New Ways to Nudge the Brain


New neurostimulation technology works safely and non-invasively to modify brain activity. The findings may provide some foundational knowledge for the development of future technologies that could expedite cognitive processes. Source: Neuroscience News

Here’s What You Can Learn About Architecture from Tracking People’s Eye Movements


While many architects have long clung to the old “form follows function” adage, form follows brain function might be the motto of today’s advertisers and automakers, who increasingly use high-tech tools to understand hidden human behaviors, and then design their products to meet them (without ever asking our permission!).

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  

“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

In a First, Patient Controls Two Prosthetic Arms with His Thoughts


Researchers have, for the first time, demonstrated simultaneous control of two of the world’s most advanced prosthetic limbs through a brain-machine interface. The team is also developing strategies for providing sensory feedback for both hands at the same time using neural stimulation. (Source: Neuroscience News, Oct 18, 2019)

Social Synchronization in the EEG


Humans operate within a social context.  The study of social synchronization or ‘hyperscanning’ using EEG  is beginning to reveal insight into human interactions. (Source: Jennifer J Newson, SapienLabs)

The Fantastical Claims of Consumer Brain Wearables


Consumer brain recording technologies make all sorts of claims that are simply not substantiated in the literature at the level of individual predictions. (Source: Tara Thiagarajan, SapienLabs)  

Brain marker for angry dreams


People with greater frontal alpha asymmetry are less able to regulate strong, emotional, affective states, such as anger, in their dreams. Researchers have identified a pattern of brain activity that predicts anger experienced during dreaming, according to a new study of healthy adults published in Journal of Neuroscience.

Gaze bias


In research using eye tracking, it was found that gaze was a good indication of subsequent choice. The research suggests that orienting and preference for objects in general are intrinsically linked in a positive feedback loop leading to the conscious choice. Shimojo, S., Simion, C., Shimojo, E., & Scheier, C. (2003). Gaze bias both reflects and influences preference. Nature Neuroscience, 6(12), 1317–1322.

Marketing Lessons from Eye-Tracking Studies


Eye-tracking software and heat maps can reveal some startling insights into increasing conversions (and avoiding sales killers) on both websites and print media that can be of benefit to marketers. Read about 7 marketing lessons that were confirmed by eye tracking studies on Neil Patel’s blog. Read more.
