Cox K.J.A. and Adams P.R. (2009) Hebbian crosstalk prevents nonlinear unsupervised learning.
Front. Comput. Neurosci. 3:11. doi:10.3389/neuro.10.011.2009 PDF
This paper shows that in a popular
model of nonlinear Hebbian learning, there is a critical level of synaptic
update error beyond which the system is unable to extract any useful
information. This is the first evidence that a critical error threshold may well
be a limiting factor regarding learning in the cortex and supports our
contention that a large part of cortical circuitry is involved in error
correction by proofreading.

and Adams, P.R. Hebbian errors in learning: An analysis using the Oja
model. J. Theor. Biol.(2009), 258, 489-501
This paper explores with analysis and
simulations the role of Hebbian synaptic update error in the Oja Model, which is
a linear system. We find that error, as expected, degrades performance but that
there is no sudden breakdown, in contrast to the nonlinear case.
