Abstract

The understanding of how neurons interact in the visual cortex and what types of neurons are responsable for each interaction are still open questions. In order to analyse such problem, the spiking activity of neurons in the central visual pathway of awake owls was analyzed with Principal Component Analysis (PCA) and clustering techniques. Further analysis using kernel representation revealed the existence of two large groups of neurons with distinguishable behavior.
