Spatial and non-spatial auditory processing in the lateral intraparietal area

Research Note


We tested the responses of neurons in the lateral parietal area (area LIP) for their sensitivity to the spatial and non-spatial attributes of an auditory stimulus. We found that the firing rates of LIP neurons were modulated by both of these attributes. These data indicate that, while area LIP is involved in spatial processing, non-spatial processing is not restricted to independent channels.
