Psychologists observe larger striatal volumes in psychopathic adults

Leave a Comment / Health / By

A region of the forebrain known as the striatum tends to be larger in psychopathic individuals, according to new neuroimaging findings published in the Journal of Psychiatric Research. “We were interested in studying the neurobiological underpinnings of psychopathy. Specifically, although many researchers have studied psychopathy, there is little known about the involvement of this brain …

Astronomers Discover Evidence for Most Powerful Pulsar in Distant Galaxy

Astronomers Discover Evidence for Most Powerful Pulsar in Distant Galaxy

Leave a Comment / Science / By

As the shell of explosion debris from the supernova expands over a few decades, it becomes less dense and eventually becomes thin enough that radio waves from inside can escape. This allowed observations by the VLA Sky Survey to detect bright radio emission created as the rapidly spinning neutron star’s powerful magnetic field sweeps through …

Humans Can Learn to ‘Echolocate’ in Just 10 Weeks, Experiment Shows

Leave a Comment / Health / By

With enough training, most humans can learn how to echolocate, using their tongue to make clicking sounds and interpreting the echoes that come back, reflected from the surrounding environment.   In as few as 10 weeks, researchers have been able to teach participants how to navigate obstacles and recognize the size and orientation of objects …

Why do we get a buzz from being in large groups at festivals, jubilees and other public events? According to the social brain hypothesis, it’s because the human brain specifically evolved to support social interactions. Studies have shown that belonging to a group can lead to improved wellbeing and increased satisfaction with life.   Unfortunately …

AI Detects Autism Speech Patterns Across Different Languages – Neuroscience News

Leave a Comment / Health / By

Summary: Machine learning algorithms help researchers identify speech patterns in children on the autism spectrum that are consistent between different languages. Source: Northwestern University A new study led by Northwestern University researchers used machine learning—a branch of artificial intelligence—to identify speech patterns in children with autism that were consistent between English and Cantonese, suggesting that …
