Steadiness in Stroke & Classifying Spasms

Tuesday morning was one of those blocks of time where I actually had very little going on and only a couple of posters to visit. The posters I did visit brought me from my dissertation question of how the nervous system changes with age to the question of what happens with neurological disorders.



Control of constant low-level isometric force after stroke- #568.20



Dr. McNulty's study was not… Continue

Surface EMG Decomposition & Dynamic Clamping

Decomposition



At 11:30 a.m. I attended a symposium titled "Decomposition of Surface EMG Signals into Constituent Action Potentials". This symposium consisted of an introductory presentation Dr. Carlo J. De Luca covering the physiology of surface EMG and the motor unit action potentials that comprise this signal. Following that the microphone was handed over the Dr. Hamid Nawab who discussed further the technical aspects of the decomposition algorithms that analyze the surface… Continue

Variability in Measures of Hand Movements

Greater amount of visual feedback alters muscle activity and reduces force variability during constant isometric contractions.- 354.1



My Monday morning began with a stroll down the poster aisles, stopping first at the poster of Sim Baweja. The relation between visual feedback and force variability is unknown. Some have suggested that either too much or too little feedback can have a negative impact on force control (U-shaped function). Sim had subjects match a force target on… Continue

Tendon Tap Responses in Stroke Patients.

Heteronymous Ia afferent connections in the upper limb following stroke- 271.4



My favorite poster of the Sunday afternoon session was discovered by pure chance. I was walking through the Theme D posters when the first word of the poster title "Heteronymous" caught my eye. Although I've done some work on heteronymous reflex modulation in healthy adults, I never knew what happened to these pathways with stroke. Thanks to Gwyn Lewis, I have a better idea : )



Gwyn's… Continue

Fatigue in Neck Muscles & Trapezius Activity During Rest

The velocity recovery function in sternocleidomastoid muscle fibers and its dependence on fatigue- 179.22



My poster presentation was during Sunday morning's session. I don't typically stray very far from my own poser during the time it is up but I was able to review the work of a few posters in my area. Immediately next to me was a poster by Dr. Deborah Falla. Dr. Falla sought to investigate how muscle fatigue would alter the velocity recovery function of sternocleidomastoid… Continue

Becoming Batman and Backyard Brains

Saturday afternoon was the official start of the poster presentations and a reminder of how massive this conference is.



Backyard brains: You too can do neurophysiology in your garage- # 20.1



"What would you say if I told you that you could record neuronal spikes for under $100?" As soon as I heard this I knew I was in the presence of Tim Marzullo, co-founder of Backyard Brains. Last year was… Continue

Magic, the Brain, and the Mind



Well I got to the convention center this morning to discovered why I have nothing in my itinerary planner for this morning, nothing is happening yet!



I am set up in the special lecture area waiting for the Dialogues Between Neuroscience and Society to begin at 11 am.



My favorite twitter comment on this event is "I wonder if there will be an interlude of magic by Penn and Teller"!



A report is soon to follow :… Continue

SfN 2.0

Wow. I am amazed at the torrent of information about SfN on twitter at the moment. Not quite a "trending topic" (such as #ballonboy, happening just up the highway from Boulder), but definitely some new tweets to read after every refresh.



This made me realize that SfN has clearly entered a "2.0 stage". By this I mean that neuroscientists are now… Continue
