For quality psychophysiological data acquisition with Nexus, you'll want to ensure you have a range of supplies that facilitate accurate and reliable measurements. 

  1. EEG Gel: High-quality conductive gel is essential for establishing a good connection between the electrodes and the scalp, ensuring optimal signal quality.

  2. Skin Preparation Gel or Paste: Before applying electrodes, it's crucial to prepare the skin to ensure good conductivity and reduce impedance. Skin preparation gels or pastes can help clean the skin and improve electrode-skin contact.

  3. Electrode Gel Syringes: Syringes can facilitate precise application of gel, especially in situations where electrodes need to be repositioned during the recording session.
