Recurrent neural networks within the human frontal cortex may be responsible for decision making, language, and movement, researchers report.
People show a decrease in motivation to exert effort or work when feeling fatigued. Motivation can be restored if people are allowed a short rest, however for those with long-term fatigue, motivation does not improve following a short-term period of rest.
Study reveals a surprising level of similarity in brain structure and development between humans and other primates.
Neuroimaging study reveals structural and functional differences in brain areas associated with emotional regulation in those with personality traits linked to psychopathy or antisocial personality disorder.
Combining neuroimaging data with artificial intelligence technology, researchers have identified a complex network within the brain that comprehends the meaning of spoken sentences.
Smaller brain volumes in the cingulate cortex, insular, and superior frontal cortex predict an increased likelihood of developing PTSD three months after brain injury.
Early-life exposure to antibiotics may impact brain signaling pathways associated with social behavior and pain regulation. Young mice treated with antibiotics had reduced expression of receptors that mediate endorphin, oxytocin, and vasopressin signaling in the frontal cortex.
A new study reveals the role the claustrum plays in cocaine addiction. Inhibiting claustral neurons prevented behavioral responses to cocaine in mouse models of addiction.
Study identifies a different set of individual neurons in the medial frontal cortex that is responsible for memory-based decision making. The findings have implications for the treatment of Alzheimer's disease, schizophrenia, and other disorders associated with problems in cognitive flexibility.
Mouse study reveals slow-wave brain activity, which is indicative of sleep and resting states, is controlled by the claustrum. The synchronization of active and silent states across the brain via the slow waves contributes to consciousness.
Heart insufficiency has a negative impact on gray matter in the brain. Weak heart function was linked to decreased gray matter in areas of the brain associated with memory and learning, including the hippocampus and parietal medial cortex. This may increase the risk of Alzheimer's disease.
Lower levels of the circular RNA in the frontal cortex appears to be correlated with earlier onset of schizophrenia symptoms.
