ATIC group of Universidad de Malaga has a laboratory in which to carry out research activity with specialized equipment and material. The laboratory, shown in Figure 1 (a), is located in the E.T.S.I. Telecommunication of the University of Malaga. The equipments have been acquired with the funding from multiple research or industrial projects.
Specialized EEG and NIRS Measurement Equipment:
Four complete systems for the acquisition of electroencephalogram (EEG) signals, actiCHamp Plus from Brain Products are available. With these systems, up to 96 EEG channels can be recorded in 4 people at the same time, simultaneously and synchronized between the 4 subjects and also synchronized with the stimulus or activity the four subjects are carrying out. A close illustration of the EEG equipment and EEG cap appears in Figure 1 (c).

Figure 1 (b) shows the four equipments placed in the EEG recording room. Figure 1 (c) show a detail of one of the caps with 96 EEG channels. The computers that collect the EEG signal are located outside the room. The computer inside the EEG room can be employed for stimuli presentation. A specific interface allows the synchronization of the four recording systems and computers with each other and with the development of the activity during which the EEGs are recorded.
The system is modular and configurable, so that, if required, the number of EEG channels can be increased until 160 channels in the appropriate configuration in two people simultaneously or up to 128 channels in three people.
NIRS kits are also available, including:
- A fixed NIRS measuring device with 32 sources x 32 LED light detectors, compatible with EEG. This system will be expandable to at least 64 sources and 32 detectors.
- Two portable NIRS measurement equipment. Each NIRS portable measurement equipment must include at least 16 light sources + 16 light detectors and be compatible with EEG measurements. The two computers can be connected to each other, so that they can be used as a single 32x32 system, or as two totally independent systems of at least 16x16.
The EEG caps and electrodes in this system are compatible with the capture of NIRS signals (Near Infrared Spectroscopy), so that, in the same cap, both EEG electrodes and NIRS optodes can be placed that allow the simultaneous use of both techniques on the same subject.
