Abstract:
Action integration is the process through which actions performed on a stimulus and perceptual aspects of the stimulus become bound as a unitary object. This process appears to be controlled by the dopaminergic system in the prefrontal cortex, an area that is known to decrease in volume and dopamine functioning in older adults. Although the decline should lead to reduced action integration in older adults, we found equivalent integration in both young and older adults. This indicates that older adults may be able to compensate for their dopaminergic deficiencies by activating additional neural networks that are not used by young adults.

Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Somatic Spinal Reflexes
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...
