Weekly Neuroscience Update

Whole brain analyses revealed that higher dispositional mindfulness during painful heat was associated with greater deactivation of a brain region called the posterior cingulate cortex, a central neural node of the default mode network. Further, in those that reported higher pain, there was greater activation of this critically important brain region. image is credited to Zeidan et al.

Ever wonder why some people seem to feel less pain than others? A  new study may have found one of the answers – mindfulness.

Researchers at the Kavli Institute for Systems Neuroscience in Norway in have discovered a network of brain cells that express our sense of time within experiences and memories.

A new study reveals elevated glial activation in the brains of those with fibromyalgia.

Brains of baby boys born prematurely are affected differently and more severely than premature infant girls’ brains. This is according to a study published in the Springer Nature-branded journal Pediatric Research.

According to researchers, the speed at which a person speaks influences the way we hear and understand upcoming words. 

A new study reports under conditions of stress, KCNB1 builds up in the brain, before becoming toxic and promoting the production of amyloid beta. In Alzheimer’s patients, the KCNB1 levels are higher than in those without the condition.

Researchers report pyramidal neurons in the basolateral amygdala help us to recognize and categorize foods.

A new study sheds additional light on how the brain consolidates memory during sleep. Researchers report rapid fluctuations in gamma band activity in the hippocampus during nREM sleep helps facilitate memory reactivation.

Finally this week, researchers report on how the brain learns to recognize an individual face, regardless of where it appears in different visual locations.

How does cigarette addiction affect the brain?

The effects of nicotine upon brain regions involved in addiction mirror those of cocaine, according to new neuroscience research.

Aspirin and other anti-inflammatory drugs taken for pain relief may reduce the effectiveness of anti-depressants such as Prozac, say US researchers.

Moments of absent mindedness such as losing your keys could be the result of tiny parts of the brain taking “naps” to recharge, a study finds.Researchers discovered that contrary to popular opinion the brain is not always entirely asleep or awake but parts of it can go “offline”.

Neuroscientists at the California Institute of Technology and their colleagues have tied the human aversion to losing money to a specific structure in the brain-the amygdala.

Music is not only able to affect your mood — listening to particularly happy or sad music can even change the way we perceive the world, according to researchers from the University of Groningen.

The positive effects of mindfulness meditation on pain and working memory may result from an improved ability to regulate a crucial brain wave called the alpha rhythm. This rhythm is thought to “turn down the volume” on distracting information, which suggests that a key value of meditation may be helping the brain deal with an often-overstimulating world. And in other  mindfulness research – fMRI shows how mindfulness meditation changes the decision making process

Research shows that our brains understand music not only as emotional diversion, but also as a form of motion and activity.

Research shows that our brains understand music not only as emotional diversion, but also as a form of motion and activity. The same areas of the brain that activate when we swing a golf club or sign our name also engage when we hear expressive moments in music. Brain regions associated with empathy are activated, too, even for listeners who are not musicians.

And still on the theme of music and the brain, a recent study of seventy healthy adults ages sixty to eighty-three with various levels of music education starting around the age of ten showed impressive differences in brain functioning far later in life than any other research has previously shown.

A new study has suggested that sustained training in mindfulness meditation may impact distinct domains of human decision-making, enabling them to make decisions rationally.

Older bilingual adults compensate for age-related declines in brainpower by developing new strategies to process language, according to a recent study published in the journal Aging, Neuropsychology, and Cognition.

Emerging research suggest antidepressant medications may aid creation and survival of new brain cells after a brain injury.

New study examines brain processes behind facial recognition 

Finally, here is an interesting post from Chris Mooney on the science of why we don’t believe science.
