Menu design key to increased wine sales and customer satisfaction

Ever since America's oldest restaurant, the White Horse Tavern in Rhode Island, opened its doors in 1673, restaurateurs have been trying to keep their customers happy while increasing profits. Wine has always been a solid ...

Brain imaging shows what happens when we question fake news

Misinformation on social media may seem like an intractable problem, but a new study from business researchers at The University of Texas at Austin shows that asking a single question can be a powerful weapon against fake ...

Waste coffee grounds could someday help detect brain waves

There's nothing like a steaming cup of joe to give your morning a quick boost. Now, there's yet another reason to love the beverage. Today, researchers report the first application of used coffee grounds as environmentally ...

Nanomodulators of light on optical micro-probes to study the brain

When it comes to recording and stimulating brain activity, scientists can rely on a formidable tool: light. An international research team, coordinated by IIT- Istituto Italiano di Tecnologia (Italian Institute of Technology), ...

How recess helps students learn

As parents and schools seek to support students' social and emotional needs—and teach them what they need to learn—some education leaders are missing one particularly effective opportunity.

The neuronal mechanism behind motivation

Our actions are motivated by the goals we want to achieve. However, little is known about the mechanism in our brains that allow us to make the right decisions to reach our goals. Researchers in the Lüthi lab now identified ...

Flies navigate using complex mental math

The treadmills in Rachel Wilson's laboratories at Harvard Medical School aren't like any you'll find at a gym. They're spherical, for one, and encased in bowling ball–sized plastic bubbles. They're also built for flies.

Electroencephalography (EEG) is the recording of electrical activity along the scalp produced by the firing of neurons within the brain. In clinical contexts, EEG refers to the recording of the brain's spontaneous electrical activity over a short period of time, usually 20–40 minutes, as recorded from multiple electrodes placed on the scalp. In neurology, the main diagnostic application of EEG is in the case of epilepsy, as epileptic activity can create clear abnormalities on a standard EEG study. A secondary clinical use of EEG is in the diagnosis of coma and encephalopathies. EEG used to be a first-line method for the diagnosis of tumors, stroke and other focal brain disorders, but this use has decreased with the advent of anatomical imaging techniques such as MRI and CT.

Derivatives of the EEG technique include evoked potentials (EP), which involves averaging the EEG activity time-locked to the presentation of a stimulus of some sort (visual, somatosensory, or auditory). Event-related potentials refer to averaged EEG responses that are time-locked to more complex processing of stimuli; this technique is used in cognitive science, cognitive psychology, and psychophysiological research.
