  Physics deals with Newtonian particles described by position q and momentum
p. The precision of the simultaneous measurement of q and p is limited by the
uncertainty relation ruled by Planck's constant. From the uncertainty relation
all quantum consequences emerge, including entanglement. On the other hand,
Homoclinic Chaos (HC) , that consists of sequences of identical pulses,
unevenly spaced in time, entails a non-Newtonian description. Synchronization
of finite HC spike sequences (SFSS) display quantum features ruled by a
constant different from hbar, yielding entanglement. As a relevant example, we
describe how brain neurons generate HC voltage pulses. SFSS is the way two
different words coded as HC pulses compare their content and extract a
meaningful sequence by exploiting quantum entanglement that lasts over a
de-coherence time in the range of human linguistic processes.
