Stimulus- and Neural-Referred Visual Receptive Field Properties following Hemispherectomy: A Case Study Revisited

posted in: New Paper | 0

What happens to the visual system of the brain if one hemisphere gets removed completely at a late (age 3) developmental stage? In a paper published in the journal “Neural Plasticity”, Hinke Halbertsma and co-authors revisited the visual field maps properties of such a case, i.e. a patient with hemispherectomy. They found subtle changes of the visual field map properties, both when the brain is visually stimulated and when it is at rest. They argue these changes are not a sign of large scale functional reorganisation of the visual system. Instead, these small-scale properties may be the result of adaptive processing and viewing strategies. Want to know more? Find the article here.
