PREPARATORY ATTENTION IN VISUAL CORTEX
INTRODUCTION: Top-down attention makes attentional template that preactivates the visual cortex. Both spatial and content-based attention.
Differences: spatial attention and motor planning
Preparatory attention influence stimulus discrimination and identification
Content-base and irrelevant distractors goal-related
Increasing of baseline firing rates of visual cortex neurons
Indipendence from type of response
Especially for neurons that distinguishes from distractors
Influence speed and accuracy
How explain this effect?
NO automatic priming
YES voluntary activity
Guided Search Model
Mechanisms for discrimination stimulus/distractors
Future directions of this study
Source of preparatory attention?
Frontal parietal cortices / PFC
When do we observe preparatory attention?
Influence of motivational state
How does it work in the real world?
Simplified stimuli vs dynamic enviroment
Across visual hierarchy
Low-level and high-level
Experience role
Expectation - knowledge of probability / Attention - relevance of a stimulus
