Go ahead, try tickling yourself on your inner forearm or neck. If you're like most people, you'll find it doesn't work. The sensation would make you shiver or giggle with ticklishness if someone else did it, but when you do it yourself, it no longer has any tickle power.The inability of most people to tickle themselves has been documented by psychologists for a while, and it's thought be due to the fact that the brain creates predictions of the sensory consequences of our own actions, and ........

Very possibly, is the answer to the question that titles this post on how the diagnostic borders between mitochondrial disease and chronic fatigue syndrome (CFS) might be blurred. I bring to your attention the case report published by Fernando Galán and colleagues  (open-access available here) as an example.Detailing the experiences of a 30-year old male who "appeared to meet the CDC-1994/Fukuda criteria for CFS [chronic fatigue syndrome]" and for whom 1 year of "cognitive behavioral th........

Why humans and other animals sleep is one of the remaining deep mysteries of physiology. One prominent theory in neuroscience is that sleep is when the brain replays memories "offline" to better encode them ("memory consolidation"). A prominent and competing theory is that sleep is important for rebalancing activity in brain networks that have been perturbed during learning while awake.

In a word, yes. But perhaps not in the way you might think. Researchers were interested in seeing if the race of parties involved in battered spouse syndrome case defenses would make a difference in how jurors made decisions about verdicts. The researchers say their study is a contribution to the “scarce literature on the […]

According to UltraRunning Magazine, an ultra run is anything longer than a standard marathon of 26 miles, but it’s not unusual for people to participate in gruelling runs that take place in punishing environments over days or even weeks. For people who struggle to run to catch a bus, the idea of deliberately putting yourself through this kind of physical punishment, for fun, seems little short of crazy. Yet this is a sport that’s on the increase – the number of official events has doubled ........ Read more »

"People with autism 'die younger', warns charity" went the very stark BBC headline recently.Today I'd like to bring your attention to the recent report published by Autistica titled: 'Personal tragedies, public crisis' making the headlines, highlighting how people with autism face a considerably enhanced risk of early mortality compared with the general population  (see here for my take).Although making quite sober reading and rightly using some very emotive language, I think m........

A new study is the first to report that the relationship between nightmares and suicidal behaviors is partially mediated by a multi-step pathway via defeat, entrapment, and hopelessness. Results show that suicidal thoughts, plans or attempts were present in 62 percent of participants who experienced nightmares and only 20 percent of those without nightmares.

Traumatic brain injury (TBI), also known as intracranial injury, is a substantial head injury that results in damage to the brain. This damage can cause a wide spectrum of possible health outcomes. Factors that are likely to influence neuropsychiatric outcome in TBI can be classified as pre-injury, injury and post-injury factors. Injury-related factors include a) the type of physical injury

Our bodily sense of self contributes to our personal feelings of awareness as a conscious being. How we see our bodies and move through space and feel touched by loved ones are integral parts of our identity. What happens when this sense of self breaks down? One form of dissolution is Depersonalization Disorder (DPD).1 Individuals with DPD feel estranged or disconnected from themselves, as if their bodies belong to someone else, and “they” are merely a detached observer. Or the self feel........ Read more »

THE AMYGDALA SHOWN ALONG WITH OTHER LIMBIC SYSTEM STRUCTURES.
The amygdala---or, more appropriately, amygdalae, as there is one in each cerebral hemisphere---was not recognized as a distinct brain region until the 1800s, and it wasn't until the middle of the twentieth century that it began to be considered an especially significant area in mediating emotional responses. Specifics about the role of the amygdala in emotion remained somewhat unclear, however, ........ Read more »

They say that once you’ve learned to ride a bicycle, you never forget how to do it. Unfortunately for students who hope this applies to studying, they might not like new research suggesting that while learning, the brain is actively trying to forget. While this may at first blush seem like a bad thing, it actually may be useful for those suffering from PTSD.

Hong Kong and Japanese teachers appear to be more attentive to the processing demands of relational comparisons than are U.S teachers.

Participants were recruited via online asexuality communitiesSex, or talk of it, is everywhere, whether filling our TV screens or the conversations at the bar after work. Imagine then that you're one of the estimated one per cent of the population who actually don't have any sexual desire – an increasingly recognised status usually referred to as being "asexual".

Evidence is building up that, because religion helps people to deal with uncertainties of life, it’s particularly attractive to the kind of people who have a hard time dealing with uncertainty.
