Porsche take EEG marketing bollocks to the next level

The arrival of cheap, portable EEG (electroencephalography) equipment in the last ten years has been a bit of a mixed blessing. On the one hand, you have initiatives like the… 502 more words


Functional Magnetic Resonance Imaging

fMRI basics

Functional magnetic resonance imaging, or fMRI, is a technique that provides information on brain activity. It works by detecting the changes in blood oxygenation and flow that occur in response to neural activity – when a brain area is more active it consumes more oxygen and to meet this increased demand blood flow increases to the active area. 2,007 more words



MEG basics

The magnetoencephalography or MEG is similar to EEG, however it measures changes in the associated magnetic fields of the neurons generating electrical potentials. Because the skull is transparent to magnetic fields, however, the spatial resolution of MEG is said to rival that of fMRI while maintaining the superior temporal resolution of EEG. 62 more words



EEG basics

Electroencephalography, or EEG, is the non-invasive measurement of the electrical activity of the brain by recording from electrodes placed on the scalp. When neurons are active, they fire action potentials, and send messages in the form of neurotransmitters to other neurons. 696 more words


Positron Emission Tomography

PET basics

Positron Emission Tomography, or PET, uses trace amounts of short-lived radioactive labeled molecules, usually called tracers or radio-tracers, which are injected into bloodstream to map functional processes in the brain. 2,001 more words


Diffusion Weighting Imaging

DWI basics

Diffusion Weighting Imaging, or DWI, also referred to as diffusion tensor imaging or DTI, is a MRI method that maps water molecule diffusion patterns and can be done on most research MRI scanners. 4,144 more words


Magnetic Resonance Imaging

MRI basics

Magnetic Resonance Imaging, or MRI, often called structural MRI or T1-weighted images, is a non-invasive, painless and safe medical procedure that uses magnetism, radio waves, and a computer to produce images of body structures and, particularly of interest, of brain tissue.  2,511 more words
