Improvement in Hemodynamic Responses to Metaboreflex Activation after One Year of Training in Spinal Cord Injured Humans [PDF]

, 2014
Spinal cord injured (SCI) individuals show an altered hemodynamic response to metaboreflex activation due to a reduced capacity to vasoconstrict the venous and arterial vessels below the level of the lesion.

Dexmedetomidine – Commonly Used in Functional Imaging Studies – Increases Susceptibility to Seizures in Rats But Not in Wild Type Mice

Frontiers in Neuroscience, 2020
Functional MRI (fMRI) utilizes changes in metabolic and hemodynamic signals to indirectly infer the underlying local changes in neuronal activity. To investigate the mechanisms of fMRI responses, spontaneous fluctuations, and functional connectivity in ...
