NeuroCognitive Imaging Laboratory. Cognitive neuroscience. Cognitive neuroscience is an academic field concerned with the scientific study of biological substrates underlying cognition,[1] with a specific focus on the neural substrates of mental processes. It addresses the questions of how psychological/cognitive functions are produced by the brain. Cognitive neuroscience is a branch of both psychology and neuroscience, overlapping with disciplines such as physiological psychology, cognitive psychology and neuropsychology.[2] Cognitive neuroscience relies upon theories in cognitive science coupled with evidence from neuropsychology, and computational modeling.[2] Due to its multidisciplinary nature, cognitive neuroscientists may have various backgrounds. Other than the associated disciplines just mentioned, cognitive neuroscientists may have backgrounds in these disciplines: neurobiology, bioengineering, psychiatry, neurology, physics, computer science, linguistics, philosophy and mathematics.

Historical origins[edit] Consciousness[edit] Neurocognitive. Neurocognitive functions are cognitive functions closely linked to the function of particular areas, neural pathways, or cortical networks in the brain substrate layers of neurological matrix at the cellular molecular level. Therefore, their understanding is closely linked to the practice of neuropsychology and cognitive neuroscience, two disciplines that broadly seek to understand how the structure and function of the brain relates to perception defragmentation of concepts, memory embed, association and recall both in the thought process and behaviour.

A neurocognitive deficit is a reduction or impairment of cognitive function in one of these areas, but particularly when physical changes can be seen to have occurred in the brain, such as after neurological illness, mental illness, drug use, or brain injury.

Posted at 10:21 AM ET, 05/13/2011 May 13, 2011 02:21 PM EDT TheWashingtonPost New research shows that sleep deprivation has worse effects than just the occasional mistake or error—and can cost organizations just as much, if not more.

(MATT MCCLAIN - THE WASHINGTON POST) As we all know, sleep deprivation can lead to exhaustion-fueled mistakes in the workplace, whether they be a simple typo in a quarterly report or life-threatening errors while operating machinery. (Or as the FAA discovered recently, embarrassing front-page headlines about workers napping on the job.) But according to two business school professors, it can make people more unethical too. How does this happen? And why does this matter for leaders? The numbers the two professors cite in their paper are startling.

Christian and Ellis show that sleep deprivation has worse effects than just the occasional mistake or error—rude behavior and deviance can cost organizations just as much, if not more. More from On Leadership:
