- A research team led by Professor Jang Kyung-in at DGIST developed a brain-implantable dopamine measurement sensor for applying a stable structure based on a three-electrode system. - The developed sensor facilitates a real-time dopamine concentration analysis by using only one flexible probe, increasing expectations for its application for developing customized probes for patients with degenerative brain diseases.

While anger and aggression are instinctive behaviors found across many species, leaving these emotions unchecked can lead to conflict and violence. In a recent study, researchers at Tohoku University demonstrated that neuronal-glial interactions in the cerebellum determine the degree of aggression exhibited by mice. This suggests that future therapeutic methods could adjust glial activity in the cerebellum to help reduce unwanted aggression.

A group of researchers at Osaka University used a noninvasive method to evaluate Cerebrovascular Autoregulation (CVAR) in patients after out-of-hospital cardiac arrest. The mortality rate increased significantly with the duration of time that CVAR was undetectable. It has been suggested that CVAR, a function that is normally present in the normal state, may be impaired after cardiac resuscitation. However, the relationship between CVAR function and patient prognosis has been unclear. The research examined CVAR over time, using the moving Pearson correlation coefficient calculated from regional cerebral oxygen saturation and mean blood pressure data, and performed a survival analysis using the presence or absence of CVAR as a time-dependent covariate. The findings of this study may first be useful in predicting neuroprognosis after cardiac resumption and may help avoid early withdrawal of treatment in those who may recover. In addition, they suggest that treatment and management that maintains proper CVAR after cardiac resumption may improve patient prognosis, which may be applied to the management of post-cardiac arrest resuscitation based on cerebral circulation to optimize treatment for each individual patient.

Have you ever studied hard for a test the night before, only to fail miserably the next day? Alternatively, you may have felt unconfident after studying the night before when, to your astonishment, you recall effortless the content on test day. This discrepancy may be down to the separate and independent way in which our brain processes short- and long-term memory, Tohoku University researchers have revealed.

To promote the message of productive ageing, Lingnan University (LU) joined hands with RTHK Radio 5, New Territories West Elder Academies Cluster, and Wofoo Social Enterprises to organise O Camp 2.0 on LU campus on 17 June. The event, themed ‘Intergenerational Day Camp’, aims to promote intergenerational harmony and offer LU students a platform to assist older people in experiencing university life. They also spared time to collaborate with secondary and primary school students to set a first leisure technology SDG World Record for enhancing elderly’s interest in gerontechnology’s application in a bid to improve their quality of life as well as build up Hong Kong into an age-friendly city.

It’s not unusual for many of us to reach for a cup of coffee or cup of tea whilst focusing our attention on a screen. Scientists have long pondered whether our hand movements influence our spotlight attention. And now a group of researchers from Tohoku University have discovered that our spotlight attention and the attention paid to our moving hands operates via independent mechanisms.

The Nobel prize winning physicist Niels Bohr once said, “An expert is a (person) that has made all the mistakes that can be made in a narrow field.” This idea that to master a skill we must learn from our mistakes and avoid making them in future has long been recognized; however, the brain mechanisms and pathways that control this ability have been poorly understood. We revealed a specific brain pathway that allows us to identify and learn from our mistakes to guide better decision-making in future. Our work is an important step towards understanding how the brain controls our daily choices and behavior. The identification of these cells as ‘mistake signalers’ may also help to guide new treatments for mental health conditions associated with impaired decision-making ability.

Changes in our REM sleep patterns could potentially be used to diagnose the severity of epilepsy, a new study by Tohoku University researchers has suggested. They showed that astrocytes - star-shaped glial cells that control the local ionic and metabotropic environment of the brain - exhibit an acid response with REM sleep in mice. They theorize that the acid response could be the underlying drive for specific information processing and generating plasticity during sleep.
