Using touch to discern shapes
In this part of the simulation you will "record" the neural activity from an afferent fiber as well as neurons in area 3b and 1 of the primary somatic sensory cortex, all with receptive fields on the tip of the left index finger. The black dots on the paper represent an embossed braille letter.
Click on one of the arrows to the left of the paper to smoothly glide the finger along the page. You can choose which neuron's activity you would like to hear by selecting the desired radio button in the box.
You can click on each arrow as many times as you want to generate a new trial. A "spatial event plot" for each neuron will appear on the smaller papers in the box.
If your eyes were closed, would you be able to tell which braille letter was on the paper by just listening to one of these neurons? If so, which one(s)?
