This graph took me 3 years to make. It's perhaps the largest-ever #metaanalysis of #TMS #BrainStim data. It includes my first real scientific discovery 🧵: When you stimulate the hand with a brief electric pulse, your brain and spinal cord are momentarily less excitable: muscle output decreases 1/n
Muscle excitability (y-axis) plot against the time between stimulation of the hand (PNS) and stimulation of the cortico-spinal pathway (TMS) to the muscle (x-axis). The x-axis is in milliseconds, from 1 to 1000 on a log scale; the y-axis is the log10 ratio of muscle excitability with prior hand stimulation versus without. Each blue dot in the figure is a group mean, obtained from 353 papers. The blue line is the random effect meta-analytic mean; where the blue line goes thicker (between 17-64ms, then 100-320ms) there is a significant meta-analytic effect (i.e., the line is below zero, muscle excitability is decreased). The plot includes over 11000 datapoints. Most datapoints are concentrated in the 16-30ms period, which is studied as 'short-latency afferent inhibition' (SAI).

Scientists just settled a decades-old debate about the brain’s mirror neurons
A new study reveals that mirror neurons don’t just care about final goals. Instead, these brain cells work together in dynamic networks to continuously track the specific physical details of observed movements in real time.

Natural behavior unfolds as a continuous stream of actions. Because these actions often occur in rapid succession, the brain must prepare multiple future actions while the current action is being executed. Our TICS piece explores how this works. www.sciencedirect.com/science/arti...
