Pain and other feelings in human and animals

Pain and other feelings in human and animals

In this article the Damasios challenge Key that fish cannot feel pain because, counter to Key’s claim, pain is not the exclusive domain of the brain in humans or animals. The abstract: “Evidence from neuroanatomy, neurophysiology, and neuropsychology suggests that the experience of feelings in humans does not depend exclusively on structures of the cerebral cortex. It does not seem warranted to deny the possibility of feeling in animals on the grounds that their cerebral cortices are not comparable to…

Developmental cognitive neuroscience

Developmental cognitive neuroscience

Official journal of Flux: The Flux Society for Developmental Cognitive Neuroscience Editor-in-Chief:Professor Beatriz Luna, Ph.D   The journal publishes theoretical and research papers on cognitive brain development, from infancy through childhood and adolescence and into adulthood. It covers neurocognitive development and neurocognitive processing in both typical and atypical development, including social and affective aspects. Appropriate methodologies for the journal include, but are not limited to, functional neuroimaging (fMRI and MEG), electrophysiology (EEG and ERP), NIRS and transcranial magnetic stimulation, as…

General and specific-domain contributions to creativity

General and specific-domain contributions to creativity

From this article in Europe’s Journal of Psychology (2016). “The general objective of this study was to reexamine two views of creativity, one positing that there is a general creative capacity or talent and the other that creativity is domain-specific.  […] Multiple regressions uncovered particular relationships consistent with the view that creativity has both general and domain-specific contributions. Limitations, such as the focus on one domain, and future directions are discussed.” Also see comments.

The Neural Basis of Human prosocial behavior

The Neural Basis of Human prosocial behavior

A new Frontiers in Science ebook here. The blurb: With the rise of laboratory and field experimental economics, the famous prisoner’s dilemma, public good, dictator, ultimatum, and trust games have become the classical paradigms of studying prosocial behavior. Due to the increasing use of functional magnetic resonance imaging (fMRI), transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) with human subjects playing economic games, the neural basis of prosocial behavior has been uncovered by a large amount of neural…

More on Haidt

More on Haidt

Continuing this previous post: I’m looking at the section “conclusion and critique” of Haidt starting on p. 31. Gibbs appreciates that we should account for our earlier human history and more primitive brain centers in describing morality. But to limit it to these structures and history at the expense of later brain structures and evolutionary development is another thing. “The negative skew in Haidt’s descriptive work discourages study in moral psychology of higher reaches of morality such as rational moral…

The neuroscience of creativity

The neuroscience of creativity

Since this came up in our book discussion or Range yesterday,  something relevant from this article. It’s interesting how the salience network mediates between and integrates two normally one on, one off networks.  And how it is the connections between networks that seems to do the trick akin to the book’s description of how those with range make analogous connections between ideas and domains. “Three of these distinct brain networks — the default mode, the executive control network and the…

Elephant neural variation suggests a contemplative mind

Elephant neural variation suggests a contemplative mind

An article in The Conversation explores the variety of neuron structures in the elephant brain. Taken together, these morphological characteristics suggest that neurons in the elephant cortex may synthesize a wider variety of input than the cortical neurons in other mammals. In terms of cognition, my colleagues and I believe that the integrative cortical circuitry in the elephant supports the idea that they are essentially contemplative animals. Primate brains, by comparison, seem specialized for rapid decision-making and quick reactions to…

The Singularity is Near: When Humans Transcend Biology

The Singularity is Near: When Humans Transcend Biology

Kurzweil builds and supports a persuasive vision of the emergence of a human-level engineered intelligence in the early-to-mid twenty-first century. In his own words, With the reverse engineering of the human brain we will be able to apply the parallel, self-organizing, chaotic algorithms of  human intelligence to enormously powerful computational substrates. This intelligence will then be in a position to improve its own design, both hardware and software,  in a rapidly accelerating iterative process. In Kurzweil’s view, we must and…

Next discussion meeting Apr 2: Brain-Computer Interface, now and future

Next discussion meeting Apr 2: Brain-Computer Interface, now and future

During our next discussion meeting, we’ll explore the status, future potential, and human implications of neuroprostheses–particularly brain-computer interfaces. If you are local to Albuquerque, check our Meetup announcement to join or RSVP. The announcement text follows. Focal questions What are neuroprostheses? How are they used now and what may the future hold for technology-enhanced sensation, motor control, communications, cognition, and other human processes? Resources (please review before the meeting) Primary resources • New Brain-Computer Interface Technology (video, 18 m) https://www.youtube.com/watch?v=CgFzmE2fGXA • Imagining…
