Summary
The mammalian brain cortex is not static; its maps can change throughout life. This neuroplasticity, observed in sensory and motor maps, offers insights into brain network function.
Area of Science:
- Neuroscience
- Neurobiology
- Brain Plasticity
Background:
- Historically, central nervous system wiring and cortical maps were considered static.
- Recent research challenges this view, revealing dynamic changes in brain organization.
Purpose of the Study:
- To explore the dynamic nature of cortical maps in the mammalian brain.
- To understand the implications of brain plasticity for neural network function.
Main Methods:
- Studies on specific animal genetic strains.
- Analysis of animals with varied perinatal and adult histories.
- Investigation of lesion effects and perceptual learning on cortical representations.
Main Results:
- Cortical map organization is modifiable from conception to death.
- Peripheral and central lesions significantly impact sensory and motor cortical representations.
- Perceptual learning demonstrates the brain's capacity for reorganization.
Conclusions:
- The adult brain possesses significant organizational capacity.
- Cortical map changes serve as models for understanding lifelong alterations in complex brain networks.

01:01Neuroplasticity
Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.
00:58Plasticity
Plasticity is the property where an object loses its elasticity and undergoes irreversible deformation, even after the deformation forces are eliminated. If a material deforms irreversibly without increasing stress or load, then this is called ideal plasticity. For example, when a force is applied to an aluminum rod, it changes its shape, but it does not return to its original shape once the force is removed. Plastic deformation or ductility is thus a permanent deformation or change in the...
01:23Somatosensory, Motor, and Association Cortex
The somatosensory cortex in the parietal lobes is crucial for interpreting sensory data such as touch, temperature, and proprioception. The somatosensory cortex, situated in the parietal lobes, plays a vital role in interpreting sensory information like touch, temperature, and proprioception—awareness of body position. This specialized brain region features an organized structure wherein neurons at the top primarily process sensations originating from the lower body. In contrast, those at the...
01:33Somatosensation
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.
