Neuralink, Elon Musk’s brain implant startup, quietly raises an additional $43M

Posted by in categories: computing, Elon Musk, finance, neuroscience

Neuralink, the Elon Musk-founded company developing implantable chips that can read brain waves, has raised an additional $43 million in venture capital, according to a filing with the SEC.

The filing published this week shows the company increased its previous tranche, led by Peter Thiel’s Founders Fund, from $280 million to $323 million in early August. Thirty-two investors participated, according to the filing.

Neuralink hasn’t disclosed its valuation recently. But in June, Reuters reported that the company was valued at about $5 billion after privately-executed stock trades.

The neuropeptidergic connectome of C. elegans

Posted by in categories: biotech/medical, neuroscience

An amazing graph theoretic analysis of the C. elegans neuropeptide connectome!


Neuromodulation by peptides is essential for brain function. By comprehensively mapping neuropeptide signaling in the nematode C. elegans, Ripoll-Sánchez et al. define a dense wireless network whose organization differs in important ways from wired brain circuits. This network is a prototype for understanding neuropeptide signaling networks in larger brains.

The brain can exhibit signs of consciousness long after the heart stops, study finds

Posted by in category: neuroscience

A study revealed that one-third of cardiac arrest survivors experienced consciousness, with EEG showing brain activity despite heart stoppage. This groundbreaking finding challenges current understandings of brain function during cardiac emergencies.

Higher Risk of Alzheimer’s in Women Linked to Immunity and Metabolism

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

Cleveland Clinic researchers analyzed genes and brain tissue of patients with Alzheimer’s and found that differences in brain immunometabolism – the interactions between the immune system and the ways cells create energy – may contribute to women’s increased risk for the disease and its severity.

The findings, published in Alzheimer’s and Dementia, offer important insight into developing sex-specific treatment and prevention options for Alzheimer’s disease, the sixth-leading cause of death in the United States.

“Our immune systems depend on communication between different cell types in our bodies, which are fueled by energy created from unique metabolic processes,” said Justin Lathia, Ph.D., vice chair of the Department of Cardiovascular and Metabolic Sciences and co-author on the paper. “As sex influences both the immune system and metabolic process, our study aimed to identify how all of these individual factors influence one another to contribute to Alzheimer’s disease.”

Brain’s Limitations Uncovered: Scientists Debunk Long-Held Beliefs About Neural Rewiring

Posted by in category: neuroscience

Contrary to popular belief, the brain does not have the capability to rewire itself to compensate for loss of sight, amputations, or stroke-related damage, according to scientists from the University of Cambridge and Johns Hopkins University.

In a recent paper published in eLife, Professors Tamar Makin (Cambridge) and John Krakauer (Johns Hopkins) argue that the notion that the brain, in response to injury or deficit, can reorganize itself and repurpose particular regions for new functions, is fundamentally flawed – despite being commonly cited in scientific textbooks. Instead, they argue that what is occurring is merely the brain being trained to utilize already existing, but latent, abilities.

New Device Can Keep Brain Alive for Hours Without Body

Posted by in categories: biotech/medical, neuroscience

Researchers in Texas have developed a method to keep a brain alive and functioning for several hours without being connected to the body — a truly weird scientific experiment that recalls the head in jars bit in the iconic cartoon “Futurama.”

A team led by the University of Texas Southwestern Medical Center in Dallas took two pigs and severed connections between their heads and bodies, instead hooking the brains up to a device they call the extracorporeal pulsatile circulatory control (EPCC), which they detailed in a paper published in the journal Scientific Reports. The machine keeps blood pumping through the brain, mimicking the natural flow when it’s connected to the rest of the body.

New research raises questions about caffeine’s impact on brain plasticity

Posted by in categories: biotech/medical, neuroscience

A recent study has raised questions about the impact of chronic caffeine consumption on our brain’s ability to adapt and learn. In a new study published in Frontiers in Psychiatry, scientists found that long-term caffeine users may exhibit decreased brain plasticity, a critical factor in the processes of learning and memory, when subjected to a brain stimulation protocol.

Caffeine is a common stimulant found in coffee, tea, soda, and other beverages. It’s known to help with alertness and concentration, but its effects on the brain’s ability to change and adapt over time, a process called plasticity, have been less clear.

Previous studies have shown mixed results when it comes to caffeine’s influence on brain plasticity. Some studies hinted that caffeine might hinder the brain’s ability to learn and adapt, while others suggested potential benefits. The researchers conducted this study to investigate the effects of caffeine on human brain plasticity, specifically focusing on its impact on long-term potentiation (LTP) and its potential interaction with a neuromodulation technique called repetitive transcranial magnetic stimulation (rTMS).
