a: nerve cell ~
b: a receiver
What:
"A nerve cell is like a receiver, transmitter and transmission line with the task of passing a signal along from its dendrites to the axon terminal bundle."

a: nerve cell ~
b: a long thin wire
What:
"A nerve cell is like a long thin wire. The nerve cell carries an electrical signal from one end to another, like a wire. If I touch a hot stove with my finger, a signal is initiated. That signal travels up my arm until it hits the end of the cell. At the end of the cell is a small space. "

a: Nerve cell ~
b: a manifold logic gate
What: "To better understand how the brain could perform higher level thought processes, consider the example of a binary logic gate. A nerve cell is like a manifold logic gate where, at any time, the decision to fire (corresponding to the "true" value of a binary gate) depends on whether or not the localized potential of the cell is somewhere above a threshold level. In a computer, the values of logic gate operands are also dependent on time, but they only change synchronously and at regular intervals. In a nerve cell, operands (the localized potentials of post--synaptic dendrites) are continuous values which peak and fade asynchronously. Thus a cell receiving localized potentials from seven different synapses could fire one time and not fire the next, only because during the second time one of the seven potential changes occurred at a slightly later time than it did during the first time.

a: nerve cell ~
b: a tree
What:
"Neuroscientists need a diagram of the brain's internal wiring, but mapping neural circuits isn't easy. The human neocortex houses dozens of types of neurons, all intimately intertwined. Each nerve cell is like a tree, with a head of fine branches -known as dendrites - that receive messages from several hundred to thousands of neighbors, and with a complex array of roots that pass the signals on to other cells across synapses "

METAMIA is a free database of analogy
and metaphor. Anyone can contribute or search.
The subject matter can be anything.
Science is popular, but poetry is encouraged.
The goal is to integrate our fluid muses with
the stark literalism of a relational database.
Metamia is like a girdle for your muses,
a cognitive girdle.
