Scientists are closer to understanding how much meditation training is needed to improve brain–computer interface performance

Posted by in categories: biotech/medical, computing, health, neuroscience

Mindfulness-based awareness training can help people learn to better control brain-computer interfaces. But a new study has found that a single guided mindfulness meditation exercise isn’t enough to boost performance. The findings, published in Frontiers in Human Neuroscience, suggest that a longer period of meditation is needed in order for people to experience observable improvements.

The authors of the research are interested in exploring the potential benefits of using mindfulness meditation as a training tool to improve the performance of brain-computer interfaces, which allow individuals to control machines or computers directly from their brain, bypassing the traditional neuromuscular pathway. These devices have the potential to greatly benefit people with conditions such as spinal cord injuries, stroke, and neurodegenerative diseases like amyotrophic lateral sclerosis (ALS).

Previous studies have shown that one of the most effective signals for brain-computer interface control is the sensorimotor rhythm produced in the primary sensorimotor areas during motor imagery. However, not everyone is able to effectively control brain-computer interfaces, with approximately 20% of the population being “BCI-inefficient” even with extensive training. Therefore, researchers are looking for ways to improve performance, and one potential method is through meditation.

Sacrificing Sleep For Productivity Gave ‘Brain Pain,’ Says Elon Musk

Posted by in categories: Elon Musk, neuroscience

Tesla CEO Elon Musk, who last year described himself as “fairly nocturnal,” is known for his history of working through the night and even sleeping beneath his desk to meet deadlines. Recently, however, he revealed that he is endeavoring to secure at least six hours of sleep every night.

In an interview with CNBC on Tuesday, Musk said, “I’ve tried to sleep less, but even though I’m awake more hours, I get less done. And the brain pain level is bad if I get less than six hours of sleep per night.”

Musk said he often works seven days per week and only takes “two or three” truly workless vacation days yearly. However, he said he doesn’t expect his employees to model that behavior.

Intelligent brains take longer to solve difficult problems, shows simulation study

Posted by in category: neuroscience

Do intelligent people think faster? Researchers at the BIH and Charité—Universitätsmedizin Berlin, together with a colleague from Barcelona, made the surprising finding that participants with higher intelligence scores were only quicker when tackling simple tasks, while they took longer to solve difficult problems than subjects with lower IQ scores.

In personalized brain simulations of the 650 participants, the researchers could determine that brains with reduced synchrony between literally “jump to conclusions” when making decisions, rather than waiting until upstream brain regions could complete the processing steps needed to solve the problem.

In fact, the brain models for higher score participants also needed more time to solve challenging tasks but made fewer errors. The scientists have now published their findings in the journal Nature Communications.

Alzheimer’s: New blood biomarker may predict risk of cognitive decline

Posted by in categories: biotech/medical, neuroscience

A new study suggests that astrocytes, a type of brain cell, are important for connecting amyloid-β with the early stages of tau pathology, which could change how we define early Alzheimer’s disease.

An AAV-CRISPR/Cas9 strategy for gene editing across divergent rodent species

Posted by in categories: bioengineering, biotech/medical, genetics, neuroscience

Crispre cas 9.


A major issue in neuroscience is the poor translatability of research results from preclinical studies in animals to clinical outcomes. Comparative neuroscience can overcome this barrier by studying multiple species to differentiate between species-specific and general mechanisms of neural circuit functioning. Targeted manipulation of neural circuits often depends on genetic dissection, and use of this technique has been restricted to only a few model species, limiting its application in comparative research. However, ongoing advances in genomics make genetic dissection attainable in a growing number of species. To demonstrate the potential of comparative gene editing approaches, we developed a viral-mediated CRISPR/Cas9 strategy that is predicted to target the oxytocin receptor (Oxtr) gene in 80 rodent species. This strategy specifically reduced OXTR levels in all evaluated species (n = 6) without causing gross neuronal toxicity. Thus, we show that CRISPR/Cas9-based tools can function in multiple species simultaneously. Thereby, we hope to encourage comparative gene editing and improve the translatability of neuroscientific research.

The development of comparative gene editing strategies improves the translatability of animal research.

Philosophy Portal: Brain in a Vat

Posted by in categories: biotech/medical, neuroscience, transhumanism

Imagine a world where every conceivable facet of your reality is nothing more than sensory experience devoid of any real meaning; And that your emotions, organs, and even your closest relationships were nothing but pleasurable impulses being transmitted directly into your brain.

This is the hypothesis posited by the Brain in a Vat theory. If an evil scientist (or rich transhumanist, whichever you prefer) were to take your brain, submerge it in a jar or vat of nutrients, in theory, you could be force fed the information you process on a daily basis.

If your neurons were connected to some type of hardware and/or software that could continuously provide the necessary stimuli, you’d be ripe for this process.

Brain Shape’s surprising impact on thoughts and behavior, study reveals

Posted by in category: neuroscience

Discover the intriguing findings that shed light on the significance of brain shape and its influence on brain activity.

Groundbreaking research conducted by a team of Australian scientists suggests that the shape of our brains may affect us more than we think. Nobody wonders if their brain shape is an important parameter. Most people attribute brain size to behaviors even more.

However, it turns out that shape has a more significant impact on our thoughts and behavior than the connections and signals between neurons.
