State-dependent Computations: Spatiotemporal Processing in Cortical
D. Buonomano and W. Maass
A conspicuous ability of the brain is to seamlessly assimilate and process
spatial and temporal features of sensory stimuli. This ability is
indispensable for the recognition of natural stimuli. Yet, a general
computational framework for processing spatiotemporal stimuli remains
elusive. Recent theoretical and experimental work suggests that
spatiotemporal processing emerges from the interaction between incoming
stimuli and the internal dynamic state of neural networks which includes not
only ongoing spiking activity, but also 'hidden' neuronal states such as
short-term synaptic plasticity.
