When a mouse sweeps a single whisker across a textured surface, a tight cluster of neurons in its brain lights up within milliseconds. That cluster sits inside a grid of cortical columns, each one ...

The passage of time is sensed, perceived, and experienced, but—unlike for touch, vision, hearing, and olfaction—there exist no sensory receptors for time. This fact has long tantalized neuroscientists ...

The cerebral cortex processes sensory information via a complex network of neural connections. How are these signals modulated to refine perception? A team from the University of Geneva (UNIGE) has ...

Under propofol general anesthesia, sensory input still reaches the brain, but signals do not spread. A new study suggests consciousness requires cortical regions to all be 'on the same page.' General ...
