This chapter is concerned with the neurogenic factors that influence the evoked potentials of the mammalian cortex. The aim here is to survey some of the neurogenic factors that influence the electrical responses evoked in the neocortical gray matter by a brief volley of afferent impulses. Because of the importance and immediacy of the question, special emphasis has been given to heterosynaptic convergences of specific sensory and unspecific reticular impulses at the thalamic and cortical levels. Like the mono- and polysynaptic reflex responses of spinal moto-neurons to single electrical stimuli, the evoked potentials of the cerebral cortex are obviously the artificial product of experiments devised for analytical purposes. Yet the study of the factors of variation of these integrated cortical responses throws light on the physiological properties of the neuronal networks of the brain. By doing so, it represents an approach to the knowledge of the primary neural events, which, initiating an immensely complicated chain of neurophysiological processes, underlie perceptual integration.
Keywords: neurogenic factors, mammalian cortex, afferent impulses, heterosynaptic convergences, spinal moto-neurons, primary neural events, neurophysiological processes, perceptual integration
