Neuroscientists have identified flexible modules in the prefrontal cortex that can be reused to perform various tasks. The discovery supports the theory of compositionality, where cognitive building blocks can be flexibly combined to generate new behaviors.
A new study from UC Berkeley reveals that the depth of small grooves on the brain's surface is correlated with increased connectivity between regions involved in reasoning. The researchers found that these tertiary sulci, unique to humans, may help explain individual differences in cognitive performance and serve as diagnostic indicato...
Research using fNIRS found that young children's ability to appreciate humor varies with age and sex. The study suggests differences in brain activity between boys and girls, as well as developmental stages, when it comes to recognizing humor.
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.
Neuroscientist Hagoort challenges the classical view that language is confined to two major areas in the left half of the brain, instead proposing a multi-brain-network view that incorporates multiple regions and operations, including those shared with other cognitive domains like music and arithmetic.
Researchers used monkey parietal lobe studies to find the brain distinguishes causes of errors for adaptation. Motor errors are corrected using signals from Brodmann area 5, while target errors are corrected with signals from Brodmann area 7.
Scientists have updated the traditional brain map of language comprehension by discovering a new location for word comprehension in the left anterior temporal lobe. Sentence comprehension is found to be distributed widely throughout the language network, contradicting previous theories. The study provides a more precise target for futu...
Researchers at the University of Wisconsin-Madison have tracked electrical activity in brains during imagination and reality, revealing opposite directions of information flow. During imagination, signals move from the parietal lobe to the occipital lobe, while in reality, they flow in the opposite direction.
Researchers at Carnegie Mellon University discovered that when one brain area is injured, a 'back-up' team of secondary brain areas immediately activates, replacing the unavailable area and its confederates. This allows individuals to continue functioning after key brain areas have been damaged.
A recent study by MU researchers suggests that the brain features a complex network of areas responsible for spiritual experiences, rather than a single 'God spot'. The study found that aspects of spiritual functioning are related to increased activity in the frontal lobe and decreased activity in the right parietal lobe.
Researchers have rewritten the textbook on the location of the brain's speech processing center, discovering it is located in the left temporal lobe and superior temporal gyrus. The new findings suggest that language originated between monkeys and humans closer than previously thought.
Researchers translated brain signals into words using two grids of 16 microelectrodes implanted beneath the skull but atop the brain. The study showed that the method can distinguish between brain signals for each word, with an accuracy rate of 76-90%, demonstrating proof of concept.
A University of Iowa study links sex differences in brain structure, particularly in the parietal lobe, to variations in spatial skill test performance. Women's thicker cortexes are associated with poorer mental rotation ability, while men's larger parietal lobe surface area is related to better performance.
Researchers at UCL induce dyscalculia in normal subjects using TMS, finding a causal link between right parietal lobe malfunction and the math learning disorder. This breakthrough study has implications for diagnosis and treatment, potentially leading to earlier interventions and more effective remedial teaching.
Two studies in Neuron shed significant light on how the brain processes numerical information and how it develops in children. The research found that the parietal cortex activates during perception of both abstract quantities and numerical symbols, suggesting an important role for this region in processing quantitative information.
Researchers found that different brain pathways handle mental rotation and object recognition tasks, indicating distinct neural circuits. The ventral pathway is involved in object identity, while the dorsal pathway is linked to spatial location.
