Lab Guide


FreeB is a collection of simple designs for recording chambers, electrode modifications, stimulating probes, and other peripheral devices for the physiology and neurobiology laboratory.  They range in design originality from vaguely clever to "well . . duh!".  At any rate, they are comparatively inexpensive to build, in many cases effectively replace or significantly enhance more expensive commercially available alternatives, and are not overtly dangerous to use.  Descriptions, rough construction guides, and parts lists are under development for this site and/or free upon request.
