Headcap, Headcaps

The BioSemi headcap has been developed in cooperation with Dr. Peter Praamstra at the Behavioral Brain Sciences Center, University of Birmingham, United Kingdom. The headcap consists of an elastic cap with plastic, electrode holders. The cap itself does not contain electrodes. The cap is placed on the subject's head, and the electrode holders are filled with electrode gel with a syringe. Because of the active electrode setup, high electrode impedance's can be tolerated, so no skin preparation is required. Thus, the usual, unpleasant and time consuming scrubbing of the scalp after the paste is applied can be omitted. After the buttons are filled with paste, the active electrodes are plugged in the cap one by one. The procedure is fast and reliable (5-10 minutes for 32 channels), and allows high density EEG measurement with a minimum of preparation time and subject discomfort. Caps with a

, can be delivered straight from stock. The electrode position coordinates of standard BioSemi headcaps are downloadable. Since the electrode holders make the caps a little bit smaller, please order your caps half a size bigger. (so if you want a Medium cap, please order a Medium/Large cap). Standard, the caps have ear-slits for easy accessing of the ears. Surgical caps are available on demand. Different electrode layouts are possible on client specification. It is also possible to assemble your own cap layout. Caps are delivered complete with a 5" (12cm) velcro chin strap (7" strap is included starting from ML sizes). Information about infant head circumference sizes can be found on this page.
