How cognitive intelligence is a whole brain phenomenon

An international collaborative study led by researchers from the NUI Galway provides findings on the neural basis of intelligence, otherwise known as general cognitive ability (IQ).advertisement This new research uses an imaging technique called diffusion tensor imaging (DTI) to provide an insight into how small variations in this wiring system is associated with differences in […]

Device brings silicon computing power to brain research and prosthetics

While brain-machine interface devices already exist — and are used for prosthetics, disease treatment and brain research — this latest device can record more data […]

Ritalin and similar medications cause brain to focus on benefits of work, not costs

Common assumption has long held that Ritalin, Adderall and similar drugs work by helping people focus.advertisement Yet a new study from a team led in part by Brown University researchers shows that these medications — usually prescribed to individuals diagnosed with attention deficit hyperactivity disorder, but often used by otherwise healthy people as a “study […]
