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.

GSR


Galvanic skin response or GSR allows the researcher to tap into unconscious behaviour. With GSR, it is possible to access and measure involuntary unconscious behavior. This makes GSR highly suitable for exploring emotional arousal that is not censored through language, culture and rational thought. Source: IMotions. (2017). GSR Pocket Guide. iMotions.

Pupillometry


Emotions such as heightened arousal can make pupils dilate. Belladonna (or deadly  nightshade) was once used by women to dilate their pupils, thus making them seemingly more attractive.
