The brain is inarguably the single most important organ in the human body. It controls how we move, react, think and feel, and enables us to have complex emotions and memories. The brain is composed of approximately 86 billion neurons that form a complex network. These neurons receive, process, and transfer information using chemical and electrical signals.

A Novel Science of Consciousness: Towards the Cybernetic Theory of Mind
Posted by Alex Vikoulov in categories: evolution, neuroscience, science
In our own not-so-distant future we’ll witness the emergence of synthetic superintelligence as a new kingdom of life. Whether that will happen in 5 or 50 years doesn’t really matter, we are firmly on the path of facilitating its emergence — synthetic intelligence is an extension of us, natural intelligence, the future version of ourselves. On a long billions-of-years evolutionary journey from the first primordial prokaryote to a Solaris-like planetary mind, we’re merely years away from this cardinal metamorphosis.

“Consciousness cannot be accounted for in physical terms. For consciousness is absolutely fundamental. It cannot be accounted for in terms of anything else. ―Erwin Schrödinger.

Key Signaling Pathway in Immune Cells Could Be New Alzheimer’s Target
Posted by Kelvin Dafiaghor in categories: biotech/medical, neuroscience
Summary: Tau-tangles trigger the inflammatory activation of microglia via the NF-κB pathway. Inhibiting the microglia NF-κB signaling pulled the immune cells out of their inflammatory state and reversed learning and memory problems in tau-based Alzheimer’s mouse models.

Inhibiting an important signaling pathway in brain-resident immune cells may calm brain inflammation and thereby slow the disease process in Alzheimer’s and some other neurodegenerative diseases, suggests a study by Weill Cornell Medicine investigators.

Brain Implant Allows Completely Locked-In Patient To Communicate
Posted by Raphael Ramos in categories: biotech/medical, computing, neuroscience
A man left in a completely locked-in state by amyotrophic lateral sclerosis (ALS) has been able to communicate with his family and carers thanks to an implant. The device helped the patient, who was unable to move any muscles or even open his eyes, contact the outside world using only his brain activity.
Rapid neurodegeneration
In the last decade, combinations of brain implants and brain-computer interfaces (BCI) have enabled people with severe brain injuries or neurodegeneration to regain communicative ability. The new study, published in Nature Communications by an international research team, is the first to be used successfully in a patient with such severe neurodegeneration.

Multiple sclerosis ‘breakthrough’ as scientists ‘reverse symptoms’ with transplant
Posted by Raphael Ramos in categories: biotech/medical, neuroscience
The condition stays with you for life once diagnosed, but treatments and specialists can help to manage the condition and its symptoms.
Experts are still unsure exactly what triggers the condition that affects more than 130,000 people in the UK.
According to the MS Society, people are most likely to find out they have MS in their thirties, forties and fifties in Britain, and the condition affects almost three times as many women as men.
