Summary
Lifelong focused attention to touch preserves tactile acuity in old age. This study found that experienced pianists, like blind individuals, maintained high tactile acuity, suggesting practice, not blindness, is key.
Area of Science:
- Neuroscience
- Sensory Perception
- Human Aging
Background:
- Previous research indicated blind individuals retain high tactile acuity throughout life, unlike sighted individuals.
- Age-related decline in tactile acuity is typical for sighted populations.
Purpose of the Study:
- To investigate if lifelong focused attention to touch, rather than blindness itself, preserves tactile acuity in old age.
- To test the hypothesis that extensive tactile practice, as seen in musicians, maintains acuity in older adults.
Main Methods:
- Assessed tactile acuity in young and old sighted pianists using Landolt ring and dot pattern charts.
- Compared pianist performance to previously published data from blind and sighted individuals.
Main Results:
- Young and old pianists showed no significant difference in tactile acuity on the ring chart.
- Pianists performed similarly to blind subjects on the ring chart, outperforming sighted subjects from a prior study.
- Pianists exhibited an age-related decline in tactile acuity on the dot chart, but less severe than sighted individuals.
Conclusions:
- Lifelong focused attention to touch appears to preserve tactile acuity into old age.
- The findings support the hypothesis that dedicated sensory practice can counteract age-related sensory decline.

Tactile and Chemical Senses
727
Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex.

Communication
8.7K
Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction.

What is Conservation Biology?
24.0K
Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials.

Sustainable Development
14.8K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Keystone Species
24.2K
Measures of species biodiversity, such as richness (i.e., the number of species present) and evenness (i.e., their relative abundance), describe an ecological community’s structure. Many factors affect community structure, including abiotic factors (e.g., sunlight and nutrients), disturbances (e.g., fire or flood), species interactions (e.g., predation or competition), and chance events (e.g., foreign species invasion). Certain species—such as keystone species—also play a...

The Fossil Record
27.1K
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...
