The adaptive changes in the patterns of cognition that are related to the brain activity are known as cognitive plasticity. Brain plasticity refers to the changes on a non-neuron level that can be stimulated by experience. Neuroplasticity encompasses the potential of neural networks in the brain to change through growth and reorganization. A few of its examples are changes in the circuit and network resulting from environmental influences, learning a new ability, psychological stress and practice. The changes may range from individual neuron pathways that make new connections, to systematic adjustments like cortical remapping. The degree of plasticity is higher in the developing brain than the adult brain. The various studies that are constantly contributing towards advancing technologies and evolution of this field are examined in detail in this book. Also included herein is a detailed explanation of the various concepts of cognitive and brain plasticity. This book will help the readers in keeping pace with the rapid changes in this field.
