A study of brain function in cosmonauts reveals how the brain’s organization changes after an extended period in space, demonstrating the adaption required to live in a weightless environment.

Researchers are turning to artificial intelligence to find novel drugs that can block kappa opioid receptors with the hope to alleviate opioid addiction. The kappa opioid receptor is a protein in the brain that plays a role in pain management and addiction. When opioids bind to this receptor, it can produce a range of effects, including pain relief, as well as addiction and dependence.

Adults with high levels of attention-deficit hyperactivity disorder (ADHD) symptoms are more likely to experience anxiety and depression than adults with high levels of autistic traits, according to new research.

Scientists studying sleep difficulties have now published data in Frontiers in Neuroscience that shows that, even in an urban population experiencing disrupted sleep, humans experience longer REM sleep in winter than in summer and less deep sleep in autumn.

Regardless of the game type or length of time a child plays a video game, there is no correlation with a decline in cognitive ability, a new study reports.

Researchers have identified the in-vivo dynamics of synapses that underlie fear memory formation and extinction in the living brain. Fear memory formation and extinction are complex processes that involve changes in the connections between neurons, or synapses, in the brain. Understanding these processes at the level of individual synapses can provide important insights into the neural mechanisms of fear and anxiety disorders.

New research has found that children with conduct disorders exposed to maltreatment showed far more extensive changes in brain structure compared to children with conduct disorders who were not mistreated.

While kleptomania meets the criteria of addiction and is classified as a “Disruptive, Impulse-Control, and Conduct Disorder” by the American Psychiatry Society, few studies of the condition have been published to date. Now a team of researchers has recently found that patients with kleptomania exhibit distinct patterns of gazing and brain activity when shown images with environmental cues relevant to their symptoms. Such characteristics were not observed in healthy subjects.

Finally this week, researchers who examined the relationship between making music and mental health have found that musically active people have, on average, a slightly higher genetic risk for depression and bipolar disorder.

This Is Your Brain on Pokémon

Adults who played Pokémon video games extensively as children have a brain region that responds preferentially to images of Pikachu and other characters from the series.

The findings, published in the journal Nature Human Behavior, help shed light on mysteries about our visual system.

The first Pokémon game was released in 1996 and played by children as young as 5 years old, many of whom continued to play later versions of the game well into their teens and even early adulthood.

The games not only exposed these children to the same characters over and over again, it rewarded them when they won a Pokémon battle or added a new character to the in-game encyclopedia called the Pokédex.

Furthermore, every child played the games on the same handheld device – the Nintendo Game Boy – which had the same small square screen and required them to hold the devices at roughly the same arm’s length. Playing Pokémon on a tiny screen means that the Pokémon characters only take up a very small part of the player’s center of view. The eccentricity bias theory thus predicts that preferential brain activations for Pokémon should be found in the part of the visual cortex that processes objects in our central, or foveal, vision.

The new findings are just the latest evidence that our brains are capable of changing in response to experiential learning from a very early age, but that there are underlying constraints hardwired into the brain that shape and guide how those changes unfold.

Is The Internet Changing Your Brain? #SaferInternetDay

Leave a comment

Today, on #SaferInternetDay, I thought it a good time to return to a topic I’ve spoken about over the years. The question of whether our brains are being altered due to our increasing reliance on search engines, social networking sites, and other digital technologies, is always a timely one.

The Internet can be a force for positive change (as with new ‘cybertherapies’ to help patients with addiction and post-traumatic stress disorders), but equally, it can have a negative effect on mental health – especially with young people.

Today, I’m giving a talk to parents on the pros and cons of gaming and why gaming is so attractive to young people. I want to offer parents an opportunity to create a balance in their child’s world through understanding what is going on inside their child’s brain.

The talk takes place at Nenagh Arts Centre, Co Tipperary.  If you can’t attend in person, I’ll be sharing my slides later this week on SlideShare so check back in again.

This event is FREE but it is essential to book a seat with the Arts Centre on 067 34400 or through Eventbrite.

A game to map the brain #TEDxNijmegen 2013

Yesterday I shared a video from Moritz Helmstaedter a neuroscientist who has pioneered crowd sourcing for connectomics, engaging more than a hundred students to work together to analyze the immense amounts of data.  In today’s video recorded at #TEDxNijmegen, Amy Robinson, a research affiliate in MIT’s Department of Brain and Cognitive Sciences  explains that it takes a neuroscientist around 50 hours to map one cell, one neuron. And there are more than 80 billion neurons in one human brain. To complete the map of our brain MIT  are looking for help to accelerate this process by contributing to the EyeWire project. Watch the video which demonstrates how you can play the game.

The brain is a very complicated thing. You can however help us to fasten up the process of understanding as a non-scientist by joining EyeWire.” EyeWire is a game to map neural networks. Anyone can play, and you don’t need a scientific background ~ Amy Robinson

The researchers report that the findings may help lead to the development of effective and fast-acting drugs to treat depression, particularly in psychiatric emergencies.

UC Berkeley neuroscientists have found that the slow brain waves generated during the deep, restorative sleep we typically experience in youth play a key role in transporting memories from the hippocampus – which provides short-term storage for memories – to the prefrontal cortex’s longer term “hard drive.”

Researchers have found altered connectivity in the brain network for body perception in people with anorexia: The weaker the connection, the greater the misjudgement of body shape.

A group of scientists planning to map all the major connections in the human brain began studying their first test subjects in August. The $30 million Human Connectome Project will trace the main neural pathways that link the roughly 500 major regions in the brain, illuminating how biological circuitry underlies our mental functions. MRI scans of 1,200 people, including 300 pairs of twins, will be used to compile an atlas of communication routes throughout the brain. The resulting blueprint will also reveal how brain connectivity varies from person to person.

What is the secret to a great game?

TEDxMaastricht starts today with the theme ‘The Future of Health’ and browsing through this list of abstracts of  health game nominees for the Future of Health award (the winner to be announced today), I was particularly struck by the concept of Daydream by Jan Jonk. 

I am very interested in and have lectured on the gaming brain. The key properties of a successful game are that it must (i) impart independence to the player – allow their own style to shine through, (ii) be interesting and complex and (iii) have a relationship between effort and reward.

Games and brains 

In the game Daydream players with locked-in syndrome or other similar paralysing brain dysfunctions such as stroke, wear a plug-and-play neuroheadset that measures their mental states to alter a rich visual world in which the world’s ecosystem can be influenced by changing the climate through their brainwaves – for instance – by concentrating, relaxing and thinking creatively.

Shining a light in dark corners 

By reaching those brain areas which would be otherwise inaccessible, Daydream has the potential to emotionally empower these patients by drawing them out of their social confinement and giving them a manner of social independency and act as a powerful antidote to depression. In addition, the game may allow doctors, psychologists, family members and pets to enter the patient’s world as avatars – as seen in James Cameron’s movie Avatar – where the wheelchair bound Sully whose avatar becomes a warrior leader in an alternative world.  

All patients are different 

As with inter-individual preferences in the general population the game may need to be tweaked to motivate each patient to engage.  Balancing the world’s ecosystem by influencing the climate may work for some patients while building a motorbike from scratch or designing and maintaining a garden may be of more interest to others.
