BRAINY CHIMPS Some modern chimps have brain surface features that were thought to have signaled humanlike brain evolution in hominids from as early as 3 million years ago, scans suggest.
Hurst and Ralph Holloway of Columbia University led a team that laser scanned the inside surfaces of several partial H. naledi skulls to create virtual casts, or endocasts, of brain surfaces.
MRIs of eight living chimps reveal substantial variability in the shape and location of certain features on the brain surface.
While other neuroscientists have used functional magnetic resonance imaging (fMRI) and electroencephelography (EEG) to record activity in the thinking brain, the UC Berkeley scientists employed a much more precise technique, electrocorticograhy (ECoG), which records from several hundred electrodes placed on the brain surface and detects activity in the thin outer region, the cortex, where thinking occurs.
