The Labs

This has a control/preparation area and two recording booths, plus a post-processing centre with 3 PCs running Scan Edit licences. Each of the recording booths contains light-control, video monitoring, and 2-way (subject-to-experimenter) intercom. Data acquisition is carried out via 32-channel digital signal processing hardware and software packages from Associative Measurement (AMLAB) designed and built in Sydney, Australia. AMLAB DAC1 amplifiers and AMLAB I hardware and software are used in booth 1, while booth 2 uses the DAC2 amplifiers and AMLAB II hardware and software. The flexible AMLAB data acquisition systems allow simultaneous recording of CNS and ANS measures. ANS and CNS physiological data from all recording labs can be processed in the post-processing centre.

This lab focusses on ERP investigations of inhibition (in both control and clinical children and adults) and is equipped with a 40-channel NuAmps recording system. Simultaneous skin conductance recording is also available.

This lab focusses on EEG/ERP investigations of clinical groups and is equipped with a 40-channel NuAmps recording system. Simultaneous skin conductance recording is also available. The lab also possesses sophisticated portable and ambulatory equipment to record psychophysiological measures (EEG, heart rate, and elecrodermal data) in ecological valid, real-life situations.

This currently uses the digital signal processing capabilities (with flexible graphical user interface) of additional AMLAB II systems to investigate EEG-ERP dynamics. The fine structure of EEG data recorded in any of the recording laboratories can be explored here.
