HUMAN minds wander when they have nothing else to do. This is when people start to introspect, using a specific network of brain structures. The same network has now been identified in monkeys and rats, suggesting that "zoning out" might serve a key function in our survival. The findings raise questions over whether lower animals might also be capable of something akin to introspection.
MacGregor Campbell, consultant Does free will actually exist? Or are we all just biological robots?
I always knew we humans have a rather tenuous grip on the concept of time, but I never realized quite how tenuous it was until a couple of weeks ago, when I attended a conference on the nature of time organized by the Foundational Questions Institute. This meeting, even more than FQXi’s previous efforts, was a mashup of different disciplines: fundamental physics, philosophy, neuroscience, complexity theory. Crossing academic disciplines may be overrated, as physicist-blogger Sabine Hossenfelder has pointed out , but it sure is fun. Like Sabine , I spend my days thinking about planets, dark matter, black holes—they have become mundane to me. But brains—now there’s something exotic.
The mind is different from the brain , just as psychology is different from biology. Although mental processes are associated with some biochemical/neurological operations, some researchers and the popular media have misrepresented the association between the two systems as the causal relation (biochemical changes cause psychological experiences) or simply seen the two as the same. With the growing use of psychophysiological measures such as fMRI, PET, EEG, MEG, and optical neuroimaging, it has become pervasive to hear that biological events underlie (are more fundamental than) psychological events. For example, announcements such as "depression is a chemical imbalance" or " schizophrenia is a brain disease" became the mainstream during the past two decades. Neuroimaging has also been used to explain political or voting behaviors or attitudes, criminal behavior or other social interactions (e.g., Miller, 2010).
This will be the last "home-produced" blog entry for a while [save the short "Everyday Spirituality" which will follow it as a sign-off] . West Virginia beckons tomorrow morning and off I will go to whatever that entails. As I said in one of the commentary responses the other day, I hope that reading two journal runs "cover-to-cover" will bring up a few thoughts worth sharing.
Vaughan Bell is a clinical and research psychologist based at the Institute of Psychiatry, King’s College London and currently working in Colombia. He’s also working on a book about hallucinations due to be out in 2013.
(Photo by h.koppdelaney ) The universe is filled with physical phenomena that appear devoid of consciousness. From the birth of stars and planets, to the early stages of cell division in a human embryo, the structures and processes we find in Nature seem to lack an inner life. At some point in the development of certain complex organisms, however, consciousness emerges.
Jan. 24, 2011 — An Inserm research team in Toulouse, led by Dr Stein Silva (Inserm Unit 825 "Brain imaging and neurological handicaps"), working with the "Modelling tissue and nociceptive stress" Host Team (MATN IFR 150), were interested in studying the illusions described by many patients under regional anaesthetic. In their work, to be published in the journal Anesthesiology , the researchers demonstrated that anaesthetising an arm affects brain activity and rapidly impairs body perception. The ultimate aim of the work is to understand how neuronal circuits are reorganised at this exact moment in time and to take advantage of anaesthesia to reconfigure them correctly following trauma. This would allow anaesthetic techniques to be used in the future to treat pain described by amputated patients in what are known as "phantom limbs." Neuroscience research in recent years has shown that the brain is a dynamic structure.
Time flies when you're having fun.
Author Affiliations Contributed by Endel Tulving, November 9, 2010 (sent for review June 13, 2010) Abstract “Mental time travel” refers to conscious experience of remembering the personal past and imagining the personal future. Little is known about its neural correlates.
The goal of this topic is to concisely state the best theories of consciousness, and to quantitatively measure how much consensus there is for each. The focus of this topic is on the Explanatory Gap or the phenomenal nature of what consciousness is like. Is Phenomenal redness a quality of the strawberry we are looking at? Or in other words is it a property of the initial cause of the perception process, or is it a quality of the final result of the perception process - our knowledge of such? Or is it some combination or something else different entirely?
