New Method Maps Gene Activity in Living Human Brain

Posted by in categories: biotech/medical, neuroscience

Summary: Researchers have developed a new method to profile gene activity in the living human brain, offering new insights into neurological conditions like epilepsy. By analyzing RNA and DNA collected from electrodes implanted in patients’ brains, the study linked molecular data with electrical recordings of seizures, creating a detailed snapshot of gene activity.

This approach enhances understanding of seizure networks, potentially improving the precision of epilepsy surgeries for patients who don’t respond to medication. Beyond epilepsy, the method could have applications in studying Alzheimer’s, Parkinson’s, and schizophrenia, advancing knowledge of brain disorders at the molecular level.

Researchers uncover potential new biomarker for psychosis diagnosis

Posted by in categories: biotech/medical, neuroscience

The current standard of care for psychosis is a diagnostic interview, but what if it could be diagnosed before the first symptom emerged? Researchers at the Del Monte Institute for Neuroscience at the University of Rochester are pointing toward a potential biomarker in the brain that could lead to more timely interventions and personalized care.

“Establishing such biomarkers could provide a key step in changing how we care for, treat, and offer interventions to people with ,” said Brian Keane, Ph.D., assistant professor of Psychiatry, Center for Visual Science, and Neuroscience at the University of Rochester Medical Center.

Keane recently co-authored an article in Molecular Psychiatry that identifies how MRI scans could reveal in people with psychosis.

Comparative prospects of imaging methods for whole-brain mammalian connectomics

Posted by in categories: nanotechnology, neuroscience

Neuroscience aficionados may enjoy my preprint that compares leading imaging technologies for whole-brain mammalian connectomics, now with major updates/improvements: Link: arxiv.org/abs/2405.


Mammalian whole-brain connectomes at nanoscale synaptic resolution are a crucial ingredient for holistic understanding of brain function. Imaging these connectomes at sufficient resolution to densely reconstruct cellular morphology and synapses represents a longstanding goal in neuroscience. Although the technologies needed to reconstruct whole-brain connectomes have not yet reached full maturity, they are advancing rapidly enough that the mouse brain might be within reach in the near future. Detailed exploration of these technologies is warranted to help plan projects with varying goals and requirements. Whole-brain human connectomes remain a more distant goal yet are worthy of consideration to orient large-scale neuroscience program plans. Here, we quantitatively compare existing and emerging imaging technologies that have potential to enable whole-brain mammalian connectomics.

Early adult binge drinking has lasting impact on aging brain in mice

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

In a new work, a team from the University of Pennsylvania tracked the impact of alcohol consumption from the age of 20 on brain health and came to disappointing conclusions.


UNIVERSITY PARK, Pa. — Binge drinking in early adults can lead to long-lasting and potentially permanent dysregulation in the brain, according to a new study in mice, led by researchers at Penn State. They found that neurons, cells that transmit information in the brain via electrical and chemical signals, showed changes following binge drinking were similar in many ways to those seen with cognitive decline.

These findings, published in the journal Neurobiology of Aging, reveal that binge drinking early in life may have lasting impacts that are predictive of future health issues, like Alzheimer’s disease and related dementias, the researchers said. The work could inform the development of therapeutics to help combat these changes — particularly in aging populations who may have given up alcohol decades earlier, according to Nikki Crowley, director of the Penn State Neuroscience Institute at University Park, Huck Early Career Chair in Neurobiology and Neural Engineering, assistant professor of biology in the Eberly College of Science, and the leader of the research team.

New Platform Overcomes Blood-Brain Barrier for Drug Delivery

Posted by in categories: biotech/medical, neuroscience

Summary: Researchers have developed a breakthrough system to deliver large therapeutic molecules into the brain, overcoming the challenges of the blood-brain barrier. The innovative blood-brain barrier-crossing conjugate (BCC) platform utilizes a biological process called γ-secretase-mediated transcytosis to safely transport drugs like oligonucleotides and proteins into the central nervous system via intravenous injection.

In mouse models and human brain tissue, the system effectively silenced harmful genes linked to diseases such as ALS and Alzheimer’s without causing significant side effects. This advancement could revolutionize treatments for neurological and psychiatric disorders, solving a critical challenge in brain research.
