Respiratory failure is the leading cause of death following a cervical spinal cord injury. Having a reproducible, quantifiable, and reliable pre-clinical animal model of respiratory failure induced by a partial cervical injury will help to understand the subsequent respiratory and non-respiratory neuroplasticity and allow testing putative repair strategies.

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. • The brain's ability to change begins with the growth of dendrites and axons, which effectively increases the structural...

Neuronal plasticity is an increasingly recognized, but insufficiently understood feature of the gastrointestinal (GI) tract. Here, in the example of human pancreatic disorders, we present an in vitro neuroplasticity assay for the study of neuronal plasticity in the GI tract at both morphological and functional level.

Source: Suneel Dhand, MD, Attending Physician, Internal Medicine, Beth Israel Deaconess Medical Center Disorders of the respiratory system with a chief complaint of shortness of breath are among the most common reasons for both outpatient and inpatient evaluation. The most obvious visible clue to a respiratory problem will be whether the patient is displaying any signs of respiratory distress, such as fast respiratory rate and/or cyanosis. In a clinical situation, this will always require...
FAQs
Changes in synaptic transmission can alter how strongly respiratory neurons communicate, while changes in excitability affect how readily those neurons respond and generate activity. Together, these mechanisms can modify the operation of brainstem respiratory networks, sensory pathways, and spinal motor circuits. Their combined effects help explain why respiratory muscle activation and breathing patterns may change after altered conditions or neurological injury.
Respiratory neuroplasticity can emerge across interconnected levels rather than within a single breathing center. Brainstem respiratory networks organize core respiratory activity, sensory pathways convey information relevant to breathing, and spinal motor circuits influence respiratory muscle activation. Examining these sites together is important because adaptation at one level may affect signal processing and motor output elsewhere in the respiratory system.
Experience, injury, disease, and altered chemical conditions can all prompt respiratory neuroplastic changes. These influences may modify synaptic transmission or neuronal excitability within respiratory control circuits, producing longer-term adjustments in breathing patterns or muscle activation. Considering the initiating condition helps distinguish an adaptive response that supports respiratory function from a change associated with neurological impairment or respiratory disease.
The consequences depend on how circuit changes affect ventilation and respiratory muscle control. Adaptations may support recovery when neurological damage has weakened breathing-related pathways, but other changes may fail to restore effective function or contribute to impaired ventilation. This distinction makes it important to study not only whether plasticity occurs, but also when its resulting breathing pattern is functionally helpful.
Research can examine how breathing-related adaptations are distributed across brainstem networks, sensory pathways, and spinal motor circuits, especially after spinal cord injury, stroke, neurological disorders, or altered chemical conditions. Investigators can relate changes in circuit function to breathing patterns and respiratory muscle activation. This approach connects cellular or network-level mechanisms with outcomes that matter for respiratory recovery.
These strategies are relevant when respiratory neuroplasticity could be directed toward improved breathing after neurological injury or disease. Respiratory training aims to engage adaptive changes, whereas targeted neuromodulation is identified as another way to influence respiratory circuits. Their significance depends on understanding which neural adaptations improve ventilation and which may be maladaptive, rather than treating every circuit change as beneficial.
