Breakthrough: New Blood Test Predicts Schizophrenia Risk

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

Diagnosing schizophrenia as early as possible helps minimize the toll the neurological disorder takes on the body and the mind. Unfortunately the condition’s signs can be difficult to spot in the early stages.

That’s why researchers led by a team from the Indiana University School of Medicine have developed a test which offers a relatively simple and reliable way to check for current schizophrenia severity and future risk.

“Psychosis usually manifests in young adulthood – a prime period of life,” says neuroscientist Alexander Niculescu from the Indiana University School of Medicine. “Stress and drugs, including marijuana, are precipitating factors on a background of genetic vulnerability.”

Fluicell partners with Swedish researchers to 3D bioprint complex brain cell structures

Posted by in categories: 3D printing, bioprinting, biotech/medical, neuroscience

Scientists from medical tech company Fluicell have partnered with clinical R&D firm Cellectricon and the Swedish Karolinska Institutet university to 3D bioprint neural cells into complex patterns.

Using the microfluidic printheads featured on Fluicell’s Biopixlar platform, the researchers were able to accurately arrange rat brain cells within 3D structures, without damaging their viability. The resulting cerebral tissues could be used to model the progress of neurological diseases, or to test the efficacy of related drugs.

“We’ve been using Biopixlar to develop protocols for the printing of different neuronal cells types, and we are very pleased with its performance,” said Mattias Karlsson, CEO of Cellectricon. “This exciting technology has the potential to open completely new avenues for in-vitro modeling of a wide range of central and PNS-related diseases.”

Dementia: Could a new blood test predict it 15 years before symptoms?

Posted by in categories: biotech/medical, neuroscience

Researchers are devising a blood test screening for 11 newly discovered biomarkers of dementia. They say the test could predict its development 15 years before symptom onset.

Brain Boosters from Exercise and Diet

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

Studies show that physical activity is actually a mental health exercise. One article that states just 15 minutes of walking, especially in the out-of-doors, can boost mood and reduce feelings of depression.

People seem to think more clearly after a brisk walk as well. It makes sense. As the heart pumps oxygen and nutrients to working muscles, the brain gets the same benefits.

Are there foods that might help our brains stay focused? In 2015, scientists reported on a diet that was found to help slow the gradual decline in cognitive function we may experience as we age. It was a hybrid of the Mediterranean diet and the DASH diet (Dietary Approaches to Stop Hypertension) cutely named the MIND diet (Mediterranean-DASH Diet Intervention for Neurodegenerative Delay).

Neurotechnologies: The Next Technology Frontier

Posted by in category: neuroscience

For millennia, the human brain has been a largely unexplored frontier. Relative to the whole of human history, studying, understanding, and influencing human thought and consciousness is a radically new endeavor. Only in the twenty-first century has science truly begun to progress far enough into the field of neuroscience for effective neurotechnologies to begin to take shape.

The implications of neurotechnologies for society are vast. From pharmaceuticals that improve quality of life, to brain imaging that revolutionizes our conception of human consciousness, neurotechnologies stand to change our understanding of ourselves and harness the power of the brain and nervous system’s myriad functions to promote human thriving.

What are neurotechnologies?

Brain augmentation and neuroscience technologies: current applications, challenges, ethics and future prospects

Posted by in categories: biotech/medical, chemistry, employment, ethics, health, mathematics, neuroscience, robotics/AI

This isn’t rocket science it’s neuroscience.


Ever since the dawn of antiquity, people have strived to improve their cognitive abilities. From the advent of the wheel to the development of artificial intelligence, technology has had a profound leverage on civilization. Cognitive enhancement or augmentation of brain functions has become a trending topic both in academic and public debates in improving physical and mental abilities. The last years have seen a plethora of suggestions for boosting cognitive functions and biochemical, physical, and behavioral strategies are being explored in the field of cognitive enhancement. Despite expansion of behavioral and biochemical approaches, various physical strategies are known to boost mental abilities in diseased and healthy individuals. Clinical applications of neuroscience technologies offer alternatives to pharmaceutical approaches and devices for diseases that have been fatal, so far. Importantly, the distinctive aspect of these technologies, which shapes their existing and anticipated participation in brain augmentations, is used to compare and contrast them. As a preview of the next two decades of progress in brain augmentation, this article presents a plausible estimation of the many neuroscience technologies, their virtues, demerits, and applications. The review also focuses on the ethical implications and challenges linked to modern neuroscientific technology. There are times when it looks as if ethics discussions are more concerned with the hypothetical than with the factual. We conclude by providing recommendations for potential future studies and development areas, taking into account future advancements in neuroscience innovation for brain enhancement, analyzing historical patterns, considering neuroethics and looking at other related forecasts.

Keywords: brain 2025, brain machine interface, deep brain stimulation, ethics, non-invasive and invasive brain stimulation.

A unifying theory explains seemingly contradictory biases in perceptual estimation

Posted by in category: neuroscience

Despite a long history of studying perceptual biases in neuroscience, many of the biases remain difficult to explain and even appear to be contradictory. The authors propose a unifying theory that sheds new light on such puzzling perceptual biases.

Study: Traumatic brain injury leads to widespread changes in neural connections

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

A head injury serious enough to affect brain function, such as that caused by a car accident or sudden fall, leads to changes in the brain beyond the site of impact, Tufts University School of Medicine scientists report in the journal Cerebral Cortex. In an animal model of traumatic brain injury, the researchers found that both hemispheres work together to forge new neural pathways in an attempt to replicate those that were lost.

“Even areas far away from the injury behaved differently immediately afterward,” says first author Samantha Bottom-Tanzer, an MD/Ph. D. student in neuroscience at the School of Medicine. “Traumatic brain injury research tends to focus on the region of injury, but this study makes a good case that the entire brain can be affected, and imaging in distal regions can provide valuable information.”

Bottom-Tanzer and colleagues are the first to use an combining fluorescent sensors of neuronal activity and electrodes to record how many parts of the brain talk to each other after a brain injury. The team tracked neural activity in mice for up to three weeks post-injury during periods of exercise and rest.
