A dive into the black waters under the surface of persuasive design

A dive into the black waters under the surface of persuasive design

A Guardian article last October brings the darker aspects of the attention economy, particularly the techniques and tools of neural hijacking, into sharp focus. The piece summarizes some interaction design principles and trends that signal a fundamental shift in means, deployment, and startling effectiveness of mass persuasion. The mechanisms reliably and efficiently leverage neural reward (dopamine) circuits to seize, hold, and direct attention toward whatever end the designer and content providers choose. The organizer of a $1,700 per person event…

Does quantum mechanics play a role in consciousness

Does quantum mechanics play a role in consciousness

A 2017 BBC article concisely reviews essential concepts of quantum physics and summarizes the state of scientific speculation into the possible interactions of consciousness and quantum mechanics. Of interest are some specific, possibly testable, suggestions about chemical structures that could sustain nuclear spin entanglements in the brain for up to two days.

Neural responses to media a strong predictor of friendship

Neural responses to media a strong predictor of friendship

“The findings revealed that neural response similarity was strongest among friends, and this pattern appeared to manifest across brain regions involved in emotional responding, directing one’s attention and high-level reasoning. Even when the researchers controlled for variables, including left-handed- or right-handedness, age, gender, ethnicity, and nationality, the similarity in neural activity among friends was still evident. The team also found that fMRI response similarities could be used to predict not only if a pair were friends but also the social distance between…

Wild systems theory (WST) – context and relationships make reality meaningful

Wild systems theory (WST) – context and relationships make reality meaningful

Edward has posted some great thoughts and resources on embodied cognition (EC). I stumbled on some interesting information on a line of thinking within the EC literature. I find contextualist, connectivist approaches compelling in their ability to address complex-systems such as life and (possibly) consciousness. Wild systems theory (WST) “conceptualizes organisms as multi-scale self-sustaining embodiments of the phylogenetic, cultural, social, and developmental contexts in which they emerged and in which they sustain themselves. Such self-sustaining embodiments of context are naturally and necessarily…

Neuroscience of Empathy

Neuroscience of Empathy

(This is copied from the Meetup site. Thanks again to Brent for hosting.) Details Empathy is the ability to put yourself in another person’s shoes and understand how they feel- to be them, even for a second. It’s the link between self and others: how we connect, heal, and relate. Considering its importance in every aspect of our lives, we are taking a deeper look at the neuroscience behind empathy. Recommended Preparation Info. The Neuroscience of Empathy | Article |…

Downward mental causation and free will

Downward mental causation and free will

I know, to free will or not to free will, that is the hackneyed question debated in philosophical circles since we learned how to talk. But here’s a cognitive neuroscientist’s research on “how neuronal code underlies top-down mental causation.” It’s a long video, over 2 hours, and I have yet to complete it. Here is Peter Tse’s CV.  Here is his book on the topic is. Here is a good summary of Tse’s work on the topic.

Future discussion topic recommendations

Future discussion topic recommendations

Several of us met on Labor Day with the goal of identifying topics for at least five future monthly meetings. (Thanks, Dave N, for hosting!) Being the overachievers we are, we pushed beyond the goal. Following are the resulting topics, which will each have its own article on this site where we can begin organizing references for the discussion: sex-related influences on emotional memory gross and subtle brain differences (e.g., “walls of the third ventricle – sexual nuclei”) “Are there…

Brain’s facial-recognition mechanism revealed

Brain’s facial-recognition mechanism revealed

Caltech researchers have identified the brain mechanisms that enable primates to quickly identify specific faces. In a feat of efficiency, surprisingly few feature-recognition neurons are involved in a process that may be able to distinguish among billions of faces. Each neuron in the facial-recognition system specializes in noticing one feature, such as the width of the part in the observed person’s hair. If the person is bald or has no part, the part-width-recognizing neuron remains silent. A small number of…

Mathematical field of topology reveals importance of ‘holes in brain’

Mathematical field of topology reveals importance of ‘holes in brain’

New Scientist article: Applying the mathematical field of topology to brain science suggests gaps in densely connected brain regions serve essential cognitive functions. Newly discovered densely connected neural groups are characterized by a gap in the center, with one edge of the ring (cycle) being very thin. It’s speculated that this architecture evolved to enable the brain to better time and sequence the integration of information from different functional areas into a coherent pattern. Aspects of the findings appear to…
