Neurodevelopment of somatosensory (pain, temperature, and touch) systems
Appreciating a hot coffee requires cycles of neurodevelopmental construction, destruction, and refinement (building neurons, circuits, and synapses) to build the neural systems to feel the hot, smooth cup, take a sip, and taste the bitter, nutty flavor.
What does it take to build a functioning brain, then? How does a brain grow to make sure each neurons knows what its job is? For instance, to detect the heat of the mug, the smoothness of the ceramic surface, or the weight of the mug in hand?
