Trauma's epigenetic fingerprint observed in children of Holocaust survivors

by Dr. Jekyll in Lunatic Laboratories

The children of traumatized people have long been known to be at increased risk for posttraumatic stress disorder (PTSD), and mood and anxiety disorders. However, there are very few opportunities to examine biologic alterations in the context of a watershed trauma in exposed people and their adult children born after the event.

Music from Your Brain

by The Neurocritic in The Neurocritic

The journal Brain has a new review on the history of converting the electroencephalogram (EEG) into sound (Lutters & Koehler, 2016). The translation of data into sound, known as sonification, has been applied to brain waves since the 1930s. In addition to early scientific and medical applications, sonification of the EEG has been used in the field of experimental music.In 1965, physicist Edmond Dewan and composer Alvin Lucier collaborated on Music for the Solo Performer:Sitting on a cha........

Scientists show that a 'Superman' disguise could actually work

by Dr. Jekyll in Lunatic Laboratories

Ever think it's silly that people don't recognize Clark Kent is actually Superman? Well as it turns out, glasses are actually a fairly good way to disguise yourself. In fact, researchers have shown that small alterations to a person's appearance, such as wearing glasses, can significantly hinder positive facial identification.

Brain Scans Show Your Dog Loves You And Food

by CAPB in Companion Animal Psychology Blog

An fMRI study shows different dogs have different preferences for food and social interaction.A recent fMRI study investigates individual differences in dogs’ preferences for food and social interaction with their owner. The results have been widely – and erroneously – reported as showing that dogs prefer praise to food. In fact, the results paint a far more interesting picture of how brain activity predicts canine choice.I think most people feel subjectively that their dog loves them. The........ Read more »

Caffeine reverts memory deficits by normalizing stress responses in the brain

by Dr. Jekyll in Lunatic Laboratories

A new study describes the mechanism by which caffeine counteracts age-related cognitive deficits in animals. The international teams showed that the abnormal expression of a particular receptor - the adenosine A2A, target for caffeine - in the brain of rats induces an aging-like profile namely memory impairments linked to the loss of stress controlling mechanisms.

Dyslexia Improvement in Medication Trial

by William Yates, M.D. in Brain Posts

Dyslexia or developmental reading disorder is a common learning disorder affecting about 5% of the school age population.Treatment of dyslexia is difficult and typically is focused on special education classes and reading exercises.Medication treatment for dyslexia is nearly unheard of as no FDA-approved drug is available for the condition.However, a recent randomized clinical drug trial found evidence to support the potential use of atomoxetine for dyslexia.Atomoxetine is a drug approved for at........

Use it or lose it: Stopping exercise decreases brain blood flow

by Dr. Jekyll in Lunatic Laboratories

We all know that we can quickly lose cardiovascular endurance if we stop exercising for a few weeks, but what impact does the cessation of exercise have on our brains? New research examined cerebral blood flow in healthy, physically fit older adults (ages 50-80 years) before and after a 10-day period during which they stopped all exercise.

Healing Prayer and the Brain: Not a Match Made in Heaven

by The Neurocritic in The Neurocritic

Activity of the medial prefrontal cortex after psycho-spiritual healing (Baldwin et al., 2016).Everything we do and feel and experience changes the brain. Psychotherapy, juggling, taxi driving, poverty, reading, drugs, art, music, anger, love. If it didn't we'd be dead. Why should prayer be any different? The trick is to accurately determine the structural or physiological changes that are unique to a specific activity. And when assessing the effectiveness of clinical interventions, how the chan........ Read more »

A visual nudge can disrupt recall of what things look like

by Dr. Jekyll in Lunatic Laboratories

Interfering with your vision makes it harder to describe what you know about the appearance of even common objects, according to researchers. This connection between visual knowledge and visual perception challenges widely held theories that visual information about the world -- that alligators are green and have long tails, for example -- is stored abstractly, as a list of facts, divorced from the visual experience of seeing an alligator....

Next steps in understanding brain function

by Dr. Jekyll in Lunatic Laboratories

The most complex piece of matter in the known universe is the brain. Neuroscientists have recently taken on the challenge to understand brain function from its intricate anatomy and structure. There is no sure way to go about it, and researchers in Madrid proposed a solution to the problem.

From :-D to =8-0 - Effects of Emoticons on the Brain

by Neuroskeptic in Neuroskeptic_Discover

An unusual study reports the effects of emoticons on human brain activity: Neural correlates of text-based emoticons



South Korean neuroscientists Ko Woon Kim et al. used fMRI to record brain activation in 18 volunteers who were shown various expressive text symbols, in both the Asian 'vertical' and Western 'horizontal' styles:

However, it turned out that the brain doesn't really respond to emoticons at all: there was no significant difference in the brain response to the real emoticons... Read more »

Making Music From Brainwaves: A History

by Neuroskeptic in Neuroskeptic_Discover

A new paper in Brain tells the story of attempts to turn brain waves into music. The authors are Bart Lutters and Peter J. Koehler: Brainwaves in concert: the 20th century sonification of the electroencephalogram


Electroencephalography (EEG), a technique for measuring brain electrical activity, was invented by German psychiatrist Hans Berger in 1929. Berger's EEG displayed the recorded activity in the form of graphs, using a mobile pen and a rotating drum of graph paper, but within 5 years,... Read more »

Too much activity in certain areas of the brain is bad for memory and attention

by Dr. Jekyll in Lunatic Laboratories

Neurons in the brain interact by sending each other chemical messages, so-called neurotransmitters. Gamma-aminobutyric acid (GABA) is the most common inhibitory neurotransmitter, which is important to restrain neural activity, preventing neurons from getting too trigger-happy and from firing too much or responding to irrelevant stimuli.

What To Do About Software Errors in fMRI?

by Neuroskeptic in Neuroskeptic_Discover

Last month we learned that a problem in commonly used fMRI analysis tools was giving rise to elevated rates of false positives. Now, another issue has been discovered in an fMRI tool. The affected software is called GingerALE and the 'implementation errors' are revealed in a new paper by Simon B. Eickhoff et al., the developers of the package.





GingerALE is a meta-analysis tool, that offers the ability to combine the results of multiple fMRI studies to assess the overall level of evide... Read more »

What are we getting wrong in neuroscience?

by neurosci in Neuroscientifically Challenged

In 1935, an ambitious neurology professor named Egas Moniz sat in the audience at a symposium on the frontal lobes, enthralled by neuroscientist Carlyle F. Jacobsen's description of some experiments Jacobsen had conducted with fellow investigator John Fulton. Jacobsen and Fulton had damaged the frontal lobes of a chimpanzee named "Becky," and afterwards they had observed a considerable behavioral transformation. Becky had previously been stubborn, erratic, and difficult to train, but post-operat........ Read more »

The Brain That Goes Through Phases: Temporal Metastates in fMRI

by Neuroskeptic in Neuroskeptic_Discover

Do you ever feel like your brain is stuck in a rut? A new study from neuroscientists James M. Shine and colleagues reveals the existence of 'temporal metastates' in human brain activity. These metastates are modes or patterns of activity that can persist over days, weeks or even months at a time, and they seem to be related to fluctuations in energy levels and attention.

The authors made use of a unique fMRI dataset, namely the results of repeated scanning of neuroscientist Russ Poldrack's br... Read more »
