Researchers at Johns Hopkins University have identified a region in the brainstem that controls attention by suppressing distractions and directing focus. This discovery could lead to more targeted treatments for attention disorders like ADHD.
The superior colliculus, an ancestral brain structure, enables the brain to distinguish objects from the background and detect relevant stimuli in space. It generates centre–surround interactions independently, allowing for the detection of contrasts, edges, and salient features.
A study published in PLOS Biology finds no evidence of subcortical processing for selective attention, suggesting the auditory cortex 'turns up the volume' on focused sound. Researchers used novel experimental techniques to test this hypothesis using audiobooks and diotic and dichotic listening tasks.
Research reveals that even short-term exposure to high levels of particulate matter air pollution impairs cognitive functions such as selective attention and emotion recognition. This study highlights the urgent need for stricter air quality regulations and public health measures to combat the harmful effects of pollution on brain health.
A study found that people's eyes are drawn to areas with high potential for change before any movement occurs, even when the scene appears static. This behavior is not limited to animate objects and has significant implications for intelligent machines.
A breakthrough study found that light exercise can improve cognitive health in adults with Down syndrome, leading to improved information processing and attention. After just eight weeks of walking, participants showed significant increases in physical fitness and reductions in errors during cognitive assessments.
A new study found that children's attention wandered to all parts of a screen while completing a task, but this helped them notice important things when the task unexpectedly changed. Adults, on the other hand, quickly focused their attention on one feature and missed important clues.
Researchers from the University of Birmingham propose new techniques to test for rhythmic oscillations in visual attention, suggesting that attention may not switch between threats and opportunities in a predictable rhythm. These new statistical tools aim to shed light on brain conditions like attention deficit disorder.
Scientists at MIT's Picower Institute mapped thousands of inputs to the anterior cingulate cortex and lateral posterior thalamus, finding that both regions receive input from non-sensory areas. The study provides a detailed roadmap for understanding selective attention in mice.
Research reveals that the brain's electrical rhythms fluctuate between high precision and low precision states several times per second, affecting how relevant information is transmitted. Cross-frequency coupling enables selective attention by modulating the strength of different frequencies, while distinguishing between different type...
Researchers used MEG to measure brain activity while participants listened to simultaneous math equations and sentences, finding separate networks for each. The parietal lobe processed math and the temporal lobe processed language, with activity tracking every word and symbol.
Researchers from the University of Malaga have developed a software to improve cognitive abilities in athletes, particularly soccer players. The study found that computerized training enhances their selective attention, enabling them to focus on specific stimuli and make creative decisions during games.
Researchers found that children can quickly adjust to changing circumstances and notice everything, while adults tend to selectively focus on important information. This difference in attention distribution may be an advantage for young children's learning abilities.
A recent study published by the Acoustical Society of America found that listening to meaningful sounds, such as music or conversation, can decrease performance on cognitive tasks. In contrast, meaningless noises have a less significant impact on cognitive performance and subjective annoyance.
A small study using functional magnetic resonance imaging found that three non-responsive patients could follow commands and communicate through selective auditory attention. The study suggests that this technique assesses basic human cognition, including reasoning and information processing.
Researchers at the University of Adelaide discovered that dragonflies can lock onto one visual target while ignoring others, a phenomenon similar to selective attention in humans. This finding has significant implications for neuroscience and engineering applications.
Researchers found that selective attention increases both neural gain and feature selectivity of the human auditory cortex. The study used electroencephalographic event-related potentials to measure task performance in healthy volunteers, revealing a complementary mechanism to existing explanations.
