Tactile stimulation improved motor performance, reduced phosphorylated tau, preserved neurons and synapses, and reduced DNA

DNA, or deoxyribonucleic acid, is a molecule composed of two long strands of nucleotides that coil around each other to form a double helix. It is the hereditary material in humans and almost all other organisms that carries genetic instructions for development, functioning, growth, and reproduction. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Summary: The neuroscience of consciousness explores the fundamental aspect of wakefulness and the higher-level cognitive perceptions, such as thinking and understanding.

Various theories, like the Global Neuronal Workspace Theory and the Integrated Information Theory, attempt to provide an explanatory framework for the conscious experience.

Scientists hope the findings could lead to treatments for the memory-destroying disease.

Researchers at Stanford University have developed digital skin that can convert sensations such as heat and pressure to electrical signals that can be read by electrodes implanted in the human brain.

Although such capability was developed years earlier, the components required at that time to convert digital signals were rigid and unwieldy.

This new e-skin is soft as, well, skin. The conversion elements are seamlessly incorporated within the skin, which measures a few tens of nanometers thick.

Perhaps the most intriguing evidence of consciousness in early infancy comes from a study conducted by Julia Moser at the University of Tübingen. Moser and her colleagues used second-order (“global”) auditory oddballs to probe for consciousness. Consider a sequence of tones that are clustered together into four groups of four tones, where each tone is either high pitched or low pitched. In the global oddball paradigm, the final tone in the first three groups differs from the preceding three tones (for example, if they are low then it will be high), but the final member of the last group will be identical to the preceding three tones (for example, they might all be low tones). In this scenario, the final tone is not an oddball (that is, outlier) relative to the preceding three tones, but it is an oddball relative to the entire sequence, for anyone who hears the three earlier groups of tones will expect the final member of this group to be an oddball.

Earlier research has suggested that the brain produces a distinctive response to second-order oddballs, which can be roughly thought of as a neural marker of surprise. Further, there is some evidence that this response is produced only when an individual is conscious. Using fetal magnetoencephalography (MEG), Moser and her team discovered that a version of this response could be found not only in newborns but also in 35-week-old fetuses. Again, this result does not provide proof of perceptual awareness in early infancy (let alone in utero), but it is yet another illustration of how neuroscience is beginning to pull back the curtain on infant experience.

Language impairment is comorbid in most children with Autism Spectrum Disorder (ASD) but its neural basis is poorly understood. Using structural magnetic resonance imaging (MRI), the present study provides the whole-brain comparison of both volume-and surface-based characteristics between groups of children with and without ASD and investigates the relationships between these characteristics in language-related areas and the language abilities of children with ASD measured with standardized tools. A total of 36 school-aged children participated in the study: 18 children with ASD and 18 age-and sex-matched typically developing controls. The results revealed that multiple regions differed between groups of children in gray matter volume, gray matter thickness, gyrification, and cortical complexity (fractal dimension).

Researchers hope the new app can help bridge the gap between supply and demand for mental health support.

Asking an AI chatbot to give a rundown on Napoleonic wars is fine. But using a chatbot service for a therapy session?

Even ChatGPT suggests going to a traditional mental health practitioner when you pour your heart out to the AI – perhaps because the most important element of therapy is the client-therapist relationship.

Ago when I was a kid in college my friend Eric got me into many things. We played music together and used a Kurzweil Keyboard, and a bunch of weird stuff. We had an ADAT hooked up to the Kurzweil with fiber optic cables. I had Roland keyboards & Drum machines but I loved the Kurzweil. He started teaching me many things because he was really smart. I was studying psychology so he loaned me his DSMIV and books on Industrial Organiza… See more.

A bit long, but a good read. About 20 years ago when I was a kid in college my friend Eric got me into many things. We played music together and used a Kurzweil Keyboard, and a bunch of weird stuff. We had an ADAT hooked up to the Kurzweil with fiber optic cables. I had Roland keyboards & Drum machines but I loved the Kurzweil. He started teaching me many things because he was really smart. I was studying psychology so he loaned me his DSMIV and books on Industrial Organizational Psychology. He then told me about other books like “Society of Mind”(Marvin Minsky), “Age of Intelligent Machine” (Ray Kurzweil), Engines of Creation (K Eric Drexler), of course Richard Feynman, and many more. I dreamed of that technology and kept reading more. In the 2000’s Drexler and Feynman’s visions became a paradign and applications started rolling out, and now nanotechnology is applied to most everything we know. We are now at the second paradigm where we see the visions of Minsky/McCarthy, Kurzweil and others becoming easily available applications. As a Child I watched the Jetsons & Srar Trek and now with flying cars it’s not if, but when. Space travel is already here. All these technologies will transform global societies, but we must all focus on investing more in the advancement of society than the destruction of it. Many of the things we now invision in our minds we may see in 10 years. People think saving your consciousness & longevity is impossible, but I don’t. Some even thought that regenerating tissue and organs is impossible, but we can do that now. Now people keep saying, “This ancient turtle died, this rhino died (I hear that all the time in Kenya), this elephant died, but I say okay it’s not cool, but what can we salvage from it to bring the species back with advances in technology later? Do we use cryogenics? How do we save the genetic material? Technology can be used in so many ways. Every Day Lifeboat posts feats many do not know. If more people on earth had such a focus, as opposed to dumbed down entertainment like The Kardashians for instance, we would be living in a much better world with more people proposing more ideas and collaborations. I always say we are moving in the wrong way in the evolutionary process, and it is a bit telling that some phones are smarter than many people. I you add ChatGPT. We have so much advanced technology and science, yet we can’t even fight cancer. It took decades for people to learn the importance of diet in HIV treatment. However, Ray Kurzweil has for decades talked about the importance of diet for longevity. Just the other day it was published that processed foods affect cognitive function. Before that it was released processed foods cause cancer. We must change, and go in the right way of evolution to the Singularity another paradigm shift and cooperarion, instead of backwards to a barbaric age of conflict and greed. Always share your knowledge and I thank all who do share in this group. More should share as well, and Lifeboat should use more platforms to reach more people.

Evidence that non-invasive sensory stimulation of 40 Hz gamma frequency brain rhythms can reduce Alzheimer’s disease pathology and symptoms, already shown with light and sound by multiple research groups in mice and humans, now extends to tactile stimulation. A new study by MIT scientists shows that Alzheimer’s model mice exposed to 40 Hz vibration an hour a day for several weeks showed improved brain health and motor function compared to untreated controls.

The MIT group is not the first to show that gamma frequency tactile stimulation can affect brain activity and improve motor function, but they are the first to show that the stimulation can also reduce levels of the hallmark Alzheimer’s protein phosphorylated tau, keep neurons from dying or losing their synapse circuit connections, and reduce neural DNA damage.

“This work demonstrates a third sensory modality that we can use to increase gamma power in the brain,” said Li-Huei Tsai, corresponding author of the study, director of The Picower Institute for Learning and Memory and the Aging Brain Initiative at MIT, and Picower Professor in the Department of Brain and Cognitive Sciences (BCS).
