TEDxRheinMain - Prof. Dr. Thomas Metzinger - The Ego Tunnel - YouTube - 1 views

  •  
    Brain, bodily awareness, and the emergence of a conscious self: these entities and their relations are explored by Germanphilosopher and cognitive scientist Metzinger. Extensively working with neuroscientists he has come to the conclusion that, in fact, there is no such thing as a "self" -- that a "self" is simply the content of a model created by our brain - part of a virtual reality we create for ourselves. But if the self is not "real," he asks, why and how did it evolve? How does the brain construct the self? In a series of fascinating virtual reality experiments, Metzinger and his colleagues have attempted to create so-called "out-of-body experiences" in the lab, in order to explore these questions. As a philosopher, he offers a discussion of many of the latest results in robotics, neuroscience, dream and meditation research, and argues that the brain is much more powerful than we have ever imagined. He shows us, for example, that we now have the first machines that have developed an inner image of their own body -- and actually use this model to create intelligent behavior. In addition, studies exploring the connections between phantom limbs and the brain have shown us that even people born without arms or legs sometimes experience a sensation that they do in fact have limbs that are not there. Experiments like the "rubber-hand illusion" demonstrate how we can experience a fake hand as part of our self and even feel a sensation of touch on the phantom hand form the basis and testing ground for the idea that what we have called the "self" in the past is just the content of a transparent self-model in our brains. Now, as new ways of manipulating the conscious mind-brain appear on the scene, it will soon become possible to alter our subjective reality in an unprecedented manner. The cultural consequences of this, Metzinger claims, may be immense: we will need a new approach to ethics, and we will be forced to think about ourselves in a fundamentally new way. At

Biological Link between Cancer and Depression - The Naked Scientists May 2009 - 0 views

  •  
    "Leah Pyter: Well basically what we know is that patients with cancer have a higher likelihood of also developing depression at some point in their disease progression, so whether that occurred before and is predisposing them to cancer, or it's due to the tumours themselves, or other aspects of having the disease, we don't know. We were only studying right now whether the cancer itself can cause depression. Chris Smith: How could a tumour trigger depression, because a tumour can occur anywhere in the body, therefore at the remote sites in the brain, so how could it trigger changes in brain activity? Leah Pyter: Sure, well what we hypothesized was that the tumours themselves can produce cytokines which has been shown before. Chris Smith: These are inflammatory chemicals that drive the immune system? Leah Pyter: Right, exactly! And there is also a pile of research on how cytokines can access the brain specifically regions of the brain that are associated with depression and anxiety and emotional behaviours, and they can access the brain both tumourally through the blood, or neurally through the vegas nerves.

How your memories can be twisted under social pressure | KurzweilAI - 1 views

  •  
    Listen up, Facebook and Twitter groupies: how easily can social pressure affect your memory? Very easily, researchers at the Weizmann Institute and University College London have proved, and they think they even know what part of the brain is responsible. The participants conformed to the group on these "planted" responses, giving incorrect answers nearly 70% of the time. Volunteers watched a documentary film in small groups. Three days later, they returned to the lab individually to take a memory test, answering questions about the film. They were also asked how confident they were in their answers. They were later invited back to the lab to retake the test. This time, the subjects were also given supposed answers of the others in their film-viewing group (along with social-media-style photos) while being scanned in a functional MRI (fMRI) that revealed their brain activity. Is most of what you know false? Planted among these were false answers to questions the volunteers had previously answered correctly and confidently. The participants conformed to the group on these "planted" responses, giving incorrect answers nearly 70% of the time. To determine if their memory of the film had actually undergone a change, the researchers invited the subjects back to the lab later to take the memory test once again, telling them that the answers they had previously been fed were not those of their fellow film watchers, but random computer generations. Some of the responses reverted back to the original, correct ones, but get this: despite finding out the scientists messed with their minds, close to half of their responses remained erroneous, implying that the subjects were relying on false memories implanted in the earlier session. An analysis of the fMRI data showed a strong co-activation and connectivity between two brain areas: the hippocampus and the amygdala. Social reinforcement could act on the amygdala to persuade our brains to replace a strong memory wi

How Dangerous Is Brain Cancer? - 0 views

  •  
    Tumors causing brain cancer are usually formed in human brains, and this kind is largely called primary tumors. But sometimes tumors formed in some other parts of the body are carried to the brain and are popularly known as metastatic tumors.

Brain Tumor and Brain Cancer - 0 views

  •  
    Brain tumor and brain cancer are synonymous terms. Due to the formation of abnormal cells in the human brain this disease occurs. Human beings below the age of 40 years, especially the kids are the most affected ones by this particular sort of cancer.

Mind-reading scan identifies simple thoughts - health - 26 May 2011 - New Scientist - 3 views

  •  
    A new new brain imaging system that can identify a subject's simple thoughts may lead to clearer diagnoses for Alzheimer's disease or schizophrenia - as well as possibly paving the way for reading people's minds. Michael Greicius at Stanford University in California and colleagues used functional magnetic resonance imaging (fMRI) to identify patterns of brain activity associated with different mental states. He asked 14 volunteers to do one of four tasks: sing songs silently to themselves; recall the events of the day; count backwards in threes; or simply relax. Participants were given a 10-minute period during which they had to do this. For the rest of that time they were free to think about whatever they liked. The participants' brains were scanned for the entire 10 minutes, and the patterns of connectivity associated with each task were teased out by computer algorithms that compared scans from several volunteers doing the same task. This differs from previous experiments, in which the subjects were required to perform mental activities at specific times and the scans were then compared with brain activity when they were at rest. Greicius reasons his method encourages "natural" brain activity more like that which occurs in normal thought.

Science Friday Archives: Meditation and the Brain - 1 views

  •  
    New research looks at the effects of studying a form of meditation on brain connectivity. Writing in the Proceedings of the National Academy of Science, researchers in China and the University of Oregon describe experiments on 45 students, some of whom were taught a meditation technique known as integrative body-mind training (IBMT). The researchers used brain imaging techniques to examine fibers connecting brain regions before and after training. Students trained in the IBMT approach for 11 hours or more appeared to develop new fibers in a part of the brain that helps a person regulate behavior. Control subjects did not form the new fibers. But what does the presence of those fibers actually mean -- and what is the meditation technique doing? We'll talk about it.

Brain is organized like the Internet: USC neuroscientists | KurzweilAI - 1 views

  •  
    A study by USC scientists of the brain connections in a small area of the rat brain showed them as patterns of circular loops, suggesting that at least in this part of the rat brain, the wiring diagram looks like a distributed network, rather than a hierarchy, the traditional view.

Natural brain state is primed to learn - life - 19 August 2011 - New Scientist - 0 views

  •  
    Apply the electrodes... Externally modulating the brain's activity can boost its performance. The easiest way to manipulate the brain is through transcranial direct current stimulation (tDCS), which involves applying electrodes directly to the head to influence neuron activity with an electric current. Roi Cohen Kadosh's team at the University of Oxford showed last year that targeting tDCS at the brain's right parietal lobe can boost a person's arithmetic ability - the effects were still apparent six months after the tDCS session (newscientist.com/article/dn19679). More recently, Richard Chi and Allan Snyder at the University of Sydney, Australia, demonstrated that tDCS can improve a person's insight. The pair applied tDCS to volunteers' anterior frontal lobes - regions known to play a role in how we perceive the world - and found the participants were three times as likely as normal to complete a problem-solving task (newscientist.com/article/dn20080). Brain stimulation can also boost a person's learning abilities, according to Agnes Flöel's team at the University of Münster in Germany. Twenty minutes of tDCS to a part of the brain called the left perisylvian area was enough to speed up and improve language learning in a group of 19 volunteers (Journal of Cognitive Neuroscience, DOI: 10.1162/jocn.2008.20098). Using the same technique to stimulate the brain's motor cortex, meanwhile, can enhance a person's ability to learn a movement-based skill (Proceedings of the National Academy of Sciences, DOI: 10.1073/pnas.0805413106).

John Cryan: Mind-Altering Bugs - ScienceNOW - 0 views

  •  
    "Hundreds of species of bacteria call the human gut their home. This gut "microbiome" influences our physiology and health in ways that scientists are only beginning to understand. Now, a new study suggests that gut bacteria can even mess with the mind, altering brain chemistry and changing mood and behavior. In recent years, researchers have become increasingly interested in how gut bacteria might influence the brain and behavior, says John Cryan, a neuroscientist at University College Cork in Ireland. So far, most of the work has focused on how pathogenic bugs influence the brain by releasing toxins or stimulating the immune system, Cryan says. One recent study suggested that even benign bacteria can alter the brain and behavior, but until now there has been very little work in this area, Cryan says."

Our brains are more like birds' than we thought - 0 views

  •  
    For more than a century, neuroscientists believed that the brains of humans and other mammals differed from the brains of other animals, such as birds (and so were presumably better). Researchers have now found that a comparable region in the brains of chickens concerned with analyzing auditory inputs is constructed similarly to that of mammals.
