Welcome to our weekly review of the five most popular articles in neuroscience.
This week, we delve into beliefs that change beliefs, the gut-brain connection to Alzheimer’s, the legal status of brain organoids, a new antidepressant with minimal side effects, and the powerful impact of exercise on mental health.
These stories have been buzzing around our neuroscience community, and they’re sure to pique your curiosity.
5. The Power of Imagination: Transforming tactile perception with the power of imagination
One study examined the influence of beliefs on tactile perception. Researchers have found that hypnotic suggestions can alter an individual’s tactile discrimination threshold. When participants under hypnosis believed that their index finger was larger, they could correctly identify two contiguous needle points. This ability is impaired when they are made to believe that their finger is small.
The study, supported by simultaneous measurements of brain activity, provides important insights into the top-down effects of beliefs on perception. It suggests that the human mind has a unique ability to influence perceptual experiences.
4. Diet and Dementia: Study Reveals Gut-Brain Link to Alzheimer’s
A new study adds weight to the hypothesis of a gut-brain connection in Alzheimer’s disease. Researchers have identified certain types of gut bacteria that may increase or decrease the risk of developing Alzheimer’s disease. This link between gut health and neurodegenerative disease reminds us that our overall health is interconnected.
The work holds promise for personalized treatments that include dietary changes or probiotics to positively impact our gut microbiome, immune system and brain function.
3. Microorganisms of human brain tissue cannot legally be considered “human”.
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 legal status.
The authors of this study have highlighted the need for a legal framework to guide this new field of research, as brain organoids do not meet the requirements to be considered a natural person.
2. A new antidepressant reduces stress and anxiety with fewer side effects
Researchers have found that the delta opioid receptor agonist (KNT-127) is more effective and may cause fewer side effects than many current medications for the treatment of depression.
In mouse depression, KNT-127 showed antidepressant-like effects, inhibited neuroinflammation, and reduced neonatal neuronal death.
Although more research is needed, this study offers the promise of an effective and less burdensome treatment option for depression.
1. Exercise and the Brain: Investigating the Neuroscience of Exercise
A new article explores the powerful effects of exercise on the brain.
Research shows that regular exercise increases neurogenesis, particularly in the hippocampus, improves spatial memory, improves sleep quality, increases brain plasticity, and reduces inflammation.
In essence, exercise appears to be a powerful elixir for brain health and cognitive function, and highlights the significant role lifestyle plays in maintaining our neurological health.
