The present chapter integrates neural networks’ connectivity into a model that explores consciousness and volitional behavior from a neurofunctional perspective. The model poses a theoretical evidenced-based framework that organizes the brain journey of neural information flow from the ascending reticular activating system and non-specific thalamic nuclei, to cortical networks, such as the...

The Prefrontal Cortex (PFC) is one of the principal brain regions studied in consciousness. Previous investigations suggest that the PFC is an important neural hub in both awareness and the manipulation of the content of consciousness. Despite a consensus in the scientific community regarding PFC function in cortico-cortical networks, there is still intense debate as to its role in the...

The thalamo-cortical system has been defined as a neural network associated with consciousness. While there seems to be wide agreement that the thalamo-cortical system directly intervenes in vigilance and arousal, a divergence of opinion persists regarding its intervention in the control of other cognitive processes necessary for consciousness. In the present manuscript, we provide a review of...
