ATLAS Headboxes

Allows Buffered Recording and External Stimulus Delivery Simultaneously
through All Electrodes with Touch-Proof Connections

Designed for use with:

• ATLAS Cart
• MDR-50 Male-to-Male Tether Extension Cables

ATLAS Headboxes provide neurologists with the ability to record any electrode signal - scalp, intra-cranial macro, and microwires. Additionally, our unique active, high impedance buffer circuitry maintains signal fidelity and drastically reduces noise interference inherent in the clinical environment. A parallel touch-proof connector set accommodates external stimulator connections that speeds up manual cortical mapping procedures.

ATLAS Headbox

Signal Quality

  • Active buffers are stimulus-tolerant:
    up to +/- 15 volts (30 volt total)
  • Low noise buffers on all signals for improved
    signal quality - high fidelity microwires
  • Exact unity gain buffers maintain excellent
    CMR performance for noise and
    artifact rejection

Recording Capabilities

  • Record stimulus delivery and EEG after-discharges from all electrodes - amplifier inputs are not disconnected during stimulus delivery
  • Record scalp and intra-cranial electrodes with touch-proof connections

Applications and Use

  • Accommodates standard EEG recording routines
  • Facilitates surface recordings of spontaneous EEG and evoked response
  • Easily connect stimulators for cortical mapping procedures or research stimulus purposes
