"Whatever information the brain is fed, it will learn to adjust to it and extract what it can. As long as the data have a structure that reflects something important about the outside world, the brain will figure out how to decode it. There’s an interesting consequence to this: your brain doesn’t know, and it doesn’t care, where the data come from....
.....Whatever information comes in, it just works out how to leverage it. This makes the brain a very efficient kind of machine. It is a general-purpose computing device. It just sucks up the available signals and determines - nearly optimally - what it can do with them.[1]” writes David Eagleman, a renowned neuroscientist best known for his research on time perception, synesthesia, and the neural basis of sensory substitution and time perception.
Eagleman acknowledges that the brain's plasticity allows it to modify its responses to new types of stimuli. Information carried by the reflection of electromagnetic radiation is captured by the photoreceptors in the eyes. Air compression waves are detected by the auditory receptors in the ears. Heat and texture information are sensed by the extensive network of sensory receptors in the skin.
Chemical signals are detected by the olfactory receptors in the nose and the taste receptors on the tongue. All this sensory information is translated into neural signals, creating a dynamic map of the external world within the brain's vault.
In the realm of neuroscience, the term "neuroplasticity" is employed to describe the brain's ability to continuously reshape and reorganize itself throughout a person's life. The brain is a dynamic, ever-evolving organ that continually adapts to new experiences and information. It is not molded once and then frozen in that mold permanently.
The dynamic nature of this evolution[2] allows it to adapt to the flux and changing environment around it. Eagleman uses the term “livewiring” to better describe the brain's ongoing adaptability and its seamless integration of what might traditionally be considered hardware and software, as well as for us to appreciate it as a living, adaptable system that is constantly seeking and processing information.
The Concept of Neuroplasticity
How then should we think of neuroplasticity and apply this into our lives?
First, neuroplasticity is not a one-time event but a continuous process that occurs throughout our lives. The brain remains adaptable and capable of change from childhood through adulthood and even into old age. This adaptability underlies learning, memory, and the ability to acquire new skills.
Second, neuroplasticity involves several mechanisms, including:
Synaptic Plasticity: Changes in the strength of connections between neurons (synapses).
Structural Plasticity: Changes in the physical structure of the brain, such as the growth of new neurons (neurogenesis) and the formation of new synaptic connections.
Functional Plasticity: The brain's ability to shift functions from damaged areas to undamaged areas after injury.
Third, various factors influence neuroplasticity, including:
Experience and Learning: Engaging in new activities, learning new skills, and challenging the brain with novel tasks enhance neuroplasticity.
Physical Exercise: Regular physical activity has been shown to promote neurogenesis and improve cognitive function.
Environment: A stimulating environment with diverse sensory inputs can enhance brain plasticity.
Social Interaction: Positive social interactions and supportive relationships contribute to brain health and adaptability.
Putting Neuroplasticity into Action
1. Learning and Memory: When we learn something new, such as a language or a musical instrument, our brain creates and strengthens neural pathways associated with these skills. Over time, these pathways become more efficient, leading to improved proficiency.
2. Recovery from Injury: After a brain injury, such as a stroke, neuroplasticity enables the brain to reorganize itself. Functions that were once performed by damaged areas can be taken over by other parts of the brain, allowing for partial or full recovery of abilities.
3. Sensory Substitution: In individuals who are blind or deaf, neuroplasticity allows the brain to repurpose areas typically used for vision or hearing to process information from other senses, such as touch or smell. This adaptation enhances the individual's ability to navigate and interact with their environment.
By understanding the brain as "livewired," we acknowledge its incredible capacity for change and resilience. This perspective not only enhances our appreciation of the brain's capabilities but also inspires us to engage in activities that promote brain health and plasticity throughout our lives.
