Beauty and the brain

Posted by in category: neuroscience

How our brains view beauty is also from heredity.


British neurobiologist Semir Zeki says human brains work alike and we have a shared inheritance in the way we perceive beauty Who do you think is beautiful? Apparently all our votes would more or less go to the same person. Wherever we are from in the world, man or woman, Indian or South American, the way we experience beauty is pretty much the same. Because our brains work similarly, and as humans, we have a shared inheritance. Listening to British neurobiologist Semir Zeki is sure to leave one mesmerised about our understanding of the way our brains work.

Zeki, a frontrunner in the fairly nascent field of neuro-aesthetics, was in Bengaluru recently for the British Council’s lecture series “Science and Beyond”. A professor of neuro-aesthetics at the University College London, Zeki specialises in studying the primate visual brain, neural correlates of the experience of love, desire, beauty, within the field of neuro-aesthetics. In his award-winning study conducted across people of various races and cultures, the question he addressed was ‘What are the neural mechanisms that are engaged when you experience beauty?’. “I have not asked anything about the concept of beauty, the nature of beauty or anything like that. All I can tell you is that when you experience beauty, regardless of the source – whether it is visual, musical or mathematical, its correlated activity is in the same part of the brain.

This VR Company Helps Soldiers Cope With War Injuries

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

MindMaze has received $100 million to further medical research and launch a VR gaming system.

For a soldier who has endured an amputation, severe phantom limb pain can be debilitating.

Virtual reality company MindMaze has designed a medical virtual reality, augmented reality, and motion capture video game system that immerses the amputee in a virtual environment, where moving the existing arm will move the non-existing arm of the avatar. Neuroscientist and MindMaze founder and CEO Tej Tadi says this “mirroring” tricks the brain into believing the severed limb is actually there, and has proven benefits in phantom pain management.

Terence Mckenna’s ‘cyberdelic’ predictions for Virtual Reality 25 years on

Posted by in categories: computing, cyborgs, life extension, neuroscience, transhumanism, virtual reality

Cannot wait to hear Mckenna’s perspective on BMIs for brain connection to all things digital, and microbots used to extend life as well as bionic body parts.


Famed psychonaut Terence Mckenna envisioned a very radical approach of bridging psychedelics with virtual reality to create a supercharged version of consciousness in which language, or rather the meaning behind what we speak, could be made visual in front of our very eyes.

In Mckenna’s “cyberdelic” future of virtual reality, artists and the revival of art, would be at the forefront of innovation, according to a talk he gave to a German audience in 1991.

Virtual reality treatment helps depression patients in study

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

Here is a concept; “could VR be used to rehabilitate criminals to experience through VR what their victims have experienced?” I do know in the recent 20 yrs a part of rehabilitation has included the criminal facing their victims so that the criminal develops a new level of empathy. However, could VR be a better solution? And, should it be?


LONDON, Feb. 15 (UPI) — Depression patients who interacted with characters in a virtual reality environment were less critical and more compassionate toward themselves, researchers found in a small study in England.

Researchers at University College London found some of the self-directed negativity of people feel in depression can be mitigated through role-playing in virtual reality.

Depression Treatment: Virtual Reality A New Therapy To Reduce Depressive Symptoms

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

People may soon use virtual reality to treat their depression and to be less critical and more compassionate towards themselves, a new study shows. A new virtual reality therapy has effectively reduced depressive symptoms of patients with some reporting significant drop in depression severity.

In the study, published in the British Journal of Psychiatry Open, patients claim virtual reality therapy changed their response to real-life situations in which they would previously have been self-critical.

The findings come from the analysis of the effect of the therapy to 15 depression patients, aged 23 to 61. Researchers, from University College London (UCL) and ICREA-University of Barcelona, asked the participants to wear a virtual reality headset to see from the perspective of a life-size “avatar” or virtual body.

Ground Zero for Alzheimer’s Disease found at base of brainstem

Posted by in categories: biotech/medical, neuroscience

Very interesting since many complex neural diseases also have ties to the brain stem such as Dystonia.


Feb. 22, 2016 — There is a new ground zero for Alzheimer’s Disease, according to a new discovery of a critical but vulnerable region in the brain that appears to be the first place affected by late onset Alzheimer’s disease. It also may be more important for maintaining cognitive function in later life than previously appreciated.

The locus coeruleus is a small, bluish part of the brainstem that releases norepinephrine, the neurotransmitter responsible for regulating heart rate, attention, memory, and cognition. Its cells, or neurons, send branch-like axons throughout much of the brain and help regulate blood vessel activity, says a new review of the scientific literature.
