It is well known that dynamical systems posed near a second order
phase transition generate a bewildering variety of flexible behavior,
associated with the abundance of metastable states at the critical
point. This universal feature led us to argue, since the last
millennium, that the most fundamental cognitive properties of the
functioning brain are only possible because it is spontaneously
located at the border of such instability. We review the motivation
and then describe recent experimental results, both in health and
disease, at various brain scales ranging from a few millimeters up to
the entire cortex. Finally we will discuss which aspects of the mind
dynamics can be usefully explained in terms of critical phenomena, as
well as the lesson and implications for building emerging intelligent
devices.
