Summary: Delve into the fascinating world of neuroscience with this week’s exceptional discoveries.
Starting with a promising ray of hope for tinnitus sufferers, researchers have unveiled the efficacy of low-level laser therapy as a potential treatment.
In our quest to understand Alzheimer’s disease, we’ve gained new insights from a different perspective – the liver-brain axis. On a similar note, probiotics have emerged as potential detoxifiers of mercury in our gut.
Concurrently, a fresh perspective on alcohol use disorder has challenged traditional notions of “holding one’s liquor”.
To conclude, we deepen our knowledge of self-awareness, with the discovery of a crucial brain structure, the anterior precuneus.

Welcome to our review of the most captivating neuroscience developments of the week from Neuroscience News.
Let’s journey through the most pioneering research that had our audience engrossed over the past week.
#5: Low-Level Laser Therapy Effective for Tinnitus Treatment
In the relentless search for successful tinnitus treatments – a distressing condition affecting a staggering 750 million people globally – scientists have discovered low-level laser therapy to be exceptionally effective.
The research showcased excellent results from both laser acupuncture and transmeatal low-power laser stimulation. These treatments are thought to enhance peripheral irrigation, stimulate the proliferation of inner ear cells, and promote collagen production.
This groundbreaking discovery paves the way for improved treatment strategies for tinnitus across various medical fields.
#4: Liver-Brain Axis Plays Key Role in Alzheimer’s
Researchers unveiled new evidence that positions the liver at the heart of Alzheimer’s disease progression.
Abnormal protein deposits and oxidative stress, hallmarks of liver dysfunction, were detected in Alzheimer’s disease mouse models. These findings suggest significant changes in the liver-brain axis that may correlate with behavior shifts and stress responses.
This crucial research underscores the need to consider systemic factors and peripheral organs in our fight against Alzheimer’s disease.
#3: Probiotics May Be Unexpected Heroes in Detoxifying Mercury in Gut
It appears our gut bacteria may serve as powerful allies in hindering the absorption of toxic metals like mercury while fostering the intake of beneficial ones such as iron.
Scientists honed in on the genes that allow bacteria to transmute perilous mercury into less harmful forms. Harnessing this information, they devised a probiotic specifically targeted to detoxify a particular type of mercury common in human diets.
They aspire to broaden their investigation to evaluate how gut microbes interact with other metals to improve our body’s metal absorption.
#2: Alcohol Use Disorder: More Alcohol, More Impairment, Regardless of Drinking Habits
The concept of “holding one’s liquor” proves to be intricate, especially among heavy drinkers.
Findings from the study suggest that while individuals suffering from alcohol use disorder (AUD) may display less impairment after a standard intoxicating dose, they exhibit markedly more impairment aligned with their customary heavier drinking habits.
This heightened impairment level does not return to baseline even three hours after drinking, providing crucial insights into alcohol tolerance limits among heavy drinkers and AUD sufferers.
#1: Sense of Self: The Brain Structure That Holds Key to “I”
Scientists have pinpointed a small structure in the brain, the anterior precuneus, as pivotal in constructing our physical self or “I”.
The anterior precuneus is a component of a network of brain regions that amalgamate information about our location, motion, and bodily sensations to generate our self-awareness.
Disruptions in the electrical activity within the anterior precuneus result in modified perceptions of our place in the world, providing novel insights into our understanding of self-awareness and consciousness.
