Unconscious determinants of free decisions in the human brain

There has been a long controversy as to whether subjectively ‘free’ decisions are determined by brain activity ahead of time. We found that the outcome of a decision can be encoded in brain activity of prefrontal and parietal cortex up to 10 s before it enters awareness. This delay presumably reflects the operation of a network of high-level control areas that begin to prepare an upcoming decision long before it enters awareness.

Many choices seems promising until you actually have to choose

People faced with more options than they can effectively consider want to make a good decision, but feel they’re unable to do so, according to the results of a novel study from the University at Buffalo that used cardiovascular measures and fictional dating profiles to reach its conclusions.

The relationship between looking and listening and human emotions

A new study reveals the relationship between attentional state and emotions from pupillary reactions. Visual perception elicits emotions in all attentional states, while auditory perception elicits emotions only when attention is paid to sounds. Source: PlosOne  

‘Philosophy lab test’ finds objective vision impossible

Johns Hopkins University researchers who study the mind and brain used methods from cognitive science to test a long-standing philosophical question: Can people see the world objectively? Their answer is a flat no. Source: Jorge Morales el al., “Sustained representation of perspectival shape,” PNAS (2020).

The three clocks that make up our concept of time

Thanks to this particular study as well as the succeeding ones, we now know that there are three clocks that govern how we perceive “time” — the body clock, the solar clock, and the social clock. Source: JStor Daily

Gesture study showed that our body language can be heard

Even without seeing the messenger, we can pick up each other’s body language, say researchers. Source: Technology Networks

World-first Artificial Neurons Created To Fight Chronic Diseases

Artificial neurons on silicon chips that behave just like the real thing have been invented by scientists – a first-of-its-kind achievement with enormous scope for medical devices to cure chronic diseases, such as heart failure, Alzheimer’s, and other diseases of neuronal degeneration. Critically the artificial neurons not only behave just like biological neurons but only need one billionth the power of a microprocessor, making them ideally suited for use in medical implants and other bio-electronic devices.

“Tatoo electrodes” can now be used to measure brain activity

The new tattoo electrodes are the very first dry electrode type that is suitable for long-term EEG measurements and at the same time compatible with magneto-encephalography (MEG). MEG is a well-established method for monitoring brain activity, for which so far only so-called “wet electrodes” can be used. Such electrodes work on the basis of electrolyte, gel or an electrode paste, and thus dry out quickly and are unsuitable for long-term measurements. Source: Technology Networks

People May Know the Best Decision – and Not Make It

When faced with a decision, people may know which choice gives them the best chance of success, but still take the other option, a new study suggests. Source: Technology Networks
