Top-down and bottom-up modulation in processing bimodal face/voice stimuli

Event-Related Potentials of Bottom-Up and Top-Down Processing of Emotional Faces

Introduction: Emotional stimulus is processed automatically in a bottom-up way or can be processed voluntarily in a top-down way. Imaging studies have indicated that bottom-up and top-down processing are mediated through different neural systems. However, temporal differentiation of top-down versus bottom-up processing of facial emotional expressions has remained to be clarified. The present st...

Integrating Bottom-up and Top-down Processing in Active Dendrites

| The classical view of information processing in the cortex is that of a bottom-up process in a feed-forward hierarchy. However there is psychophysical, anatomical and physiological evidence that top-down eeects play a crucial role in the processing of input stimuli. Hardly anything is known about the neural mechanisms underlying these effects. Here we investigate a physiologically inspired mo...

Top-down and bottom-up modulation of pain-induced oscillations

Attention is an important factor that is able to strongly modulate the experience of pain. In order to differentiate cortical mechanisms underlying subject-driven (i.e., top-down) and stimulus-driven (bottom-up) modes of attentional pain modulation, we recorded electric brain activity in healthy volunteers during painful laser stimulation while spatial attention and stimulus intensity were syst...

The effect of bottom-up and top-down auditory program training on the development of children's auditory processing skills

Although there have been several previous investigations on the role of auditory training for the development of auditory processing skills, it still remains unknown whether children with auditory processing difficulties can get improved auditory skills after exposure to a multi-modal training experience comprising both visual and tactile stimuli. The present study, therefore, attempted to use ...
