Algorithm brings whole-brain simulation within reach

Algorithm brings whole-brain simulation within reach

Comments 0 Comment

An improvement to the Neural Simulation Tool (NEST) algorithm, the primary tool of the Human Brain Project, expanded the scope of brain neural data management (for simulations) from the current 1% of discrete neurons (about the number in the cerebellum) to 10%. The NEST algorithm can scale to store 100% of BCI-derived or simulated neural data within near-term reach as supercomputing capacity increases. The algorithm achieves its massive efficiency boost by eliminating the need to explicitly store as much data…

Recording data from one million neurons in real time

Recording data from one million neurons in real time

Comments 0 Comment

Given the human brain’s approximately 80 billion neurons, it would take tens of thousands of these devices to record a substantial volume of neuron-level activities. Still, this is a remarkable achievement. The system would simultaneously acquire data from more than 1 million neurons in real time. It would convert the spike data (using bit encoding) and send it via an effective communication format for processing and storage on conventional computer systems. It would also provide feedback to a subject in…

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

Comments 0 Comment

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…

Query on interest in concept mapping

Query on interest in concept mapping

Comments 0 Comment

I like using concept maps to organize my thoughts and to plan articles and projects. I would like to share member-editable concept maps through this website. I’ve used the free Cmap Tools program for many years. Unfortunately, Cmap Tools is developed on the Java platform and I have been unable to get it to work on my Mac for about two years. (Apparently, it needs an older version of the Java Runtime Environment and several other tools I use need a…

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

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

Comments 0 Comment

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

Comments 0 Comment

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

Comments 1 comment

“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…
