Laboratory for Speech Physiology and Motor Control - Facilities

The Laboratory for Speech Physiology and Motor Control is a designated research laboratory. The facilities include:

• Electromagnetic articulograph (Carstens Medizinelektronik) for motion tracking (200 Hz) of the jaw, tongue, and lips during speech and orofacial nonspeech movements
• Electromagnetic motion tracking (240 Hz) of arm, hand, and finger movements (Liberty, Polhemus)
• Camera-based 3D movement tracking system for the registration and analysis of speech and limb movements (Ariel APAS) and digital video capture card (Pinnacle Systems)
• Computer-controlled robot to generate force fields or perturbations during jaw and hand/arm movements (Phantom Premium 1.0; Sensable Technologies)
• BioSemi ActiveTwo EEG/EMG system with active electrodes for the registration of movement-related cortical potentials (Readiness Potential), auditory/visual/somatosensory evoked potentials, and electromyographic signals
• Grass Model 15 neurophysiological amplifier system with 15A54 quad amplifiers, electrode board, isolated power supply, and various types/sizes of electrodes for the registration of movement-related cortical potentials (Readiness Potential), evoked potentials, and electromyographic signals
• Custom workstation for the display of virtual visual targets in studies of reaching (including DLP projector, first-surface mirrors, and back-projection screen for display of targets and airsled systems for support of the arm on a glass worksurface).
• 3D virtual reality face mounted display (i-visor FX601)
• MeasurementComputing PCI DAS6402-16 64-channel, 16-bit, A/D D/A board
• Force/torque transducer for finger and mandibular applications (Nano 17, ATI-IA)
• Physiological A/D D/A system (Biopac MP100) with stimulator unit (Biopac STIM100) and data acquisition and analysis software (Biopac AcqKnowledge)
• Electroglottograph for the registration of vocal fold contact area
• Respiratory transducers for thoracic and abdominal movements (Grass F-RCT-A)
• Various hardware and software systems for the acoustic analysis and processing of speech and voice
• High-quality audio instrumentation including various wired and wireless microphones, two-channel preamp with digital output (ART), four-channel microphone mixer (Shure), four-channel headphones amplifier (Samson S-phone), CD recorder (JVC) and tape-decks (JVC, Teac)
• Custom-built electrogoniometers for the transduction of finger movements
• Laser disc player (Panasonic LX-121)
• Video Cassette Recorders and TV
• 12 networked desktop and laptop computers (Windows XP, Linux, Mac OS9, Mac OSX) with DVD+RW and CD-RW drives and laser printers
• X-ray microbeam data base and cineradiography database
• MATLAB and LabView software packages
• Custom-written and standard experiment control and stimulus presentation software packages for various speech and motor control experiments
• 7 ft x 7 ft sound booth (Industrial Acoustics)
