Welcome to our weekly review of the five most popular articles in neuroscience.
This week, we delve into the realms of belief-altering perceptions, gut-brain links to Alzheimer’s, the legal status of brain organoids, a new antidepressant with fewer side effects, and the profound impact of exercise on brain health.
These stories have been buzzing in our neuroscience community, and they’re certain to pique your curiosity.
A study tested the influence of beliefs on tactile perception. Researchers found that hypnotic suggestions could alter an individual’s tactile discrimination threshold. When participants under hypnosis believed their index finger was larger, they could distinguish two closely-spaced needle points more accurately. This ability was impaired when they were made to believe their finger was smaller.
The study, backed by concurrent brain activity measurements, gives us valuable insights into the top-down influences of beliefs on perception. It suggests the human mind’s extraordinary ability to influence perceptual experiences.
A new study adds weight to the hypothesis of a gut-brain link in Alzheimer’s disease. Researchers identified certain gut bacteria that could potentially increase or decrease the risk of developing Alzheimer’s. This correlation between gut health and neurodegenerative disease is a reminder that our overall health is interconnected.
The work provides hope for personalized treatments involving dietary changes or probiotics to positively influence our gut microbiome, immune system, and brain function.
Researchers discuss the legal status of human brain organoids. These lab-grown replicas of human brains, produced from stem cells, have sparked debate about their potential juridical personhood.
The authors of this study assert that brain organoids do not fulfill the requirements to be considered natural persons, highlighting the urgent need for a legal framework to govern this emerging field of research.
Researchers discovered that the delta opioid receptor agonist, KNT-127, could be more effective and cause fewer side effects than many current drugs for the treatment of depression.
In a mouse model of depression, KNT-127 demonstrated anti-depressant-like effects, prevented neuronal inflammation, and reduced newborn neuronal death.
While further research is needed, this study offers hope for an effective and less burdensome treatment option for depression.
A new article explores the profound impact of exercise on the brain.
Research shows that regular physical activity promotes neurogenesis, particularly in the hippocampus, improves spatial memory, enhances sleep quality, increases brain plasticity, and reduces inflammation.
In essence, exercise seems to be a potent elixir for brain health and cognitive function, and it underscores the significant role that lifestyle factors play in maintaining our neurological health.
