Abstract: A first apparatus applies magnetic field pulses to a subject, a second apparatus records electric signals of the subject, wherein the electric signals are received as analog signals from the subject while the magnetic field pulses are being applied to the subject. The first apparatus has a generating unit for generating the magnetic field pulses, a first clock generator for generating a first clock, and a first control unit for triggering generation of the magnetic field pulses by the generating unit with a fixed repetition rate based on the first clock. The second apparatus has an analog-to-digital conversion unit for converting the analog signals to corresponding digital signals by sampling each of the analog signals with a sampling rate, a second clock generator for generating a second clock, and a second control unit for causing the analog-to-digital conversion unit to set the sampling rate based on the second clock. A synchronizing unit synchronizes the second clock with the first clock.

Abstract: Artifacts are removed from EEG signals by segmenting EEG data that are continuously recorded during an MR scan with respect to a time period based on the MR scan, thereby obtaining n temporally consecutive segments of EEG data. For each segment j of the n segments, it is determined whether movement is detected when the segment j is recorded. In the case of no movement, the segment j is selected for a template k. In case movement is detected, EEG data of segments of the n temporally consecutive segments which have been selected for the template k are averaged, thereby obtaining the template k, the template k is subtracted from the EEG data of the segments, k is incremented, and the segment j is selected for the template k.

Abstract: An electrode for detecting EEG signals comprises a body comprising a fixture on a first end of the body, and a sensor detachably held by the fixture, wherein the body has an external thread in a portion of the body extending from the first end of the body towards a second end of the body, and the sensor has a brush-like shape with pins protruding off the body. The electrode may be held by an attaching device for holding electrodes for detecting EEG signals, the attaching device comprising a strap including a plurality of holes for accommodating electrodes and a rotary closure connecting a first end of the strap and a second end of the strap.
