How many
connections can a neuron have?
Reference: Paul King,
The neuron with the highest number of connections is the Purkinje cell
in the cerebellar cortex and is believed to have up to 200,000 input
connections per neuron:
A more typical neuron is the pyramidal cell in the cerebral cortex which
is believe to have around 10,000 inputs. The tiny dots long the dendrite are
the “spines” where the input neurons connect:
Some relay cells, for example in the thalamus or spinal cord, may have
only a few connections for code signal transmission but many more modulating
inputs.
