By Georg Northoff

Neuroscience has made significant development in knowing how the mind works. we all know a lot in regards to the molecular-genetic and biochemical underpinnings of sensory and motor services. contemporary neuroimaging paintings has opened the door to investigating the neural underpinnings of higher-order cognitive features, corresponding to reminiscence, cognizance, or even loose will. In these kinds of investigations, researchers observe particular stimuli to urge neural task within the mind and search for the functionality in query. despite the fact that, there's extra to the mind and its neuronal states than the adjustments in job we result in via utilizing specific exterior stimuli.

In quantity 2 of Unlocking the mind, Georg Northoff addresses awareness by means of hypothesizing in regards to the courting among specific neuronal mechanisms and a few of the out of the ordinary positive factors of recognition. Northoff places awareness within the context of the resting nation of the mind thereby offering a brand new perspective to the controversy that allows very fascinating insights into the character of awareness. furthermore, he describes and discusses distinct findings from assorted branches of neuroscience together with unmarried telephone information, animal info, human imaging facts, and psychiatric findings. This yields a special and novel photograph of the mind, and may have a tremendous and lasting effect on neuroscientists operating in neuroscience, psychiatry, and comparable fields.

Example text

The encoding of neural activity across different discrete points in physical time and space makes possible the constitution of a spatiotemporal structure. ” This is because the spatiotemporal structure is based on the encoding of temporal and spatial differences between different stimuli rather than on the stimuli themselves and their respective physical features. INTRODUCTION I: THE BRAIN AND ITS INTRINSIC FEATURES The spatiotemporal structure is based on the encoding of the statistical frequency distribution of the stimuli across different discrete points in physical time and space, that is, the natural statistics of the encoded stimuli.

These intrinsic features must be distinguished from the brain’s extrinsic features, like the various functions and their related contents the brain processes in its neural activity that underlies its sensory, motor, affective, and cognitive functions. The CHC postulates that the brain’s intrinsic features themselves predispose, and thus make necessary or unavoidable, the generation of consciousness. If the brain were characterized by different intrinsic features, a different encoding strategy, and/or an intrinsic activity without a spatiotemporal structure, consciousness would be altogether impossible.

The introduction of brain imaging extended such faculty psychology to the brain and its different regions and networks. The different psychological faculties were assumed to be related to separate and distinct regions and networks in the brain. xliii INTRODUCTION I: THE BRAIN AND ITS INTRINSIC FEATURES xliv That, however, turned out to be problematic, as the different functions or faculties show extensive overlapping in their respectively recruited regions and neural networks (see Chapters 4–5 as well as Bar et al.
