A major goal of modern MRI research is to be able to image neural circuits in the central
nervous system. Critical to this mission is the ability to describe a number of important …

The action currents of a dendrite, peripheral nerve or skeletal muscle create their own
magnetic field. Many investigators have attempted to detect neural and dendritic currents …

A number of studies have now shown that direct detection of neuronal firing by MRI may be
possible. The optic nerve carries all visual information from the eye to the brain and is a …

The idea of using magnetic resonance imaging (MRI) to assess human brain activation
noninvasively, rapidly, and with relatively high spatial resolution, was, before 1990, pure …

Recently, there has been a growing interest in ultra-fast fMRI mapping. We are providing an
optimized pulse sequence method for a 2D line-scanning technique, allowing for the …

Abstract Lorentz Effect Imaging (LEI) is an MRI technique that has been proposed for direct
imaging of neuronal activity. While promising results have been obtained in phantoms and …

As more evidence is presented suggesting that the phase, as well as the magnitude, of
functional MRI (fMRI) time series may contain important information and that there are …

A functional magnetic resonance imaging (fMRI) method that focuses on neural magnetic
fields has great potential to detect neural activities more directly than the conventional …

This paper provides an overview on the basic principles and applications of
magnetoencephalography (MEG), a technique that requires the use of many SQUIDs and …

Ever since the very first measurements by Hans Berger, we know that the brain produces
rhythmic activity that can be measured by EEG. Since then, many different rhythmic …
