Prevailing View

A prevailing view considers the self a property of only the most evolutionarily advanced animals. We propose that a “protoself’ is already present in simple life forms and may be an inherent aspect of all living systems. A separation of the “self” from the “outside” world allows organisms to model the external environment and to act on it. The appearance of the nervous system in larger organisms, initially necessary for speed, enabled the generation of more sophisticated models of the environment and the organism that could be harnessed for more accurate predictions of the future. Spontaneous neuronal activity, such as the default mode network which is prevalent in humans, may serve as an integrator of the model, physically implementing the self as an emergent property.

Spontaneous Neuronal Activity

Recent imaging studies have implicated the anterior cingulate cortex (ACC) in various cognitive functions, including attention. However, until now, there was no evidence for changes in neuronal activity of individual ACC neurons during performance of tasks that require attention and effortful thought. We hypothesized these neurons must exist in the human ACC. In this study, we present electrophysiological data from microelectrode single neuron recordings in the human ACC of neuronal modulation during attention-demanding tasks in 19% of 36 neurons tested. These findings provide the first direct evidence of an influence of a cognitive state on the spontaneous neuronal activity of human ACC neurons.
