Newly discovered form of interneural communication

Newly discovered form of interneural communication

Two independent teams of scientists from the University of Utah and the University of Massachusetts Medical School have discovered that a gene crucial for learning, called Arc, can send its genetic material from one neuron to another by employing a strategy commonly used by viruses. The studies, both published in Cell, unveil a new way that nervous system cells interact. https://www.nih.gov/news-events/news-releases/memory-gene-goes-viral

Can tai chi and qigong postures shape our mood?

Can tai chi and qigong postures shape our mood?

Subtitle: “Toward an embodied cognition framework for mind-body research,” by Osypiuk et al. in Frontiers in Human Neuroscience, May 1, 2018. The abstract: “Dynamic and static body postures are a defining characteristic of mind-body practices such as Tai Chi and Qigong (TCQ). A growing body of evidence supports the hypothesis that TCQ may be beneficial for psychological health, including management and prevention of depression and anxiety. Although a variety of causal factors have been identified as potential mediators of such…

Consciousness Regained:

Consciousness Regained:

“Disentangling mechanisms, brain systems, and behavioral responses” by Johan F. Storm et al., Journal of Neuroscience 8 November 2017, 37 (45) 10882-10893. The abstract: “How consciousness (experience) arises from and relates to material brain processes (the “mind-body problem”) has been pondered by thinkers for centuries, and is regarded as among the deepest unsolved problems in science, with wide-ranging theoretical, clinical, and ethical implications. Until the last few decades, this was largely seen as a philosophical topic, but not widely accepted…

Neuroscience of Consciousness Journal

Neuroscience of Consciousness Journal

Their blurb: “Neuroscience of Consciousness is an open access journal which publishes papers on the biological basis of consciousness, with an emphasis on empirical neuroscience studies in healthy populations and clinical settings. The journal also publishes empirically and neuroscientifically relevant psychological, methodological, theoretical, and philosophical papers. As well as the primary phenomenon of consciousness itself, relevant topics include interactions between conscious and unconscious processes; selfhood; metacognition and higher-order consciousness; intention, volition, and agency; individual differences in consciousness; altered states of…

On the evolution of the mammalian brain

On the evolution of the mammalian brain

Torday and Miller, Frontiers in Systems Neuroscience, 19 April 2016. The abstract: “Hobson and Friston have hypothesized that the brain must actively dissipate heat in order to process information (Hobson et al., 2014). This physiologic trait is functionally homologous with the first instantation of life formed by lipids suspended in water forming micelles- allowing the reduction in entropy (heat dissipation). This circumvents the Second Law of Thermodynamics permitting the transfer of information between living entities, enabling them to perpetually glean…

Damasio on consciousness

Damasio on consciousness

From the introduction to Chapter 9 of his new book The Strange Order of Things. “The term ‘consciousness’ applies to the very natural but distinctive kind of mental state described by the above [subjective] traits. The mental state allows its owner to be the private experiencer of the world around and, just as important, to experience aspects of his or her own being. For practical purposes, the universe of knowledge, current and past, that can be conjured up in a…

From computers to cultivation

From computers to cultivation

Another article Sulikowski referenced, highlighting the debate between the computational and 4E models. Therein it notes that the computational approach is akin to Chomsky’s computational linguistics. Note that Lakoff broke from Chomsky on this and went on to formulate embodied linguistics. It appears this debate is an ongoing battle in different fields. The abstract: “Does evolutionary theorizing have a role in psychology? This is a more contentious issue than one might imagine, given that, as evolved creatures, the answer must surely…

Extended evolutionary psychology

Extended evolutionary psychology

Article by Stotz (referenced in the last post), Frontiers in Psychology, 20 August 2014. This one is a bit more like Thompson’s approach. The abstract: “What kind mechanisms one deems central for the evolutionary process deeply influences one’s understanding of the nature of organisms, including cognition. Reversely, adopting a certain approach to the nature of life and cognition and the relationship between them or between the organism and its environment should affect one’s view of evolutionary theory. This paper explores…
