Hey Everybody! I recently made this new brain/neuron fabric and gift wrap! I made a giant brain pillow for my psychiatrist too, and he seemed to like it which was awesome! :) Here are some pics! Also, the fabric, gift wrap, and wall paper are available on spoonflower here: http://www.spoonflower.com/fabric/3713721
This is my third drawing for neuroscience class and it is showing the voltage changes and what is going on during the time when a neuron fires. The resting potential is about -70 millivolts, it shoots up to about +30 millivolts and then comes back down below the resting potential before it returns to the resting potential of -70 mV. This all happens in about 1-5 milliseconds depending on the particular neuron. FAST! :) Oh, also keep in mind that we have about 100-500 BILLION neurons in our heads too and nine times as many glial cells!!!
