Affective blindsight

Electrophysiological correlates of affective blindsight

An EEG investigation was carried out in a patient with complete cortical blindness who presented affective blindsight, i.e. who performed above chance when asked to guess the emotional expressions on a series of faces. To uncover the electrophysiological mechanisms involved in this phenomenon we combined multivariate pattern recognition (MPR) with local field potential estimates provided by ele...

From affective blindsight to emotional consciousness.

Following destruction or denervation of the primary visual cortex (V1) cortical blindness ensues. Affective blindsight refers to the uncanny ability of such patients to respond correctly, or above chance level, to visual emotional expressions presented to their blind fields. Fifteen years after its original discovery, affective blindsight still fascinates neuroscientists and philosophers alike,...

From affective blindsight to affective blindness: When cortical processing suppresses subcortical information

Blindsight

important for screening purposes, but have to be combined with detailed biochemical and functional studies. In fact, the experience with yeast showed that the many possibilities offered by genomics and proteomics shifted the emphasis from cloning back to biochemistry and thus gave us more time for functional studies. What is the biggest hindrance to science? Administrators who like paragraphs m...

Facial blindsight

Blindsight denotes unconscious residual visual capacities in the context of an inability to consciously recollect or identify visual information. It has been described for color and shape discrimination, movement or facial emotion recognition. The present study investigates a patient suffering from cortical blindness whilst maintaining select residual abilities in face detection. Our patient pr...
