Research in macaque monkeys suggests that each region carries out a distinct functional role.
The latest findings by researchers at the Cognitive Brain Mapping Laboratory of the RIKEN Brain Science Institute and researchers at the Department of Experimental Psychology of the University of Oxford, published in Science this week, shed light on the nature of these functional differences.
The researchers trained fourteen macaque monkeys to carry out a behavioural task based on the Wisconsin card-sorting test, often referred to as a ‘frontal lobe’ test on the basis that patients with any sort of lesion on their frontal lobe tend to do badly at it. The impact on the macaque’s performance of lesions to five regions of the macaque prefrontal cortex was analyzed, results revealing that each region carries out a distinct functional role.
The discovery of these roles implies the existence of multiple functional components underlying seemingly inseparable high-level actions behaviours, unravelling the mystery of adaptive behaviour in primates. The findings may also prove useful in the understanding and treatment of mental diseases such as schizophrenia, which are thought to arise from a functional disorder in the prefrontal cortex.For more information, please contact

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
