W12 Neuro arm paper Flashcards
(12 cards)
what can the BCI system help to do
restore tactile sensation to arms
how does the BCI system do what it does
intracortical microstimulation (ICMS) of the somatosensory cortex
why does the findings counter webers law
stimulation intensity and perceived sensation was linear
what was the methods used in the experiment
- prosthetic hand equipped with torque sensors could detect changes in pressure
- tested the improvement to manipulation tasks
what were the control stimulations of ICMS
electrode locations
pulse amplitude
frequency
duration
why would error bars in a graph not be asymmetric
use of non-parametric statistics or skewed data
for Science published papers where can you find the methods
in the materials page
what was being stimulated on the bionic hand torques
electrodes with the use of electrical stimulations
why would the median be used for neuro data
to avoid outliers
what are the conclusions of the paper
ICMS is able to provide tactile feedback and sensory feedback
what is webers law
noticing a change is stimuli will be proportional to the size of the original stimuli known as the JND
why does ICMS defer webers law
subject can tell the difference in stimuli change regardless of original stimuli size
