Models and metaphors we live by
by Artem Kaznatcheev in Evolutionary Games Group
George Lakoff and Mark Johnson’s Metaphors we live by is a classic, that has had a huge influence on parts of linguistics and cognitive science, and some influence — although less so, in my opinion — on philosophy. It is structured around the thought that “[m]etaphor is one of our most important tools for trying […]... Read more »

Anthropomorphic Neuroscience Driven by Researchers with Large TPJs
by The Neurocritic in The Neurocritic
For immediate release — SEPTEMBER 26, 2014Research from the UCL lab of Professor Geraint Rees has proven that the recent craze for suggesting that rats have “regrets” or show “disappointment” is solely due to the size of the left temporal-parietal junction (TPJ) in the human authors of those papers (Cullen et al., 2014). This startling breakthrough was part of a larger effort to associate every known personality trait, political attitude, and individual difference with the size of a un........ Read more »

Genetics of Social Skills: Oxytocin Receptor Gene
by William Yates, M.D. in Brain Posts
Social neuroscience is an emerging emphasis in the field of neuroscience research.Social cognition is the subset of cognitive functions related to social processes and includes factors such as facial recognition, social memory and ability to form friendships and other social bonds.Impairment in social cognition is a known feature in autism, schizophrenia and other mental disorders. This type of impairment can produce significant problems in life adjustment, employment and human attachment.Geneti........ Read more »

Cannabis-induced Paranoia: Cognitive Mechanisms
by William Yates, M.D. in Brain Posts
Some individuals appear vulnerable to paranoia induced by exposure to tetrahydrocannabinol (THC) in cannabis.The mechanism for this effect is poorly understood.Daniel Freeman from University of Oxford along with colleagues in England and Switzerland recently conducted an interventional research study on this issue.In this study, 121 subjects were recruited to receive injections of THC in a laboratory setting.These subjects were required to have taken cannabis at least once before participation i........

Coping with Stress – Some Essential Constructs
by Vivek Misra in Uberbrain Research Frontier
Anxiety, insomnia, muscle tension, fatigue, high blood pressure, and anger are just some of the symptoms of stress. Stress not only affects our body, but also our behavior that can lead to social withdrawal. This presentation will explore the nature of our mind and the various factors in our lives that cause us stress. We will learn simple meditation techniques that can nourish the mind which will lead to increased focus, greater productivity, and improved relationships. ~ Pandi Gadadhara Pandi,........ Read more »

Supernatural believers see minds at work behind random patterns
“Theory of Mind” is the term used to describe the mental ability to put yourself inside the mind of someone else – to imagine what it is that they are thinking. Recently, there’s been some evidence that people who do not have a strong theory of mind are more likely to be atheists. For example, [Read More...]

Yet another study that attempts to make a link between vaccines and autism has been withdrawn by the publishers. Data from the CDC was re-analysed, and low and behold, a link between vaccine timing and autism was drawn, but only for African-American boys.

The neuroscience of self-control
by neurosci in Neuroscientifically Challenged
In the 1960s, a psychologist at Stanford named Walter Mischel began a series of experiments exploring the dynamics of self-control in children. In one such experiment, Mischel gave preschoolers the choice between two outcomes, one of which was clearly preferable. For example, they were able to choose between 2 marshmallows and 1 marshmallow (the experiments became known as the Stanford marshmallow experiments for this reason).But there was a catch. The experimenter would tell the children that h........ Read more »

Whitman Was Not a Neuroscientist
by The Neurocritic in The Neurocritic
Do I contradict myself?Very well then I contradict myself,(I am large, I contain multitudes.)-Walt Whitman, "Song of Myself" (from Leaves of Grass)Science is the search for objective truth based on physical laws of the universe. Scientific theories try to explain the consistent and predictable behavior of natural systems. They are generally reductionist, meaning that complex systems are reduced to simpler and more fundamental elements. The principles of physics, for instance, are expressed in th........ Read more »

Neurobiological Basis of Music Therapy
by Vivek Misra in Uberbrain Research Frontier
The basic and one of oldest socio-cognitive domains of Human species is music. Listening to music regularly helps to keep the neurons and synapses more active. Depending on the way sound waves are heard or pronounced, they have an impact in the way neurological (brain and nerve) system work in the human body. Neurological studies have identified that music is a valuable tool for evaluating the brain system [1]. Its observed that while listening to music, different parts of the brain are involved........

FDA Approves Novel Insomnia Drug Suvorexant (Belsomra)
by William Yates, M.D. in Brain Posts
Regular readers of this blog had a heads up last year on the development of orexin receptor antagonists for the treatment of insomnia.I posted a review of an Italian clinical drug trial in humans with insomnia paired with polysomnography. This study used three different doses of a orexin receptor antagonist (10 mg 30 mg and 60 mg).In a second post, I reviewed a sleep lab study of the effects of an orexin antagonist drug compared to zolpidem (Ambien) on sleep architecture.This second study found ........

Lithium For Aging Brain
by Vivek Misra in Uberbrain Research Frontier
Recent studies investigating Lithium, a drug commonly used for the treatment of mood disorders in humans, found its robust neurotrophic and neuroprotective effects which can help us exploring new novel, exciting, and promising targets. The molecular mechanism underlying lithium’s mood stabilizing effect is not yet unraveled. Suggested hypotheses include inositol-depletion via inhibition of inositol- monophosphatase and neuroprotection, via inhibition of GSK-3. Chronic lithium treatment inc........ Read more »

Brain Striatum and Loss-Chasing in Gambling
by William Yates, M.D. in Brain Posts
Pathological gambling (PG) is a pattern of gambling characterized by loss of control and large gambling debts.The near-miss phenomenon in gambling is the gaming scenario where gamblers sense they were very close to winning.This near-miss phenomenon can be programmed into slot machines. For example, a gambler might be presented frequently with four cherries when five cherries would result in a huge payout.The response to the near-miss in PG is often a sense that a big win is just around the corne........

Treating Sleep Problems Following Traumatic Brain Injury
by William Yates, M.D. in Brain Posts
Sleep problems are common following traumatic brain injury (TBI).In a previous post, I reviewed a study of the risk factors for sleep disorders following TBI.The most severe TBI is a risk factor for hypersomnia. Anxiety and depression following TBI increase risk for insomnia complaints.Few large studies of treatment for sleep problems after TBI exist. However, a recent manuscript outlined the potential benefit of treatment of sleep disorders in a series of 12 subjects.Catherine Wiseman-Hake........ Read more »
