Researchers have discovered how two neocortical areas in the brain communicate with one another and found that their influence on each other changes over much faster timescales than previously thought.
Neuroscientists using MRI scans discovered that psychopathic people have a 10% larger striatum, a cluster of neurons in the subcortical basal ganglia of the forebrain, than regular people. This represents a clear biological distinction between psychopaths and non-psychopathic people.
Glycan, a special sugar protein, appears to play a significant role in the development of Alzheimer’s disease.
Genetic studies have offered clues, identifying genes associated with Autism Spectrum Disorder, but despite finding many pieces to the puzzle, scientists have not yet figured out how they all fit together, and why there is such wide variation in ASD symptoms. Now an international team of scientists report significant progress in understanding how the combined effects of rare mutations and common genetic variation determine whether a child will develop ASD.
Researchers identify the exertion level where aerosol particle emission increases exponentially, offering an explanation as to why exercise intensity may be linked to the transmission of infections.
The dopaminergic system appears to play an important but overlooked role in LSD’s effects on consciousness, according to new research published in the journal Psychopharmacology. The findings provide new insight into the neurophysiological mechanisms responsible for the unique effects of psychedelic drugs.
Finally this week, a new study has identified potential targets to develop a therapy that could prevent Alzheimer’s disease.
