A new study by Martin-Luther-University Halle-Wittenberg found that brain stimulation can influence decisions, making choices faster with anodal stimulation and slower with cathodal stimulation. The research used transcranial direct current stimulation to activate or inhibit specific brain regions.
Neuroscientists at Penn Medicine identified a brain mechanism that enables focus despite visual distractions. By analyzing neuron activity in animal models, they discovered 'beta bursts' in the lateral prefrontal cortex, which suppress distracting stimuli and direct attention towards tasks.
Researchers at HSE University used transcranial magnetic stimulation to suppress brain activity in the dorsolateral prefrontal cortex, leading to test subjects making less rational decisions. The study provides insight into the mechanisms behind gaming addiction and offers a potential new approach to understanding risky choice.
New research finds elevated activity in the right dorsolateral prefrontal cortex when anticipating stuttering, indicating a key role in cognitive control. This study provides fresh insight into how stutterers process anticipation, offering potential implications for therapy.
Researchers suppressed cortical excitability to resolve self-interest vs. prosocial motivations in favor of cooperation, particularly in dictator games. In generosity games, no effect was observed. The study suggests the dorsolateral prefrontal cortex plays a key role in resolving conflicts between self-interest and prosociality.
A new study by Duke University researchers found that people at-risk for anxiety were less likely to develop the disorder if they had higher activity in a region of the brain responsible for complex mental operations. Higher functioning dorsolateral prefrontal cortex may buffer against worsening anxiety.
Researchers pinpointed the brain's dorsolateral prefrontal cortex as responsible for credit assignment, a mechanism that enables learning from success. The study used non-human primates to demonstrate the cortex's role in linking causes and effects.
Researchers identified three key brain regions involved in hypnosis, including decreased activity in the dorsal anterior cingulate and increased connections between the dorsolateral prefrontal cortex and the insula. These changes may help understand how hypnosis affects perception and body control.
Researchers found hyperconnectivity between brain networks in adolescent boys with Internet gaming disorder, which may help them respond to new information but also increase distractibility and poor impulse control. The study provides insights into the neural basis of compulsive video game play.
Researchers found that disrupting brain activity in a specific area can change punishment decisions without affecting blame judgments. This study suggests that the dorsolateral prefrontal cortex integrates information from other parts of the brain to determine punishment and moral responsibility.
The study found that two specific brain regions, the posterior cingulate cortex and rostral anterior cingulate cortex, are activated when making defensive or offensive strategies. This suggests that intuition plays a key role in rapid strategic decisions, rather than deliberate reasoning.
A study published in Neuron found that precommitment, or restricting access to tempting options, is a more effective self-control strategy than willpower. This approach can help individuals avoid unhealthy choices and achieve their weight loss goals.
A new study found that training individuals on a working-memory task can improve their performance on various cognitive tasks, including problem-solving and attentional control. The training exercise increased connectivity between specific brain areas, particularly the parietal and frontal brain regions.
Researchers found that the brain's dorsolateral prefrontal cortex plays a key role in rational inference, but not emotions, in 'mindreading'. The study suggests that certain executive functions like cognitive flexibility may be important for processing what someone else is thinking.
Researchers at UC San Diego School of Medicine have reviewed the neurobiology of wisdom, identifying key brain regions involved in its attributes such as empathy, compassion and emotional stability. The study suggests an optimal balance between primitive and pre-frontal cortex brain regions may enhance wisdom.
Researchers found differences in activation strength between male and female groups on a verbal fluency task, with women scoring higher than men. The study suggests that sex differences may be related to both performance level and neurocognitive variations.
A recent Emory University study used fMRI to investigate how Democrats and Republicans process information during the 2004 US Presidential election. The researchers found that emotional circuits in the brain lit up when partisans held biased opinions, rather than rational reasoning.
Researchers at NIMH identified a brain region in the frontal cortex as the site of perceptual decision-making, which weighs competing signals from specialized visual processing areas. The discovery could explain why harder-to-identify images evoke slower responses in this area.
A study found that blind individuals using Braille reading strategies activate areas of the brain normally reserved for vision, suggesting a novel way of utilizing occipital cortex. This activation is similar to what is observed in sighted individuals when reading print or receiving tactile stimulation.
Researchers found that verbal storage tasks activate left-hemisphere speech areas, while spatial storage tasks activate specific areas of the right cortex. The study provides strong evidence for a more precise understanding of how various regions of the frontal cortex are involved in specific mental activities.
