Affective neuroscience of self-generated thought

Affective neuroscience of self-generated thought

By Fox et al. (2018), Annals of the New York Academy of Sciences, 12 May, pp. 1 – 27. The abstract: “Despite increasing scientific interest in self-generated thought—mental content largely independent of the immediate environment—there has yet to be any comprehensive synthesis of the subjective experience and neural correlates of affect in these forms of thinking. Here, we aim to develop an integrated affective neuroscience encompassing many forms of self-generated thought—normal and pathological, moderate and excessive, in waking and in…

LSD produces new type of harmonic order in the brain

LSD produces new type of harmonic order in the brain

See this study. The blurb: “New brain published in the journal Scientific Reports sheds new light on how LSD produces its psychedelic effects. The drug resulted in the ’emergence of new type of order in the brain,’ the researchers found. The study used a new mathematical method to analyze brain activity, known as connectome-harmonic decomposition, to examine how LSD caused alterations in consciousness. A connectome is a distinctive pattern of neural connections — like a wiring diagram of the brain.”

Neural responses to media a strong predictor of friendship

Neural responses to media a strong predictor of friendship

“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…

Altered states and altered traits

Altered states and altered traits

Good, brief clip on the difference between the above, and how meditation can turn altered states into lasting traits that one carries in their daily life. Aside from the physiological benefits, if we can just dump the metaphysical mumbo jumbo that accompanies traditional interpretations of what these states and traits mean then we’ll have made progress toward a postmetaphysical cultural metaphor.

Consciousness in the world is scale invariant

Consciousness in the world is scale invariant

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…

Dancing mitigates aging decline

Dancing mitigates aging decline

See the study here in Frontiers of Human Neuroscience, 15 June 2017. From the abstract: “Dancing seems a promising intervention for both improving balance and brain structure in the elderly. It combines aerobic fitness, sensorimotor skills and cognitive demands while at the same time the risk of injuries is low. […] Hence, dancing constitutes a promising candidate in counteracting the age-related decline in physical and mental abilities.”

The real problem of consciousness

The real problem of consciousness

See this article. A few excerpts: “A new picture is taking shape in which conscious experience is seen as deeply grounded in how brains and bodies work together to maintain physiological integrity – to stay alive.” “The brain is locked inside a bony skull. All it receives are ambiguous and noisy sensory signals that are only indirectly related to objects in the world. Perception must therefore be a process of inference, in which indeterminate sensory signals are combined with prior…

Real and false reason

Real and false reason

Some liberals (and scientists) still think that reason is somehow above and beyond emotion. When I suggest framing in emotional terms they say sure, but that works only for emotional issues as if reason is something beyond emotion. So here’s a reminder from  this Lakoff classic: “It is a basic principle of false reason that every human being has the same reason governed by logic — and that if you just tell people the truth, they will reason to the…
