receptive field

the spatially discrete region and the features associated with it that can be stimulated to cause the maximal response of a sensory cell. In vision, for example, the receptive field of a retinal ganglion cell is the area on the retina (containing a particular number of photoreceptors) that evokes a neural response. An auditory neuron has a receptive field that can be described either by the range of tones to which it responds or by the receptors that cause this response. Also called receptor field.

integrative agnosia

a form of visual agnosia in which individuals are able to perceive the elements of an object but find it difficult to combine them into a perceptual whole. Typically, symptoms of both apperceptive and associative agnosia are present. Individuals affected by this kind of agnosia can usually draw an object accurately but only through a laborious process.
