Researchers report Alzheimer's disease and other neurodegenerative disorders can be confirmed in living patients by specific biomarkers in cerebrospinal fluid.
Removing the wisdom teeth can improve a person's taste perception by up to ten percent.
Children from lower-income families and who greater adversity develop their first permanent molars before their peers with less stressful backgrounds.
HIV infection prevents myelin-associated oligodendrocytes from maturing, this, in turn, hampers white matter production in the brain.
A new theory suggests the brain understands the level of activation required from a sensory input and corrects for it, leaving behind a signal for familiarity.
When we imagine the outcome of future events, two sub-networks of the brain become active. One of the sub-networks focuses on creating the new event in our imagination, the other evaluates whether the event is positive or negative.
Researchers propose a new theory of what happens in the brain when we experience familiar seeming visual stimuli. The theory, dubbed sensory referenced suppression, suggests the brain understands different levels of activation expected for sensory input and corrects for it, leaving behind the signal for familiarity.
Impaired motor function, such as that experienced by Parkinson's patients, appears to influence the perception of art, researchers report.
People with schizophrenia and other neuropsychiatric disorders may have a more permissive blood-brain barrier which allows the immune system to become more actively involved in the central nervous system. The resulting inflammation may contribute to the clinical manifestation of psychosis-like symptoms.
A new visual-based tool may help to reduce social disparities at a critical point of child development for a more accurate assessment of autism.
A single head injury can increase the risk of developing dementia, especially in women. Suffering more than one head injury increases the risk further, a new study reports.
Neuroimaging revealed when people saw an anomalous face, the fusiform gyri and amygdala showed significant neural responses. Activity in a region of the left amygdala, which correlated with less pro-social responses to the anomalous face, appeared to relate to the participant's belief about justice in the world and their degree of empathetic concern.
