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.
Brain plasticity — also called neuroplasticity — is an odd term for most people, with the word “plastic” causing images of Tupperware or Saran Wrap to pop into your head.
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 ...
Sensory substitution concerns human perception and the plasticity of the human brain; and therefore, allows us to study these aspects of neuroscience more through neuroimaging. Sensory substitution systems may help people by restoring their ability to perceive certain defective sensory modality by using sensory information from a functioning ...
Activity-dependent plasticity is seen in the primary visual cortex, a region of the brain that processes visual stimuli and is capable of modifying the experienced stimuli based on active sensing and arousal states. It is known that synaptic communication trends between excited and depressed states relative to the light/dark cycle.
Some people may use the right hemisphere for language, and isolated damage of Wernicke's area cortex (sparing white matter and other areas) may not cause severe receptive aphasia. [ 5 ] [ 23 ] Even when patients with Wernicke's area lesions have comprehension deficits, these are usually not restricted to language processing alone.
The phenomenon was first described by Francis Galton in 1880 in a statistical study about mental imagery. [2] Galton wrote: To my astonishment, I found that the great majority of the men of science to whom I first applied, protested that mental imagery was unknown to them, and they looked on me as fanciful and fantastic in supposing that the words "mental imagery" really expressed what I ...
The hippocampus (pl.: hippocampi; via Latin from Greek ἱππόκαμπος, 'seahorse'), also hippocampus proper, is a major component of the brain of humans and many other vertebrates. In the human brain the hippocampus, the dentate gyrus, and the subiculum are the components of the hippocampal formation located in the limbic system.
