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.
How the brain changes. Brain plasticity science is the study of a physical process. Gray matter can actually shrink or thicken; neural connections can be forged and refined or weakened and severed.
Attention is a broad construct that refers to "the cognitive ability that allows us to deal with the inherent processing limitations of the human brain by selecting information for further processing". [55] Since the human brain has limited resources, people use their attention to zone in on specific stimuli and block out others. [citation needed]
Dr. Chapman is the co-leader of the BrainHealth Project at the Center for Brain Health, a scientific study to measure people’s ability to affect their brain fitness. She explains that there are ...
The brain plays a big part in the aging process, and scientists think they’ve pinpointed the specific cells that control it.. In a study of mice, researchers at the Allen Institute identified ...
While plasticity is evident throughout the human lifespan, it occurs most often at younger ages, during sensitive periods of development. [6] This is a function of synaptic pruning , a mechanism of plasticity where the overall number of neurons and neural pathways are reduced, leaving only the most commonly used—and most efficient—neural ...
Plasticity in the brain affects the strength of neural connections and pathways. Nonsynaptic plasticity is a form of neuroplasticity that involves modification of ion channel function in the axon, dendrites, and cell body that results in specific changes in the integration of excitatory postsynaptic potentials and inhibitory postsynaptic potentials.
Nearly 40% of adults over the age of 65 say they’ve noticed some cognitive decline. But that doesn’t mean it’s all downhill. In many ways, you can maintain your brain health and function as ...
