A personal testimony to neuroplasticity

A personal testimony to neuroplasticity

A member of one of my online writing communities posted this interesting personal article on his recovery following a serious concussion. This quick read illustrates the subjective experience of being aware your brain is malfunctioning and witnessing recovery from the inside.

Next discussion meeting Apr 2: Brain-Computer Interface, now and future

Next discussion meeting Apr 2: Brain-Computer Interface, now and future

During our next discussion meeting, we’ll explore the status, future potential, and human implications of neuroprostheses–particularly brain-computer interfaces. If you are local to Albuquerque, check our Meetup announcement to join or RSVP. The announcement text follows. Focal questions What are neuroprostheses? How are they used now and what may the future hold for technology-enhanced sensation, motor control, communications, cognition, and other human processes? Resources (please review before the meeting) Primary resources • New Brain-Computer Interface Technology (video, 18 m) https://www.youtube.com/watch?v=CgFzmE2fGXA • Imagining…

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…

Cognitive decline as early as 18 years prior to clinical diagnosis of dementia

Cognitive decline as early as 18 years prior to clinical diagnosis of dementia

Performance on individual cognitive tests of episodic memory, executive function, and global cognition also significantly predicted the development of AD dementia, with associations exhibiting a similar trend over 18 years. Conclusions: Our findings suggest that cognitive impairment may manifest in the preclinical phase of AD dementia substantially earlier than previously established. http://www.neurology.org/content/85/10/898 (paywall site)

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…

Is a carb-free diet good for brain function?

Is a carb-free diet good for brain function?

An article in Wired cites two studies that show carb-free diets improved the memories and extended the lives of lab mice. While there are many DIY human experiments underway, scientific trials are needed to clarify the effects of ketogenic diets on people.

Computer metaphor not accurate for brain’s embodied cognition

Computer metaphor not accurate for brain’s embodied cognition

It’s common for brain functions to be described in terms of digital computing, but this metaphor does not hold up in brain research. Unlike computers, in which hardware and software are separate, organic brains’ structures embody memories and brain functions. Form and function are entangled. Rather than finding brains to work like computers, we are beginning to design computers–artificial intelligence systems–to work more like brains.  https://www.wired.com/story/tech-metaphors-are-holding-back-brain-research/ 

People’s brains store and recall stories the same way

People’s brains store and recall stories the same way

New scientific findings support the idea that different humans’ brains store and recall story scenes the same way, rather than each person developing unique memory patterns about stories. Also, people generally do well recalling the details of stories. I want to see more targeted research that determines whether information packed in story structures (a person wrestling with a difficult challenge and changing as a result) is more readily and accurately transmitted from brain to brain via storytelling. This would be…
