The brain is a complicated network of small units called
neurons, all working to carry information from the outside world, create an
internal model, and generate a response. Neurons sense a signal through
branching dendrites, carry this signal to the cell body, and send it onwards
through a long axon to signal the next neuron. However, neurons can function in
many different ways; some of which researchers are still exploring. Some
signals that the dendrites receive do not continue to the next neuron; instead
they seem to change the way that the neuron handles the subsequent signals.
This could help neurons function as part of a large network, but researchers
still have many questions
