Interneuron Potentiation

Simple_Potentiation

Neurons are though to encode memories by changing the strength of synapses. Very generally, the more a presynaptic neuron signals a postsynaptic neuron, the more likely that postsynaptic neuron is to fire an action potential in response to future signaling. NeuroBytes interneurons incorporate this kind of synaptic potential to encode memories. When in memory mode, high frequency input signals increase interneuron synaptic strength, and make the neuron more likely to fire an action potential in response to future inputs. This is indicated by a magenta LED that increases in brightness to indicate the level of potentiation.

Insecure NeuroBuggy

When Insecure is put down in an open area, the right wheel only will be moving forward, and the NeuroBuggy will be driving in counter-clockwise circles. If it is put down with a wall on its left however, the NeuroBuggy will move forward and left, bumping into the wall. This will activate the Touch Sensory Neuron on the left front of NeuroBuggy, which will activate the left Motor Neuron, and cause the left wheel to rotate forward. This will move the NeuroBuggy slightly away from the wall, deactivating the Touch Sensory Neuron, and the cycle begins again.

Paranoid NeuroBuggy

Paranoid has 1 rod photoreceptor that it uses to navigate its environment. It uses two interneurons and two motor neurons to do so, but the two sides of the circuit are connected a bit differently. The "light" output on the rod drives both wheels forward, while the dark output drives just the left wheel backward. This results in a NeuroBuggy that follows the edge of a light halo.

Stubborn NeuroBuggy

Stubborn has paired two neuron oscillators on it. When the front touch sensory neuron is activated, the touch inhibits the "forward" oscillator and activates the "backwards" oscillator. When the rear touch sensory neuron is activated, the opposite happens. This circuit causes the NeuroBuggy to run back and forth between two objects.
