IEEE Spectrum has put out a short visual guide to how the brain works. In six images they nicely sum up how the 86 billion neurons do their job.
In the brain, millions of neurons are constantly activating, or firing, in complicated sequences. Neuroscientists are just beginning to decipher this neural code and to link firing patterns to sensations, actions, and feats of cognition.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
