The article presents a study about parietal cortex that considerably encodes the category or meaning of familiar visual images, as conducted by investigators from Harvard Medical School (HMS). According to the research, with David Freedman being the study's lead author and an HMS postdoctoral research fellow in neurobiology, the parietal cortex is an area of the brain where memories and categorization of things take place. As asserted, the categories are encoded by the activity of individual neurons and then proceeded to the parietal cortex which learns and recognizes the meaning of the things being observed. Considering the results, Freedman is optimistic this type of research will eventually contribute to a better understanding of neurological diseases and disorders.

    Optic ataxia is a disorder associated with posterior parietal lobe lesions, in which visually guided reaching errors typically occur for peripheral targets. It has been assumed that these errors are related to a faulty sensorimotor transformation of inputs from the 'ataxic visual field'....

    Searching for and recognising objects in complex natural scenes is implemented by multiple saccades until the eyes reach within the reduced receptive field sizes of inferior temporal cortex (IT) neurons. We analyse and model how the dorsal and ventral visual streams both contribute to this....

We found that the firing rates of LIP neurons were modulated by both of these attributes. These data indicate that, while area LIP...
