Multiple cortical representation of muscles controlling hand/fingers, represents the functional frame for the extraordinary repertoire of movement strategies (i.e. concerted actions orchestrated by many –sometimes the same- muscles acting on different joints at different times [24], [37], [47]).
Convergence, divergence, multiple muscle cortical representations and the influence of posture seem to play a pivotal role also in humans, orchestrating several muscles 'in concert' during motor actions, motor learning and post-lesional 'plastic' brain reorganization [29] [32].
These observations argue for an initial near-simultaneous representation of a tactile stimulus in multiple cortical layers rather than for a sequential representation radiating from the granular layer.
The cortical representations of muscles overlap broadly (e.g. [23], [24]), and dense connectivity exists between multiple frontal motor areas [25].
Spontaneously emerging cortical representations of visual attributes.
Details on the mathematical formulation of the auditory cortical representations can be found in [34, 35].
The collection of tools is designed to require minimal user interaction to produce cortical representations.
To achieve rapid imaging of high-resolution dynamics of cortical representations of spontaneous and evoked activity, we designed a novel data acquisition protocol for sensory stimulation by rapidly interleaving multiple stimuli in continuous sessions of optical imaging with voltage-sensitive dyes.
ATB was also estimated for regions of interest (ROIs) of multiple cortical regions.
The auditory cortical representations [34, 35], the mel-frequency cepstral coefficients [36], and the chroma features [37] were used for music representation.
