Psychophysiology

The psychophysiology lab studies how human react to various uni- and multisensory signals – visual, auditory and tactile stimuli. We assess human responses at different levels using subjective ratings, behavioral data, physiological and brain wave recordings. This data help us to understand human perception and cognition mechanisms, with particular stress on the novel methods for diagnosis and treatment of varios brain disorders (chronic pain, migraine, autism, depression, Alzheimer's disease)

 

Study topics include

  • affective chronometry (such parameters as the rise time to peak and the recovery time of the emotional waveform)
  • multisensory perception (sound, vision, touch)
  • multisensory interactions for emotional stimuli (custom sound and video databases are created)
  • sonification of EEG signals
  • neurofeedback using mixed reality environments
  • processing of eye-gaze in autistic children

Key infrastructure

  • Eye tracker (TOBII, X120)
  • Physiological measuring devices and sensors (g.Mobilab):
    • respiration sensor
    • facial electromiography (EMG)
    • electrodermal activity (EDA) sensors
    • 4-channel electrophysiology (EEG) recording capability
    • pulse sensor
    • electrocardiogram (ECG) recording capability
  • Dry EEG electrodes, ENOBIO (starlab)
  • Various visual displays (including HMD and 50 inch LCD and plasma monitors)
  • Various sound presentati (including stereo bone conduction headset, Oiido)
