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
“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…
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…
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…
And implies an event horizon of the human brain. There’s a mouthful, a new title in NeuroQuantology (15:3, September 2017). The abstract follows, also a brainful. This will take some reading and digesting, provided I have the requisite capacity to understand it (which remains to be seen). “Our brain is not a ‘stand alone’ information processing organ: it acts as a central part of our integral nervous system with recurrent information exchange with the entire organism and the cosmos. In this study, the brain…
Abstract In recent years, the bidirectional communication between the gut microbiome and the brain has emerged as a factor that influences immunity, metabolism, neurodevelopment and behaviour. Cross-talk between the gut and brain begins early in life immediately following the transition from a sterile in utero environment to one that is exposed to a changing and complex microbial milieu over a lifetime. Once established, communication between the gut and brain integrates information from the autonomic and enteric nervous systems, neuroendocrine and neuroimmune signals,…
