OBJECT RECOGNITION and SPACE AND TIME

Ventral Visual System

Brain system for recognizing objects, extends to temporal lobe.

Inferotemporal Cortex

Ventral stream in monkeys, divided into three parts.

Receptive Field

Region of space a neuron responds to.

Visual Agnosia

Inability to recognize objects despite intact sensory processes.

Apperceptive Agnosia

Impaired perception of basic visual features.

Associative Agnosia

Can process features but not recognize objects.

Prosopagnosia

Inability to recognize faces, despite recognizing other objects.

Dynamic Coding

Objects coded by activity patterns across cell populations.

Viewpoint-Independent Representations

Recognizing objects regardless of size or position.

Featural Recognition

Left hemisphere specializes in recognizing individual features.

Configural Recognition

Right hemisphere specializes in recognizing holistic configurations.

Category Specificity

Certain stimuli processed differently in the brain.

Auditory Agnosia

Impaired recognition of verbal and nonverbal sounds.

Somatosensory Agnosia

Impaired recognition of objects by touch.

Lateral Occipital Complex

Links tactile and visual object representations.

Dorsal Visual System

Processes spatial relations, part of 'where' visual system.

Posterior Parietal Cortex

Responsive to visual information for spatial processing.

Binocular Disparity

Depth perception from comparing inputs from both eyes.

Motion Parallax

Depth perception from object movement across the retina.

Egocentric Reference Frame

Spatial positions coded relative to the self.

Allocentric Reference Frame

Spatial positions coded relative to external references.

Area MT (V5)

Critical for perceiving motion in the visual field.

Akinetopsia

Selective deficit in motion perception.

Optic Ataxia

Disorder affecting visually guided reaching movements.

Intraparietal Sulcus

Region involved in representing numerosity.

Route-Based Navigation

Navigating using specific paths or routes.

Map-Based Navigation

Navigating using a cognitive map of the environment.

Parahippocampal Place Area

Responds to landmarks in spatial navigation.

Retrosplenial Cortex

Represents location in spatial navigation.

Hippocampus

Contains map-like knowledge of familiar environments.
