Great thread & a must-read for anyone doing #neurostimulation research

hello #brainstim folk. If you aim to stimulate #somatosensory cortex, please ignore the '2cm rule' for finding #S1-hand. This heuristic appears in the majority of #TMS papers. We know this heuristic is wrong (papers below), for example (red=M1-hand, blue=S1-hand) 1/6:

Info from #somatosensory nerves can be actively modified at the #DorsalRootGanglion. This study reveals the existence of tonic & dynamic #GABAergic filtering of action potentials traveling through the #DRG; implications for #PainRelief #PLOSBiology https://plos.io/3VSJFNo

This work talks about the diversity in assessing #somatosensory #impairments in #stroke survivors. Rehab #tech may provide unifying force for objective measures in #clinical practice, but #barriers of adoption are still present. Well this is from the Asian context!

Just published #openaccess in the last week. Our study looking response time data in retired contact sport athletes with a history of repetitive head trauma and #concussions completing cognitive and somatosensory testing. We found no differences in outcomes (i.e., accuracy and/or errors) but we did see a significant difference in response times. The takeaway? Similar to previous studies, retired contact sport athletes can complete basic cognitive testing as accurately as aged-matched controls, but they take longer to respond. The analogy in explaining to these individuals, their families, and the wider lay public at seminars, is like driving a car with the breaks on. #openscience #science #concussioninsport #research #neuroscience #transcanialmagneticstimulation #tms #Somatosensory #neurophysiology

Towards a #Somatosensory #Theory of #Speech #Perception

https://journals.physiology.org/doi/abs/10.1152/jn.00381.2022

Argues the somatosensory system is contributor to speech perception.
1. Evidence for motor contribution to speech perception equally could be somatosensory involvement.
2. Neuroanatomical evidence shows there’s a neural infrastructure that supports somatosensory involvement in auditory processing.
3. Tactile stimulation modifies speech perception & auditory input elicits activity in somatosensory areas.
