Evaluating functional brain organization in individuals and identifying contributions to network overlap

Posted by in categories: biotech/medical, neuroscience


Abstract. Individual differences in the spatial organization of resting-state networks have received increased attention in recent years. Measures of individual-specific spatial organization of brain networks and overlapping network organization have been linked to important behavioral and clinical traits and are therefore potential biomarker targets for personalized psychiatry approaches. To better understand individual-specific spatial brain organization, this paper addressed three key goals. First, we determined whether it is possible to reliably estimate weighted (non-binarized) resting-state network maps using data from only a single individual, while also maintaining maximum spatial correspondence across individuals. Second, we determined the degree of spatial overlap between distinct networks, using test-retest and twin data.

Prioritizing Brain Health: Preventing Cognitive Decline

Posted by in categories: life extension, neuroscience

In this episode of the Lifespan podcast, Dr. David Sinclair and co-host Matthew LaPlante dissect the topic of brain aging. They explore evidence suggesting that the brain ages more slowly than other parts of the body and highlight how cognitive function is impacted by aging. Different interventions aimed at preserving brain health are also discussed, including a plant-based diet, exercise, metformin, NAD boosters, and sufficienh #Wellness #DavidSinclair #Longevity #BrainHealth #Healthspan

Diamond quantum sensors measure neuron activity

Posted by in categories: biotech/medical, neuroscience, quantum physics

A recent study by European scientists shows that highly sensitive sensors based on color centers in a diamond can be used to record electrical activity from neurons in living brain tissue. The work is published in the journal Scientific Reports.

Before people encounter symptoms of diseases such as dementia, slight changes have usually occurred already in the . It may be that parts of the brain are swelling up or clumps of proteins are forming. These small changes might influence how in the brain signal each other and communicate, how information is processed and memorized.

Medical scientists want to study these minor changes that occur in the very early stages of a disease. That way, the intention is to learn more about the causes of the disease to provide new insights and more efficient treatments. Today, microscopic studies on the brain are performed with one of two strategies: Optical inspection of brain tissue samples from animals or deceased patients that suffer from the studied disease or measurements of the signals from the nerve cells using wires, coloring, or light.

Brain implants revive cognitive abilities long after traumatic brain injury

Posted by in categories: biotech/medical, neuroscience

The results of the clinical trial were published Dec. 4 in Nature Medicine.

More than 5 million Americans live with the lasting effects of moderate to severe traumatic brain injury — difficulty focusing, remembering and making decisions. Though many recover enough to live independently, their impairments prevent them from returning to school or work and from resuming their social lives.

Brain Area Associated With Impulse Control Discovered

Posted by in categories: biotech/medical, neuroscience

Summary: A new study identified the right inferior frontal gyrus (rIFG) as a central regulator in the brain’s inhibitory control circuit.

Using dynamic causal modeling and fMRI on a sample of 250 participants, the study reveals that the rIFG significantly influences the caudate nucleus and thalamus during response inhibition tasks. This research also shows gender differences in brain function: women have distinct neural patterns in the thalamus, and overall, better inhibitory control correlates with stronger neural communication from the thalamus to the rIFG.

These findings provide valuable insights for developing neuromodulation therapies for mental and neurological disorders with inhibitory control deficits.

Using Generative AI As An Interactive Rage-Room Chatbot Raises Mental Health Guidance Qualms

Posted by in categories: neuroscience, robotics/AI

In today’s column, I am continuing my ongoing series that has closely been exploring the use of generative AI as a generalized interactive chatbot that imparts mental health guidance.


But serious and sobering qualms exist. There isn’t a pre-check to validate that someone ought to be resorting to generic generative AI for such advisement. There isn’t any ironclad certification of the generative AI for use in this specific capacity. The guardrails of the generative AI might not be sufficient to avoid professing ill-advised guidance. So-called AI hallucinations can arise (as an aside, the parlance “AI hallucination” terminology is something that I demonstrably disfavor as a phraseology, for the reasons stated at the link here, but anyway generally connotes that generative AI can produce specious or fabricated answers). And so on.

All in all, you might declare that we are immersed in the Wild West of AI-based human mental health advisement, which is taking place surreptitiously yet in plain sight, and lacks the traditional kinds of checks and balances that society expects to protectively be instilled.

Optimizing Health with Light: Sunlight, Blue Light & Red Light

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

I describe the mechanisms by which different wavelengths of light impact the cells, tissues and organs of the human body, and how specifically timed light exposure of specific wavelengths can be used to improve sleep, enhance alertness, modulate hormone levels, and improve mood. I also explain the use of ultraviolet and infrared phototherapies to relieve pain increase testosterone and estrogen levels; improve skin health, appearance and wound healing; and how red light can be used to offset age-related vision loss and provide neuroprotection. Throughout the episode, I describe the mechanisms of light-based therapies and actionable tools that people can use positively impact mental and physical health.

The Evolutionary Psychology Of Love

Posted by in categories: evolution, neuroscience, sex

Robin Dunbar is an anthropologist, evolutionary psychologist, head of the Social and Evolutionary Neuroscience Research Group at the University of Oxford and an author. Love is something that people have been trying to describe for thousands of years. Beyond asking what love is, is the question of why humans feel something so strange in the first place. Why would evolution have exposed us to this extreme sensation with huge potential for catastrophe and pain? Expect to learn how love is adaptive, why humans need to have more sex than almost all other animals to get pregnant, why ancestral men who hunted big animals were only doing it to get laid, how the length of your fingers can tell you how promiscuous you are, whether Robin thinks humans were ancestrally monogamous and much more…
