Perception

Like a highway system, the vagus nerve branches profusely from your brain through your organs to marshal bodily functions, including aspects of mind such as mood, pleasure and fear.

Neuroscience research into people with aphantasia, who don’t experience mental imagery, is revealing how imagination works and demonstrating the sweeping variety in our subjective experiences.

The work of the neuroscientist Ishmail Abdus-Saboor has opened up a world of insights into precisely how much pleasure and pain animals experience during different forms of touch.

A mutant seedling revealed how plant tissues scatter incoming light, allowing plants to sense its direction and move toward it.

A five-year “adversarial collaboration” of consciousness theorists led to a stagy showdown in front of an audience. It crowned no winners — but it can still claim progress.

Consciousness, our experience of being in the world, is one of the mind’s greatest mysteries, but as the neuroscientist Anil Seth explains to Steven Strogatz, research is making progress in understanding this elusive phenomenon.

New experiments show that the brain distinguishes between perceived and imagined mental images by checking whether they cross a “reality threshold.”

Memories may affect how well the brain will learn about future events by shifting our perceptions of the world.

After decades of frustration, researchers have determined how an airborne scent molecule links to a human smell receptor.
