Tyler Henderson

Tyler Henderson is a Lecturer in Exercise & Sport Science at the Faculty of Health. His research focuses on the neurophysiological mechanisms underlying human motor control, particularly the role of serotonin in modulating spinal and cortical motoneuron excitability, muscle fatigue, and tremor. He is actively contributing to the fields of neuroscience and exercise physiology through empirical and review publications.

Research Interests: Dr. Henderson's work centers on serotonin signaling in the central nervous system and its impact on motor performance. Key areas include 5-HT2 receptor function, neuromodulation of spinal motoneurons, and the influence of pharmacological agents like paroxetine on muscle activation and fatigue. His studies integrate neurophysiological techniques such as transcranial magnetic stimulation and electromyography with pharmacological interventions.

The recent publications (2022–2024) reveal a consistent focus on serotonergic and noradrenergic systems in motor control. These works span topics from cortical and spinal excitability to muscle fatigue and tremor suppression, indicating a multidisciplinary approach combining neuroscience, pharmacology, and exercise science. The research often involves human subjects and employs both experimental and review methodologies.

Scientific Contributions:

• Investigated serotonin’s role in limiting muscle activation during high-intensity fatigue.
• Explored how increased serotonin availability improves force steadiness and suppresses tremor.
• Analyzed the necessity of excitatory drive for serotonin to modulate motoneuron excitability.
• Reviewed monoaminergic contributions to motor cortical and spinal excitability.

Dr. Henderson collaborates with researchers such as J. L. Taylor, J. R. Thorstensen, S. Morrison, M. G. Tucker, and J. J. Kavanagh. His work is supported by robust neurophysiological data and has been published in peer-reviewed journals including European Journal of Neuroscience, Neuropharmacology, and Journal of Neurophysiology. While no formal advising or grant information is listed, his active publication record suggests ongoing research activity in neuro-motor physiology.

Laboratory and Research Environment: Though specific lab names are not mentioned, his research fingerprint indicates deep engagement with neurophysiological testing and pharmacological modulation in human motor systems, likely conducted within a university-based exercise neuroscience or neurophysiology laboratory.
