New research suggests environmental exposure to bisphenol A (BPA), a chemical commonly found in plastics and resins, could suppress a gene critical to nerve cell function and the development of the central nervous system. Exposure to BPA could predispose humans to a number of neurodevelopmental and other health disorders.
Comparing fMRI scans of human brains and those of rhesus monkeys, researchers believe they have new evidence which proves humans have unique cortical brain networks.
New insight obtained by studying the gait of cockroaches could provide valuable information on how biological systems stabilize. The research could help to develop more stable robots and provide doctors with better understanding on human gait abnormalities.
A new study argues that prolonged chemotherapy decreases the development of new brain cells, and disrupts ongoing brain rhythms in the part of the brain responsible for making new memories.
Linguistics and biology researchers propose a new theory on the deep roots of human speech. A new study suggests human language is a grafting of two communication forms found elsewhere in the animal kingdom: first, the elaborate songs of birds, and second, the more utilitarian, information-bearing types of expression seen in a diversity of other animals.
Researchers have found compelling evidence that older adults can eliminate forgetfulness and perform as well as younger adults on memory tests. The findings have intriguing implications for designing learning strategies for older adults.
Researchers combined genetic data with neuroimaging in order to identify genes associated with amyloid plaque deposits in Alzheimer's disease patients. The study is believed to be the first genome-wide association study of plaque deposits using a specialized PET scan tracer that binds to amyloid.
A new study suggest that along with amyloid deposits, white matter hyperintensities may be a second necessary factor for the development of Alzheimer’s disease.
Researchers upend a long-held view about the basic functioning of a key receptor molecule involved in signaling between neurons. The study describes how a compound linked to Alzheimer's disease impacts NMDA receptors and weakens synaptic connections between brain cells.
