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.
