Inside the brains of mice and men alike, a relatively big football-shaped region called the thalamus acts like a switchboard, providing the prefrontal cortex, the part that does abstract thinking and...
Early involvement of prefrontal cortex in visual bottom-up attention
The authors found that, when monkeys detected a salient stimulus defined purely by bottom-up factors, neurons in the dorsolateral prefrontal cortex represented the stimulus no later than those in the...
Study: Brain imaging can predict how intelligent you are
When it comes to intelligence, what factors distinguish the brains of exceptionally smart humans from those of average humans? Size and prefrontal cortex activity contribute, but new research from...
(Medical Xpress) -- A clue to understanding certain cognitive and mental disorders may involve two parts of the brain which were previously thought to have independent functions, according to a McGill...
Long-term hormone treatment increases synapses in rat prefrontal cortex

The Complexities Of Self-Awareness In Humans
Ancient Greek philosophers considered the ability to "know thyself" as the pinnacle of humanity. Now, thousands of years later, neuroscientists are trying to decipher precisely how the human brain con...
Confidence in value-based choice
This study examines the neural coding of decision confidence when human subjects make value-based economic choices, and finds that signals of explicit confidence are encoded in the activity of ventrom...

Network architecture of the long-distance pathways in the macaque brain.
Understanding the network structure of white matter communication pathways is essential for unraveling the mysteries of the brain's function, organization, and evolution. To this end, we derive a uniq...
