells, i.e. Lgr5+ gastric cancer cells, essential for the development, maintenance, and metastasis of cancer. Our study provides an experimental system that enables detailed analysis of highly malignant gastric cancer and is expected to lead to the development of a breakthrough treatment for advanced human gastric cancer.

Micro-plastics cross blood brain barrier, Stomach cancer atlas, Omicron variant isolated, 120-year-old reaction turned on its head and Reporting through the coup, all in the December Editor's Choice. Plus our latest podcast: Decentralization and Democracy in Myanmar.

A joint research team at the Division of Biotechnology, DGIST, confirmed that microplastics(MPs) ingested orally accumulate in the brain and act as neurotoxic substances.

The joint research team of Prof. Hongsoo Choi(DGIST) & Prof. Sung Won Kim(Seoul St. Mary’s Hospital), developed an hNTSC-based microrobot for minimally invasive delivery into the brain tissue via the intranasal pathway

Feeling unsure of yourself? Your brain’s background noise may be interfering with the long memory signals communicated by your neurons’ electrical chatter.

Novel design of brain chip implant allows for measuring neuronal activity while simultaneously delivering drugs to the implant site

Paris, 29 September — UNESCO and the L'Oréal Foundation are unveiling the winners of this year’s International Prize for Women in Science, which honours five eminent women scientists with exceptional careers from the five regions of the world, as it has done annually since 1998.

An algorithm that detects events occurring across different time and geographical scales on social media could enable a more timely response to emerging events.

New research published in Stem Cell Reports has found elevated cholesterol supply from astrocytes to neurons in the model of Alzheimer's disease (AD) brains, suggesting that modulating brain cholesterol could be explored in the search of treatment options for the devastating, degenerative disease.

Researchers from the University of Tsukuba and Kyoto University find that capillary blood flow in the brain, which is important for delivering oxygen and nutrients and removing waste products, is increased in mice during the dream-active phase of sleep.

Recreating major pathological features of Parkinson’s disease in a lab-grown, human mini-brain will help researchers to explore new treatments. This is the first time that Lewy bodies, a hallmark of Parkinson’s disease in patients’ brains, have been produced in the laboratory, offering new insights into the disease.

Neuroscientists develop a new approach to better understand the neural mechanism underlying deductive and inductive reasoning

Experiments conducted on genetically modified mice clarify the role of a protein in regulating properties of specific hippocampal neural circuits

A new, energy-efficient method of electrical brain stimulation developed by researchers from the Daegu Gyeongbuk Institute of Science and Technology could aid stroke rehabilitation and has few side effects.

Our brain has no lymphatic system; however, it does have fluid flow, which is believed to play a role in removing waste from the brain. However, the fluid's point of origin and fluid flow is still unclear. The “multi-scale stable isotopes imaging” project in Hokkaido University aims to solve this mystery using advanced technology. “We would not have been able to perform this study without Hokkaido University’s MRI technology and the isotope microscope,” said the project’s PI, Professor Kohsuke Kudo of the Department of Radiology, Faculty of Medicine.

Cryo-electron microscopy and computer simulations uncover how a cellular protein helps transport omega-3 fatty acids to the brain and eye, with implications for drug development.

Chuo University and Hokkaido University researchers have found that infants take less than a second to completely process visual information and have the same temporal limitation in processing visual information as seen in adults.

Single-cell gene studies are clarifying the roles of the brain’s specialised immune cell in Alzheimer’s disease and offer new avenues for treatment of this incurable condition.

An ‘eat-me’ signal displayed on cell surfaces requires activation of a lipid-scrambling protein by a nuclear protein fragment.

Through a series of prosocial choice tasks, researchers reveal prosocial and antisocial characteristics in male convict cichlid fish. The fish distinguish between female breeding partners, unknown females, and rival males by adjusting their actions to either provide food for both them and the females or avoid providing food for the rival males.
