Quantitative characterization of unit response in the visual system

A quantitative approach to characterization of unit response in the visual system was proposed. Temporal parameters of response were analyzed by post stimulus time-histograms obtained from point visual stimulation. Explicit temporal intervals were chosen to coincide with discrete response components. By calculating net firing rate within these intervals as a function of stimulus position, quantitative receptive field maps were constructed. To estimate response between stimulated matrix mesh points, a general contouring program was described. Latency, and synchronicity — a logarithmic probability function sensitive to temporal consistency of response — were also mapped as functions of stimulus position.
