Abstract
The use of impulse inputs for characterizing neural “signals” that are embedded in electroencephalographic EEG “noise” is reviewed in the context of linear systems analysis. Examples are given of the use of linear and nearly linear basis functions with statistics for measurement of neural activity patterns of single cells and populations, with emphasis on the relations between microscopic and macroscopic activity, including measurement of local mean fields and description of the transfer of microscopic sensory information to the macroscopic level of perception and then back to microscopic cortical output by action potentials. Some elements of nonlinear dynamics are introduced that are needed to understand the emergence of low-dimensional aperiodic activity in sensory cortex, and its possible uses for the operation of Hebbian synapses during the learning of new generalization gradients.
