Neuralink’s first human patient able to control mouse through thinking, Musk says

Posted by in categories: biotech/medical, computing, Elon Musk, neuroscience

Feb 20 (Reuters) — The first human patient implanted with a brain-chip from Neuralink appears to have fully recovered and is able to control a computer mouse using their thoughts, the startup’s founder Elon Musk said late on Monday.

“Progress is good, and the patient seems to have made a full recovery, with no ill effects that we are aware of. Patient is able to move a mouse around the screen by just thinking,” Musk said in a Spaces event on social media platform X.

Musk said Neuralink was now trying to get as many mouse button clicks as possible from the patient.

New research offers hope to those affected by aggressive brain cancer

Posted by in categories: biotech/medical, life extension, neuroscience

New research from the University of Sussex holds promise for extending life expectancy and enhancing treatment options for a common and aggressive brain cancer affecting thousands in the UK annually and hundreds of thousands globally.

Published in the Journal of Advanced Science, the study revealed that the protein PANK4, previously overlooked, can hinder cancer cells’ response to chemotherapy in glioblastoma, an aggressive form of brain cancer and if the protein is removed, cancer cells respond better to the main chemotherapy drug used globally for the treatment of glioblastoma.

New genetic therapy shows promise for motor neuron disease and frontotemporal dementia

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

Macquarie University neuroscientists have developed a single-dose genetic medicine that has been proven to halt the progression of both motor neuron disease (MND) and frontotemporal dementia (FTD) in mice—and may even offer the potential to reverse some of the effects of the fatal diseases.

It may also hold opportunities for treating more common forms of dementia, such as Alzheimer’s disease, which is the second most common cause of death in Australia after heart disease.

The new treatment, dubbed CTx1000, targets pathological build-ups of the protein TDP-43 in cells in the brain and spinal cord.

Risk Factors for Death After Neurologic Immune-Related Adverse Events

Posted by in categories: biotech/medical, neuroscience

Neurologic immune-related adverse events (nirAEs) following immune checkpoint inhibitor therapy for cancer are frequent and varied; a recent study identified risk factors for death after nirAEs.


Recent cohort studies have demonstrated that neurologic immune-related adverse events (nirAEs) following immune checkpoint inhibitor (ICI) therapy for cancer are frequent, varied, and associated with higher overall survival (NEJM JW Neurol Sep 29 2023 and Neurology 2023; 101:e2472). Researchers conducted a retrospective cohort study of consecutive patients referred to a tertiary center during a 5-year period to characterize the clinical features of nirAEs and identify predictors of ICI response and survival.

The researchers identified 64 patients with confirmed nirAEs, 81% involving the central nervous system (CNS). The vast majority of CNS nirAE patients had encephalopathy, of which 73% were neither seropositive for well-characterized neural autoantibodies, nor had a distinctive encephalitis syndrome, nor had evidence of CNS inflammatory changes. The most common peripheral nervous system (PNS) syndrome was myasthenia and myositis (with or without myocarditis) overlap syndrome. Only 17% of PNS nirAE patients were seropositive. Steroids were given to 91% of nirAE patients after a median of 90 days of symptoms, and 48% received additional immunotherapy. At 1-month follow-up, 72% of nirAE patients showed improvement, 9% had worsened, and 17% had died. Among the 53 patients who survived the first month, median follow-up was 6 months; during follow-up, 30% died, most commonly of cancer progression or cancer-related complications. Death was associated with lung cancer (hazard ratio, 2.

To appreciate music, the human brain listens and learns to predict

Posted by in categories: media & arts, neuroscience

What is happening in the cerebral cortex when someone hears a melody?


Music has been central to human cultures for tens of thousands of years, but how our brains perceive it has long been shrouded in mystery.

Scientist shows Focused Ultrasound can Reach Deep into the Brain to Relieve Pain

Posted by in category: neuroscience

Research reveals potential of using low-intensity focused ultrasound for pain management. Scientists have found soundwaves from low-intensity focused ultrasound aimed at a place deep in the brain called the insula can reduce both the perception of pain and other effects of pain, such as heart rate changes.

You feel a pain, so you pop a couple of ibuprofen or acetaminophen. If the pain is severe or chronic, you might be prescribed something stronger — an opioid pain killer that can be addictive under some circumstances.

But what if you could ease pain by non-invasively manipulating a spot inside your brain where pain is registered?

Endovascular thrombectomy found to be beneficial for large ischemic stroke

Posted by in categories: biotech/medical, neuroscience

For patients with acute ischemic stroke and large cores, endovascular thrombectomy (EVT) improves clinical outcomes compared with medical management (MM), according to a study published online Feb. 7 in the Journal of the American Medical Association to coincide with the annual American Stroke Association International Stroke Conference, which was held from Feb. 7 to 9 in Phoenix.

Amrou Sarraj, M.D., from Case Western Reserve University in Cleveland, and colleagues describe the relationship between imaging estimates of irreversibly injured brain and at-risk regions and and EVT treatment effect in an exploratory analysis of the SELECT2 trial.

Adults with due to occlusion of the internal carotid or (M1 segment) and large ischemic core were randomly allocated to EVT versus MM across 31 global centers; the analysis included 336 patients.

Dopamine isn’t just a “feel good” chemical: New study reveals its role in reversal learning

Posted by in categories: chemistry, neuroscience

Researchers discovered dopamine plays a crucial role in adapting decisions to changing situations. Using PET and fMRI scans, they found dopamine increases in the brain’s reward center during task changes, aiding learning from mistakes.
