Unconscious networking
Article Abstract:
Functional magnetic resonance imaging (fMRI) is used to examine the spontaneous fluctuations of neural activity in the monkey brain during anesthesia. The network has extended beyond those expected simply from connection between signal synapses and this approach has helped in revealing similarities between brain regions in different species, especially when combined with task-induced brain activations that are related to sensory or cognitive functions.

Coding of intention in the posterior parietal cortex
Article Abstract:
The posterior parietal cortex which is located between the motor cortex and the areas of the brain that process visual and spatial information seems to be well placed for performing the function of transforming a sensory signal into motor output. This area contains signals representing visual stimuli that are routed into specific motor channels depending on the job in hand or signals related to motor intention.

Intrinsic functional architecture in the anaesthetized monkey brain
Article Abstract:
Whole-brain blood-oxygen-level-dependent (BOLD) functional magnetic resonance imaging (fMRI) is used in isoflurane-anaesthetized monkeys even at anaesthetic levels known to induce profound loss of consciousness. The results have shown that coherent system fluctuations have reflected an evolutionarily conserved aspect of brain functional organization that transcends levels of consciousness.
