intro/background

Question 1

what is TMS

Answer 1

• non-invasive form of brain stimulation
• stimulating at the motor cortex
• momentarily depolarizes the NS creating a muscle twitch

Question 2

what is SAI

Answer 2

• we used TMS to measure short afferent inhibition
• brief suppression of the motor cortex shortly after a peripheral stimulus of the ulnar nerve

Question 3

what does previous research tell us?

Answer 3

• measure at a small vacation of time points
• mainly look into rest

Question 4

what are we doing differently?

Answer 4

• we are creating a SAI time course 1.3ms - 422.4ms approx to see clear neural changes overtime and comprehensive understanding of stimulation effects
• comparing rest to Jenna a fine motor skill focusing in on FDI and TE.
