The lateral spinothalamic tract is a pathway in the spinal cord responsible for transmitting sensations of pain and temperature to the brain. Hypofunction refers to a decrease in the normal functioning of this pathway, resulting in reduced or altered perception of pain and temperature.
Lateral spinothalamic tract hypofunction can occur due to various factors such as injury, disease, or compression of the spinal cord. When this pathway is not functioning properly, individuals may experience reduced sensitivity to pain and temperature changes, which can impact their ability to detect and respond to potential threats or injuries.
Types:
There are different types of lateral spinothalamic tract hypofunction, depending on the underlying cause. These may include:
- Traumatic injury to the spinal cord
- Degenerative conditions affecting the spinal cord
