Zoned-out rats may give clue to consciousness - life - 12 October 2011. 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. The default mode network (DMN) is one of about 10 networks of brain regions that are active when a person is at rest. What makes the DMN interesting is that it becomes active when a person is asked to let their mind wander, but the network's activity drops away completely as soon as that person is given an external task. Building on recent evidence that anaesthetised monkeys might have a similar network, Wim Vanduffel and his colleagues at the Catholic University of Leuven (KUL) in Belgium collected a host of data from 15 studies which imaged the brain activity of 10 awake monkeys. Why free will may be an illusion.
Time on the Brain: How You Are Always Living In the Past, and Other Quirks of Perception. 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. Card trick reveals the subconscious mind is on watch - life - 16 November 2011. The period of the brain pretending to be the mind. 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). Where is The Mind?: Science gets puzzled and almost admits a non-local mentalscape. 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. Anesthesia May Leave Patients Conscious—and Finally Show Consciousness in the Brain. Consciousness: Mind Over Matter. The Blog : The Mystery of Consciousness II. (Photo by h.koppdelaney) The universe is filled with physical phenomena that appear devoid of consciousness.
Test measures spark of consciousness. Consciousness: Mind Over Matter. How does anesthesia disturb self-perception? 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. Persons under regional anaesthetic describe these very same false images. Think time flies? Well actually, you may be right - Technology & science - Tech and gadgets - Gizmodo. Time flies when you're having fun.
But you're at work, and work sucks. So how is it 5 p.m. already? When we talk about "losing time," we aren't referring to that great night out, or that week of wonderful vacation, or the three-hour film that honestly didn't feel like more than an hour. No, when we fret about not having enough time, or wonder where exactly all those hours went, we're talking about mundane things. The workday. Why does that happen? First of all, yes In understanding any complex issue, especially a psychological one, intuition doesn't usually get us too far.
Consciousness of subjective time in the brain — PNAS. 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.
