Plasticity: A network theory
“Plasticity in mental health: A network theory“ Plasticity is the ability to modify brain and behavior, ultimately promoting an amplification of the impact of the context on the individual’s mental health. Thus, plasticity is not beneficial per se but its value depends on contextual factors, such as the quality of the living environment. High plasticity is…

Top-down and bottom-up neuroscience
“Top-down and bottom-up neuroscience: overcoming the clash of research cultures“ As scientists, we want solid answers, but we also want to answer questions that matter. Yet, the brain’s complexity forces trade-offs between these desiderata, bringing about two distinct research approaches in neuroscience that we describe as ‘top-down’ and ‘bottom-up’. Bottom-up neuroscience The bottom-up research culture…

Therapy That Isn’t Psychotherapy
I found this nice discours on an interesting topic, related with individual challlenges, AI and related tools appearing in this relation. Therapy That Isn’t Psychotherapy by Steven Reidbord Reducing the problem to a merely external one leads to therapy that resembles political advocacy; therapy that prizes agreement (“validation”) over all else; therapy that absolves the patient…

Resilience phenotypes derived from an active inference account of allostasis
“Resilience phenotypes derived from an active inference account of allostasis“:Within a theoretical framework of enactive allostasis, we explore active inference strategies for minimizing surprise to achieve resilience in dynamic environments. While individual differences and extrinsic protective factors traditionally account for variability in resilience trajectories following stressor exposure, the enactive model emphasizes the importance of the…

Top-down influences
“Top-down influences on the perception of emotional stimuli” (also available as PDF) The ability to quickly and accurately perceive external emotional stimuli — events in the environment that evoke changes in feelings, physiology and behaviour — is vital for adaptive social interactions and effective decision making in everyday life. Contemporary theories of emotional perception emphasize the influence of top-down…

Blink and you see it
“Blink and you see it“ Every few seconds, our visual world disappears behind a thin fold of skin that maintains the tear film on the corneal surface and, for more than a tenth of a second, blocks light from falling onto the retina. “Blink and you miss it” is a common idiom that captures how…

Defining intelligence: Bridging the gap
“Defining intelligence: Bridging the gap between human and artificial perspectives“ Achieving a widely accepted definition of human intelligence has been challenging, a situation mirrored by the diverse definitions of artificial intelligence in computer science. By critically examining published definitions, highlighting both consistencies and inconsistencies, this paper proposes a refined nomenclature that harmonizes conceptualizations across the two disciplines.…

The unbearable slowness of being …
The unbearable slowness of being: Why do we live at 10 bits/s? This article is about the neural conundrum behind the slowness of human behavior. The information throughput of a human being is about 10 bits/s. In comparison, our sensory systems gather data at ∼109 bits/s. The stark contrast between these numbers remains unexplained and touches…
