Plasticity in the Somatosensory System of Developing and Mature Mammals - The Effects of Injury to the Central and Peripheral Nervous System (eBook, PDF)

• Format: PDF

Produktbeschreibung

Rarely have the many mechanisms that might underlie neural plasticity been examined as explicitly as they are in this broad, lavishly illustrated treatment of plasticity in the somatosensory system. The reader is provided with state-of-the-art knowledge of connections at all levels of the somatosensory system. The authors examine the propensity for changes of connectivity in both the mature and developing mammal and make clear proposals regarding the mechanisms underlying these changes. Their functional significance to relevant psychophysical and neurological observations is also discussed.
