Popis: | Electroencephalography is a long-established technique and remains a crucial diagnostic tool in epilepsy. The high temporal resolution of EEG allows the detection of transient events, such as spikes, which are often an important feature in patients with epilepsy. However, it has low spatial resolution. Functional magnetic resonance imaging (fMRI), first demonstrated in 1990, with its high spatial resolution and noninvasiveness, has had a substantial impact on functional imaging. Combined EEG and fMRI promises to be a tool with all the desirable features of both individual techniques. EEG recording in the MR environment (per-MRI |
