ever-changing manner. The effect of a signal transmitted synaptically from one neuron to another can vary enormously, depending on the recent history of activity at either or both sides of the synapse, and such variations can last from milliseconds to months. Activity-dependent changes in synaptic transmission arise from a large number of mechanisms known collectively as synaptic plasticity. Sy...

277 Although retinal input relayed through the lateral geniculate nucleus (LGN) of the thalamus clearly drives responses in the primary visual cortex (V1), LGN afferents account for only a small fraction of the synapses onto V1 neurons1–7. The primary source of synaptic input to neurons in primary visual cortex, at least in terms of numbers, is excitatory input from other nearby cortical neuron...

Higher Lawrence configurations

Any configuration of lattice vectors gives rise to a hierarchy of higher-dimensional configurations which generalize the Lawrence construction in geometric combinatorics. We prove finiteness results for the Markov bases, Graver bases and facet posets of these configurations, and we discuss applications to the statistical theory of log-linear models.
