I finally got my neural network piece on my 25th birthday this year.
Two neurons connected by an axon. It's even got a synaptic gap!
3 meanings from this symbol in reductionist terms:
1) Neurons are part of a network, they all have to communicate with each other and work as a unit ("The whole is greater than the sum of its parts"), much like a community.
2) Represents my brain maturing and critical understanding of young children and inevitably myself and others through neurobiology/temperament
3) Synaptic gap=leap of faith. No synapses actually touch, electro-chemicals must jump the gap to deliver message.
Also, note the thick myelin (repetition/experience strengthens the axon)
I'm looking forward to this year like no other. I feel mid-20's will be like a toddler/teenager stage of human development where I can feel the power of my autonomy and impact in my micro and macro system, but I've still got a lot of learning to do. Though my mileage is racking up, with each year passing, I feel my spirit staying the same or becoming "younger."
