Researchers have found that when our minds wander, our moods tend to suffer.

Why Mind Wandering Can Be So Miserable, According to Happiness Experts

We still don’t know why our minds seem so determined to exit the present moment, but researchers have a few ideas

Patients wear a NIRS apparatus—typically a neoprene helmet with dozens of optical sensors sticking out of it.

A new use for brain-computer interfaces gives insight to life with ALS

This is a pyramidal neuron, so named for the pyramid-shaped body at the center of this drawing, from the cerebral cortex of a human. This outermost layer of the brain integrates information from sensory organs, commands movements and is the hub for higher brain functions, such as consciousness. In his drawing, Cajal gives the branches or dendrites different weights to show how the neuron extends in three-dimensional space. It’s likely that this represents a sort of idealized portrait of a pyramidal neuron, a synthesis of many observations.

Abstract artist Wassily Kandinsky, who may have been a synesthete, once said: "Color is the key. The eye is the hammer. The soul is the piano with its many chords. The artist is the hand that, by touching this or that key, sets the soul vibrating automatically."
