    • Dynamics of electroencephalogram entropy and pitfalls of scaling detection 

      Ignaccolo, M; Latka, M; Jernajczyk, W; Grigolini, P; West, BJ (2010)
      In recent studies a number of research groups have determined that human electroencephalograms (EEG) have scaling properties. In particular, a crossover between two regions with different scaling exponents has been reported. ...

    • Spontaneous brain activity as a source of ideal 1/f noise 

      Allegrini, Paolo; Menicucci, Danilo; Bedini, Remo; Fronzoni, Leone; Gemignani, Angelo; Grigolini, Paolo; West, Bruce J; ... (8 authors) (2009)
      We study the electroencephalogram (EEG) of 30 closed-eye awake subjects with a technique of analysis recently proposed to detect punctual events signaling rapid transitions between different metastable states. After ...
