summary = {They argue strongly for the role of cortical neurons as coincidence
detectors. They try to refute Shadlen and Newsome by saying that
not so many synaptic potentials are coming in at each neuron as S+N
assumed and that, furthermore, the low reliability of synapses makes
the number of synaptic events going thru to the postsynaptic neuron
even smaller. So, therefore, they argue, the argument of S+N is wrong
because it assumes that the 'amplitude' (I presume they mean frequency)
of the input and output of the neuron is the same, and this is not
true. I must admit I do not really understand this argumentation.
They also attack the balanced inhibition hypothesis. They argue that
inhibition is usually broader tuned than excitation and that therefore,
even if excit. and inh. happened to be exactly balanced for one particular
stimulus, this would change if a second stimulus would be added or
if the stimulus itself would change. Likewise, the observed oscillations
correspond to alternating inhibition and excitation. They argue,
that S+N should therefore respond in a regular fashion which is not
observed. }
