A new study challenges long-held beliefs about how learning occurs. Researchers suggest learning occurs in dendrites that are in close proximity to neurons, as opposed to occurring solely in synapses.
The brain is a complex network containing billions of neurons, where each of these neurons communicates simultaneously with thousands of other via their synapses (links). However, the neuron actually collects its many synaptic incoming signals through several extremely long ramified “arms” only, called dendritic trees.
