Visual Processing: Objects & Space Bio 8

These flashcards cover key concepts and definitions related to visual processing, including the dorsal and ventral streams, types of agnosia, and specific brain regions involved in visual recognition.

Ventral Stream

The visual pathway responsible for perceiving and recognizing objects using vision.

Dorsal Stream

The visual pathway responsible for locating and interacting with objects in space using vision.

Prosopagnosia

A neurological condition characterized by the inability to recognize faces, despite the ability to describe facial features.

Agnosia

A condition characterized by a lack of knowing or recognition, which can be specific to different sensory modalities.

Apperceptive Agnosia

A disorder in which the individual has intact low-level perception but cannot perceive the global structure of visual objects.

Associative Agnosia

The inability to recognize objects despite being able to copy them accurately; action-based knowledge is retained.

Hemispatial Neglect

A failure to attend to one side of the visual field, often not caused by a loss of vision.

Calcarine Sulcus

A region in the medial occipital cortex where cortical processing of visual information begins.

Fusiform Face Area (FFA)

A specialized area in the brain, located in the fusiform gyrus, that is involved in face perception.

Optic Ataxia

A disorder resulting from damage to the dorsal pathway, characterized by problems using vision to reach and grasp objects.
