Activity-dependent plasticity is a form of functional and structural neuroplasticity that arises from the use of cognitive functions and personal experience. [ 1 ] Hence, it is the biological basis for learning and the formation of new memories .
Neuroplasticity, also known as neural plasticity or just plasticity, is the ability of neural networks in the brain to change through growth and reorganization. Neuroplasticity refers to the brain's ability to reorganize and rewire its neural connections, enabling it to adapt and function in ways that differ from its prior state.
Neuroplasticity is the process by which neurons adapt to a disturbance over time, and most often occurs in response to repeated exposure to stimuli. [27] Aerobic exercise increases the production of neurotrophic factors [note 1] (e.g., BDNF, IGF-1, VEGF) which mediate improvements in cognitive functions and various forms of memory by promoting blood vessel formation in the brain, adult ...
A focal lesion causes damage that also disturbs the structural and functional connectivity to the brain areas distal to the lesion. The primary mechanism of diaschisis is functional deafferentation, [7] which is the loss of the input of information from the part of the brain that is now damaged. The decrease in information and neural firing to ...
In neuroscience, synaptic plasticity is the ability of synapses to strengthen or weaken over time, in response to increases or decreases in their activity. [1] Since memories are postulated to be represented by vastly interconnected neural circuits in the brain , synaptic plasticity is one of the important neurochemical foundations of learning ...
Tim H. Murphy describes it as, "Stroke recovery mechanisms are based on structural and functional changes in brain circuits that have a close functional relationship to those circuits affected by stroke." [12] Neuroplasticity after a stroke is enabled by new structural and functional circuits that are formed through cortical remapping. A stroke ...
In neuroscience, homeostatic plasticity refers to the capacity of neurons to regulate their own excitability relative to network activity. The term homeostatic plasticity derives from two opposing concepts: 'homeostatic' (a product of the Greek words for 'same' and 'state' or 'condition') and plasticity (or 'change'), thus homeostatic plasticity means "staying the same through change".
The LORETA method can be used in combination with MRI to merge structural and functional activities. It is able to provide even better temporal resolution than PET or fMRI. For the application with live neurofeedback, however, 19-channel neurofeedback and LORETA has limited scientific evidence, and until now, shows no benefit over traditional 1 ...
