Targeting Glucose May Spark Neurogenesis

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

Summary: Neural stem cells, which create new neurons in the brain, become less active with age due to elevated glucose levels. Researchers found that by knocking out the glucose transporter gene GLUT4 in older mice, they could significantly increase the production of new neurons.

This discovery opens up potential pathways for both genetic and behavioral interventions to stimulate brain repair, including the possibility of a low-carbohydrate diet. The findings could help treat neurodegenerative diseases and aid in brain recovery after injury.

Brain scan study shows what happens in the brain when a person with schizophrenia hears voices

Posted by in categories: biotech/medical, neuroscience

Patients with certain mental disorders, including schizophrenia, often hear voices in the absence of sound.


Auditory hallucinations are likely the result of abnormalities in two brain processes: a broken corollary discharge that fails to suppress self-generated sounds, and a noisy efference copy that makes the brain hear these sounds more intensely than it should. That is the conclusion of a study published October 3 in the open-access journal PLOS Biology by Xing Tian, of New York University Shanghai, China, and colleagues.

In the new study, researchers carried out electroencephalogram (EEG) experiments measuring the brain waves of 20 patients diagnosed with schizophrenia with and 20 patients diagnosed with who had never experienced such hallucinations.

Tracking neurons across days with high-density probes

Imagine trying to understand the brain’s activity over time—an incredibly complex and dynamic process that happens at different speeds.


To solve this problem, we developed a pipeline called UnitMatch, which operates after spike sorting. Before applying UnitMatch, the user spike sorts each recording independently using their preferred algorithm. UnitMatch then deploys a naive Bayes classifier on the units’ average waveform in each recording and tracks units across recordings, assigning a probability to each match.

Synchron Brain Implant Achieves New Milestone in Controlling Amazon, Apple Technology

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

With this success, Synchon is looking to take its experiments to the next level by adding more participants in a larger study. CEO Tom Oxley claims that their future study would focus more on ‘gathering brain data to improve the BCI.

Are Brain-Computer Interfaces the Future of Technology?

Different companies have already begun their developments and clinical trials of their brain-computer interfaces (BCIs) which need to be implanted on human test subjects, centering mostly on paraplegic patients. One of the most famous companies behind this is Elon Musk’s Neuralink, and their first patient, Noland Arbaugh, testified how the implant can help in controlling technology, and in his case, gaming.

139,000 Neurons of Adult Fruit Fly Brain Mapped For The First Time

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

Unlocking the complexities of the fruit fly brain is a crucial step toward understanding the human brain. Fruit flies share many genetic similarities with humans, making them a valuable model organism for studying brain functions as well as diseases.

“An estimated 75% of human genes related to diseases have homologs in the fly genome,” Sebastian Seung, co-leader of the research team, told Interesting Engineering (IE).

Stanford Medicine study hints at ways to generate new neurons in old brains

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

The same technique could also be applied to studies of brain damage, Ruetz said. “Neural stem cells in the subventricular zone are also in the business of repairing brain tissue damage from stroke or traumatic brain injury.”

The glucose transporter connection “is a hopeful finding,” Brunet said. For one, it suggests not only the possibility of designing pharmaceutical or genetic therapies to turn on new neuron growth in old or injured brains, but also the possibility of developing simpler behavioral interventions, such as a low carbohydrate diet that might adjust the amount of glucose taken up by old neural stem cells.

The researchers found other provocative pathways worthy of follow-up studies. Genes relating to primary cilia, parts of some brain cells that play a critical role in sensing and processing signals such as growth factors and neurotransmitters, also are associated with neural stem cell activation. This finding reassured the team that their methodology was effective, partly because unrelated previous work had already discovered associations between cilia organization and neural stem cell function. It is also exciting because the association with the new leads about glucose transmission could point toward alternative avenues of treatment that might engage both pathways, Brunet said.
