One variation of a system for locating electrodes on a head of a user includes a headset defining a set of electrode bodies elastically interconnected by a unique set of spring elements configured to locate the set of electrode bodies at electrode positions of the international 10-20 standard, irrespective of the size of the head of the user. The spring elements are configured to carry electrical signals between interconnected electrode bodies and ultimately to a controller. An electrode tip is mechanically and electrically coupled to each electrode body. The electrode tip comprises a thin conductive probe mounted at the distal end of an elastic beam and is configured to extend from a base of the electrode tip, bypass hair, and electrically couple to the head of the user, and an insulative boss, configured to rest on and transfer the weight of the headset to the head of the user.

A modular electroencephalogram (EEG) cart designed for hospital use, characterized by its versatility and ease of use is disclosed. The EEG cart features a wheeled frame with a top surface to aid technicians during procedures. A detachable technician panel, equipped with multiple drawers and a keyboard tray, is oriented for convenient access by the technician. Alongside, a cable recess panel with numerous hooks allows for efficient cable management and ease of cart transport. On the opposite side, an IT panel is installed, providing access to internal compartment for maintenance and IT serviceability. Facing the patient, a patient panel with pull-out trays readily available to hold medical equipment necessary for patient treatment. An upward-extending camera neck designed to securely hold both a monitor and a camera, for monitoring EEG procedures is also typically included. The modular cart streamlines EEG operations with its ergonomic design and functional features.

An electrode holder structure and an electroencephalogram cap are provided. The electrode holder structure includes a base, where multiple clamping jaws are disposed circumferentially and the clamping jaws are enclosed to form an accommodation area; an electrode holder, disposed in the accommodation area and fixedly clamped by multiple clamping jaws to form the electrode holder structure. Multiple clamping jaws are disposed circumferentially around the base, and at least one electrode holder is disposed in the multiple layers of accommodation areas formed by multiple clamping jaws, so as to realize stacking disposal of the electrode holder and the seat and improve the entire generality.
