Validating Computational Cognitive Process Models across Multiple Timescales

Model comparison is vital to evaluating progress in the fields of artificial general intelligence (AGI) and cognitive architecture. As they mature, AGI and cognitive architectures will become increasingly capable of providing a single model that completes a multitude of tasks, some of which the model was not specifically engineered to perform. These models will be expected to operate for extend...

Distinct roles for GABA across multiple timescales in mammalian circadian timekeeping.

The suprachiasmatic nuclei (SCN), the central circadian pacemakers in mammals, comprise a multiscale neuronal system that times daily events. We use recent advances in graphics processing unit computing to generate a multiscale model for the SCN that resolves cellular electrical activity down to the timescale of individual action potentials and the intracellular molecular events that generate c...

Are the Primary Sensory Cortices Multisensory?

Historically the brain has been viewed as operating in a modular and hierarchical manner. In particular it was previously assumed that each of the primary sensory cortices processed input from a single sensory modality before feeding this information to higher regions of the brain devoted to multisensory integration. This review however outlines a wealth of findings that have emerged in recent ...

Functional selectivity in sensory-deprived cortices.

In a recent study, Lomber, Meredith, and Kral (2010) investigated crossmodal reorganization in congenitally deaf cats. They demonstrated that specific regions of the auditory cortex are responsible for distinct supranormal visual performances following early auditory deprivation. These exciting results are considered in light of recently increasing research suggesting that crossmodal plasticity...
