Researchers used a rare brain procedure to document how the human brain computes grammar and produces words. The study found that distinct linguistic processes are computed within small regions of Broca's area, separated in time and partially overlapping in space.
Researchers developed a blood test to measure progranulin levels, predicting the risk of frontotemporal dementia (FTD) in patients. A shortage of progranulin leads to brain cell death, causing FTD, and this test can detect it before symptoms appear.
Researchers found that the left inferior frontal gyrus (LIFG) is necessary to resolve word competition during speech. This brain region, including Broca's area, is responsible for aspects of speech production and language processing.
Researchers found that low-income children's brains function differently from those of high-income peers, with detectable differences in prefrontal cortex response to visual stimuli. This study provides a direct measure of brain activity and sheds light on the impact of socioeconomic status on brain development.
Scientists report that a simple decision-making task does not involve the frontal lobes, instead relying on the parietal lobe to process sensory information and control responses. This finding challenges the traditional view of human decision-making as willful acts, suggesting that many decisions may be driven by automatic processes.
Researchers found that chimpanzees activate the same brain region as humans when producing communicative signals, suggesting a shared neural basis for language. The study suggests that this common ancestor may have possessed a 'language-ready brain,' with tremendous plasticity allowing for development of complex communicative signals.
Research suggests that neurons in the frontal lobe encode economic value in a 'menu invariant' way, enabling transitive preferences. This finding provides a key insight into the neural circuits underlying decision-making and may shed light on choice deficits associated with frontal lobe damage.
Researchers found that people with damage to their left frontal lobe are more likely to correct mistakes, while those with right-brain damage struggle to track changing task rules. This study highlights the crucial role of self-monitoring functions in everyday situations.
Researchers tracked brain activity in newborns, 6-month-olds, and one-year-olds using magnetic field technology. The study found that the areas responsible for listening and speaking in the brain are linked by age, indicating that infants form connections between perception and production of speech through experience.
Broca's area plays a crucial role in organizing actions and processing hierarchical structures, according to researchers Etienne Koechlin and Thomas Jubault. Their experiments found that this executive function is distinct from the organization of temporal sequences of actions.
Researchers found that older individuals with less white matter in the frontal lobes struggle to focus on tasks. The study used functional magnetic resonance imaging (fMRI) to examine brain structure and activation in individuals aged 19-87.
Researchers found that older adults' brains have trouble filtering out distracting information, leading to memory impairment. The study provides a new diagnostic tool for attention and memory problems in both young and old individuals.
Researchers have discovered that nonlinguistic monkeys have an area comparable to Broca's area, which is responsible for controlling oral and facial actions. This finding suggests that Broca's area may have evolved to control certain aspects of the speech act in humans.
Israeli psychologists studied participants with prefrontal-lobe damage and found they struggled to comprehend sarcastic messages. The researchers propose a neural network for processing sarcastic utterances, highlighting the importance of integrating social/emotional context with literal language.
The study reveals that both nature and nurture are essential for developing flexible self-control. The computer model demonstrates how the prefrontal cortex learns from life experiences to apply rules and strategies in new situations.
Research suggests that higher education helps older adults compensate for brain pathology and maintain cognitive function by engaging the frontal cortex. The study found a correlation between years of education and increased activity in the frontal lobes of older adults.
Researchers discovered a new gene, GPR56, responsible for bilateral frontoparietal polymicrogyria, a genetic disorder affecting brain development. The study suggests GPR56 may have played a key role in the evolution of the frontal lobes and human cognitive function.
A study using MRI technology found significantly higher levels of excitatory neurotransmitter glutamate and lower levels of inhibitory neurotransmitter GABA in the frontal region of children with ADHD. This imbalance may contribute to poor impulse control and other behavioral issues associated with the condition.
A study published in BRAIN found that frontal lobe damage can lead to inconsistent performance, even on simple tasks, with effects varying across brain regions. The researchers identified specific areas of the frontal lobes responsible for increased variability, shedding light on the mechanisms underlying this phenomenon.
A woman with frontotemporal dementia transforms her painting style from realistic to more expressive and emotionally charged as her language abilities decline. Her artwork showcases an intense emotional and impressionistic style, revealing the release of frontal lobe functions involved in social restraints.
Chronic alcoholism damages the cerebellum and frontal lobes, leading to motor deficits that persist even after long-term abstinence. Functional magnetic resonance imaging (fMRI) reveals that alcoholics' brains compensate for damage by recruiting new brain regions to perform simple tasks.
A Canadian study found that older adults tend to remember general facts about life events, while younger adults focus on specific details. The findings may relate to subtle brain differences associated with aging.
A small region in the frontal lobe is selectively activated when an individual intends to make a particular action. This finding helps explain why individuals with frontal lobe damage often have problems making decisions and act impulsively.
Studies suggest that attention can be broken down into three distinct processes: maintaining readiness, setting response thresholds, and filtering out distractions. The researchers' findings provide a more specific understanding of attentional disorders and their relation to frontal lobe injuries.
Researchers at Columbia University Irving Medical Center discovered that estrogen therapy improves consistency in older women, a key indicator of cognitive function. The study, which involved postmenopausal women taking hormone replacement therapy, found that estrogen users performed more consistently than those not taking the hormone.
A new study found that damage to the right prefrontal cortex, a small area in the brain's frontal lobes, is linked to impaired mentalizing, or understanding others' mental states. This deficit can affect empathy, sympathy, and social interactions.
A new study found that individuals with right anterior frontal damage struggle to appreciate written and verbal jokes and funny cartoons. Instead, they prefer silly slapstick humor, which is often illogical and absurd, such as The Three Stooges.
Researchers found that famous faces activate both sides of the brain, whereas unfamiliar faces only activate the right side. This suggests that paying attention to a person's name and face can improve memory recall.
A new study finds that when remembering words, the brain activates the left side, while unfamiliar faces are processed by the right. However, both sides become active for objects with names.
