ABSTRACT
Like K. S. Lashley, the author too became interested in the neural mechanisms of vision and the modality of vision as one of the most prominent and accessible avenues for tracing sensory input and information processing to the higher levels of cognitive functioning. Combining this interest and his experiences with Magoun in relation to the role of the ascending reticular activating system in arousal behaviorally and activation electrocortically, the author sought to find ways to study the neural mechanisms of attention and perception. The serial order of behavior as in speech and language fascinated Lashley and he was always ready and eager to discuss it and the problems it presented in attempting to unravel the mechanisms of the brain. He was widely read and knowledgeable about basic psychological and neurological data and with the mental phenomena associated with various states of consciousness in normal and pathological conditions.
