Abstract:

There is general consensus that local representations are modulated by information that is relayed in a bottom-up and/or top-down fashion. Bottom-up and top-down modulations have traditionally been thought of situations in which local computations are determined by information that is either at a lower level of representation (e.g., sensory-motor representations are at a lower level of representation when compared to object-specific shape) or at a higher-level of representation (e.g., either attentional moduçations, or object processing being modulated by context or intentions). This leaves space for modulations on local computations that are dependent on information that is at the same level of representation (e.g., Object-related grasping information and object-related surface information) – what I call Horizontal Modulations.
In this talk I will show how distal processing seems to influence local computations within category-specific networks by looking at correlation (such as functional connectivity) as well as more causal neuroscientific evidence (e.g., neuromodulation and patient work).
