Functional neuroanatomy of emotions: A meta-analysis - Springer

Functional neuroanatomy of emotions: A meta-analysis - Springer | Social Neuroscience Advances | Scoop.it

The application of functional neuroimaging to the study of human emotion has yielded valuable data; however, the conclusions that may be drawn from any one study are limited. We applied novel statistical techniques to the meta-analysis of 106 PET and fMRI studies of human emotion and tested predictions made by key neuroscientific models. The results demonstrated partial support for asymmetry accounts. Greater left-sided activity was observed for approach emotions, whereas neural activity associated with negative/withdrawal emotions was symmetrical. Support was also found for affect program emotion accounts. The activation distributions associated with fear, disgust, and anger differed significantly. These emotions were most consistently associated in activity in regions associated with selective processing deficits when damaged: the amygdala, the insula and globus pallidus, and the lateral orbitofrontal cortex, respectively. In contrast, the distributions for happiness and sadness did not differ. These findings are considered in the context of conceptualizations of the neural correlates of human emotion.

Video: Do Violent Video Games Destroy Human Empathy? | Social Neuroscience Advances | Scoop.it

Overexposure to violent video games decreases empathy towards others and blurs one’s sense of what is right and wrong, according to a recent study at Brock University.


The results of the study showed that this was not the case for casual gamers, but that it mainly held up for teenagers who play violent video games for an excessive amount of hours per day. Lissette Padilla and Elliot Hill discuss how moderation can prevent these negative effects, in this clip from the Lip News.

'Decoder' could lead to treatment for paralysis - Futurity

'Decoder' could lead to treatment for paralysis - Futurity | Social Neuroscience Advances | Scoop.it
Scientists tested a prosthesis that allows one animal to use its recorded neural activity to control limb movements in a different, sedated animal.

 

"The next step is to advance the development of brain-machine interface algorithms using the principles of control theory and statistical signal processing," says Maryam Shanechi. "Such brain-machine interface architectures could enable patients to generate complex movements using robotic arms or paralyzed limbs." (Credit: Maya Ibuki/Flickr) 

To help people suffering paralysis from injury, stroke, or disease, scientists have invented brain-machine interfaces that record electrical signals of neurons in the brain and translate them to movement. Usually, that means the neural signals direct a device, like a robotic arm.

 

Maryam Shanechi, assistant professor of electrical and computer engineering at Cornell University, hopes to help paralyzed people move their own limb, just by thinking about it.

 

When paralyzed patients imagine or plan a movement, neurons in the brain’s motor cortical areas still activate even though the communication link between the brain and muscles is broken. By implanting sensors in these brain areas, neural activity can be recorded and translated to the patient’s desired movement using a mathematical transform called the decoder.

 

These interfaces allow patients to generate movements directly with their thoughts.

Embedding Reward Signals into Perception and Cognition | Frontiers in Neuroscience

Despite considerable interest in the neural basis of valuation, how valuation affects cognitive processing has received relatively less attention. Here, we review evidence from recent behavioral and neuroimaging studies supporting the notion that motivation can enhance perceptual and executive control processes to achieve more efficient goal-directed behavior. Specifically, in the context of cognitive tasks offering monetary gains, improved behavioral performance has been repeatedly observed in conjunction with elevated neural activations in task-relevant perceptual, cognitive, and reward-related regions. We address the neural basis of motivation-cognition interactions by suggesting various modes of communication between relevant neural networks: (1) global hub regions may integrate information from multiple inputs providing a communicative link between specialized networks, (2) point-to-point interactions allow for more specific cross-network communication, and (3) diffuse neuromodulatory systems can relay motivational signals to cortex and enhance signal processing. Together, these modes of communication allow information regarding motivational significance to reach relevant brain regions and shape behavior.
