Neuron
A neuron is the basic cell of the nervous system specialized in receiving, processing and transmitting signals.
Definition
It usually consists of a cell body, dendrites and an axon. It transmits information through electrical impulses and chemical communication at synapses. The individual neuron is important, but emotions, behavior and thinking result from the operation of complex networks.
Key ideas
- Nerve cell
- Impulse and synapse
- Neural networks
Practice and life
When learning about the brain, avoid sentences like "one neuron causes X." Search for network description, connections and context.
Common misconceptions
It is a mistake to reduce complex behaviors to single cells. The second mistake is to ignore the role of the network and environment.
