Shivering is mediated via the predominantly uncrossed reticulospinal tract. We report a case of a patient with left lateral medullary tract infarct involving the reticulospinal tract who displayed ipsilateral absence of shivering during a febrile episode. The physiology and anatomy of shivering and the reticulospinal tract is reviewed.

There is a consensus that motor recovery post-stroke primarily depends on the degree of the initial connectivity of the ipsilesional corticospinal tract (CST). Indeed, if the residual CST connectivity is sufficient to convey motor commands, the neuromotor system continues to use the CST predominantly, and motor function recovers up to 80%. In contrast, if the residual CST connectivity is insufficient, hand/arm dexterity barely recovers, even as the phases of stroke progress.

A decline in upper limb strength is common with normal aging. However, whether age-related strength decline is paralleled by reduced excitability of descending motor pathways is unclear. The reticulospinal tract is a key subcortical pathway involved in gross motor output and exhibits increased excitability following resistance training.

Foundational neuroscience is crucial to locating lesions, understanding current functional limitations, making correct prognoses, and designing holistic and realistic treatment plans for stroke patients. A model bridging neuroscience knowledge and clinical practice was assessed through a rare pontine infarction case. A 76-year-old patient suffered two consecutive right-sided pontine ischemic strokes, leading to significant motor and sensory abnormalities on the left side.

Background: Dynamic spasticity (DS) is a common complication post-spinal cord injury (SCI), marked by intermittent increases in muscle tone during postural transitions or movement. Despite its prevalence, high-quality research on DS incidence, risk factors, and underlying mechanisms in SCI patients remains limited. With the growing application of spinal cord stimulation (SCS) for spasticity control, the role of proprioception in DS development has garnered attention.

Finger dexterity, and finger individuation in particular, is crucial for human movement, and disruptions due to brain injury can significantly impact quality of life. Understanding the neurological mechanisms responsible for recovery is vital for effective neurorehabilitation. This study explores the role of two key pathways in finger individuation: the corticospinal (CS) tract from the primary motor cortex and premotor areas, and the subcortical reticulospinal (RS) tract from the brainstem.
