“Consciousness” –Existing Beyond Matter, Or in the Central Nervous System as an Afterthought of Nature?

Posted by in categories: cosmology, mathematics, neuroscience

Does human consciousness exist separate from matter, or is it embodied in the body –a critical player in anything that has to do with mind? “We are not thinking machines that feel; rather, we are feeling machines that think.” answers neuroscientist Antonio Damasio, who pioneered the field of embodied consciousness –the bodily origins of our sense of self. “We may smile and the dog may wag the tail, but in essence,” he says. “we have a set program and those programs are similar across individuals in the species. There is no such thing as a disembodied mind.”

Consciousness is considered by leading scientists as the central unsolved mystery of the 21st Century: “I have a much easier time imagining how we understand the Big Bang than I have imagining how we can understand consciousness,” says Edward Witten, theoretical physicist at the Institute for Advanced Study in Princeton, New Jersey who has been compared to Isaac Newton and Einstein about the phenomena that has been described as assuming the role spacetime did before Einstein invented his theory of relativity.

Some scientists have asked how can we be sure that the source of consciousness lies within our bodies at all? One popular, if mystical, idea, writes astrophysicist Paul Davies in The Demon in the Machine, “is that flashes of mathematical inspiration can occur by the mathematician’s mind somehow ‘breaking through’ into a Platonic realm of mathematical forms and relationships that not only lies beyond the brain but beyond space and time altogether.”

Metformin Treatment Linked to Slowed Cognitive Decline

Posted by in categories: biotech/medical, neuroscience

Summary: Metformin, a drug commonly used to treat diabetes, slows cognitive decline and reduces dementia risk in older people with diabetes.

Report: Fewer Americans want to work from home

Posted by in categories: augmented reality, biotech/medical, business, neuroscience, virtual reality

Before #COVID19, we like to imagine a #future where we can get and do anything from home, including working, with the help of novel #technologies such as #VR and #AR.

However, the #COVID19 pandemic shows us the human nature, that is, “going out” is one of the basic needs for human being!

One revelation here is that: When speaking of how #technology can change our lives, we often neglect the humane factors and focus only on the technical ones. Take #VR as an example. Yes, it does allow you to have a shopping experience similar to (or even better than) shop outside. However, do you really want to stay at home 24/7 and complete everything online?

Neuroscience study finds ‘hidden’ thoughts in visual part of brain

Posted by in categories: information science, neuroscience

How much control do you have over your thoughts? What if you were specifically told not to think of something—like a pink elephant?

A recent study led by UNSW psychologists has mapped what happens in the brain when a person tries to suppress a . The neuroscientists managed to ‘decode’ the complex brain activity using functional brain imaging (called fMRI) and an imaging algorithm.

The findings suggest that even when a person succeeds in ignoring a thought, like the pink elephant, it can still exist in another part of the brain—without them being aware of it.

Scientists Discover Why We Need Sleep – “Important Work Is Being Done”

Posted by in categories: health, neuroscience

In very early life, sleep helps build the brain’s infrastructure, but it then takes on an entirely new decluttering role.

Prolonged sleep deprivation can lead to severe health problems in humans and other animals. But why is sleep so vital to our health? A UCLA-led team of scientists has answered this question and shown for the first time that a dramatic change in the purpose of sleep occurs at the age of about 2-and-a-half.

Before that age, the brain grows very rapidly. During REM sleep, when vivid dreams occur, the young brain is busy building and strengthening synapses — the structures that connect neurons to one another and allow them to communicate.

Study Shows How Fast Our Brains Are at ‘Recording’ New Words

Posted by in category: neuroscience

Summary: Cortical representations for the sounds and meanings of new words learned form within an hour or two following exposure.

Source: Skoltech

How much time does a brain need to learn a new word? A team of Skoltech researchers and their colleagues monitored changes in brain activity associated with learning new words and found that cortical representations of the sound and meaning of these words may form in just 1 to 2 hours after exposure without any night’s sleep consolidation, as earlier research suggested. This research has implications for diagnosing speech disorders and improving the efficiency of learning. The paper was published in the journal Frontiers in Neuroscience.

Quantum mechanics in the brain

Posted by in categories: computing, neuroscience, quantum physics

Does the enormous computing power of neurons mean consciousness can be explained within a purely neurobiological framework, or is there scope for quantum computation in the brain?

Common drugs linked to increased risk of Alzheimer’s

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

A new study suggests anticholinergic medications may increase the risk of accelerated cognitive decline, especially in older adults at high risk of developing Alzheimer’s disease.

Anticholinergic drugs block the action of acetylcholine, a chemical messenger that controls a range of automatic bodily functions and plays a vital role in memory and attention.

Doctors prescribe these drugs for a variety of conditions, including urinary incontinence, overactive bladder, chronic obstructive pulmonary disorder (COPD), seasonal allergies, and depression.

The brain-computer interface is coming, and we are so not ready for it

Posted by in categories: computing, law, neuroscience, physics, wearables

Are you ready?

“if you were the type of geek, growing up, who enjoyed taking apart mechanical things and putting them back together again, who had your own corner of the garage or the basement filled with electronics and parts of electronics that you endlessly reconfigured, who learned to solder before you could ride a bike, your dream job would be at the Intelligent Systems Center of the Applied Physics Laboratory at Johns Hopkins University. Housed in an indistinct, cream-colored building in a part of Maryland where you can still keep a horse in your back yard, the ISC so elevates geekdom that the first thing you see past the receptionist’s desk is a paradise for the kind of person who isn’t just thrilled by gadgets, but who is compelled to understand how they work.”
