The computational power of the human brain
Peter J. Gebicke-Haerter published a great review article with this title. I selected some snippets and the key conclusion: At the end of the 20th century, analog systems in computer science have been widely replaced by digital systems due to their higher computing power. Nevertheless, the question keeps being intriguing until now: is the brain…

Harris Hawks Optimization
The Harris hawk optimizer is a recent population-based metaheuristics algorithm that simulates the hunting behavior of hawks. This swarm-based optimizer performs the optimization procedure using a novel way of exploration and exploitation and the multiphases of search. A review research focuses on the applications and developments of the recent well-established robust optimizer Harris hawk optimizer…

Wicked7 – looking for “Regenerative” solution
12 jul 2022, TedX@Athens. Christian Sarkar makes bold statements: Globalization has failed. Income inequality has exploded. COVID hasn’t disappeared yet. And War is at the gate. What can be done in your neighborhood, in your city? We learn the lessons of regeneration from Palermo, Sicily – and the (website and) book by Christian Sarkar, Philip…

A top-down, bottom-up model of circuit function for anxiety and depression.
A great review article describes the bottom-up and top-down processing from Marr’s computational-algorithmic-implementation perspective to understand depressive and anxious disease states. The review illustrate examples of bottom-up processing as basolateral amygdala signaling and projections and top-down processing as medial prefrontal cortex internal signaling and projections. Understanding these internal processing dynamics can help us better model…

AI can distort human beliefs
Without a zone of uncertainty plus other troubling features, generative AI is poised to amplify bias and falsehoods, distort human perception. Individual humans form their beliefs by sampling a small subset of the available data in the world. Once those beliefs are formed with high certainty, they can become stubborn to revise. Fabrication and bias…

Social and Affective Neuroscience of Everyday Human Interaction
I found – rather serendipitous – this recent, open access and very interesting book “Social and Affective Neuroscience of Everyday Human Interaction“, edited by Springer 2023. This Open Access book presents the current state of the art knowledge on social and affective neuroscience based on empirical findings. Some highlights as appetiser: Molecular Imaging of the…
