Neuron

Why was it so hard to establish that the neuron is the most basic unit of nervous tissue?

Not a single neuron appeared to be firing.

In the laboratory there is a piece of abstract art that is composed of images of neuron networks, showing their vast complexity.

A neuron has dendrites and axons with synapses.

The yawning gap in neuroscientists’ understanding of their topic is in the intermediate scale of the brain’s anatomy. Science has a passable knowledge of how individual nerve cells, known as neurons, work. It also knows which visible lobes and ganglia of the brain do what. But how the neurons are organised in these lobes and ganglia remains obscure.
