Brain States: Top-Down Influences in Sensory Processing

Mostrar todas las versiones(3)

All cortical and thalamic levels of sensory processing are subject to powerful top-down influences, the shaping of lower-level processes by more complex information. New findings on the diversity of top-down interactions show that cortical areas function as adaptive processors, being subject to atte...
