Neurons in the human cortex have 29 800 synapses on average [primary source] resulting in a total of about 3.6×10^14 synapses. Note-29,800 synapses/neuron not found in primary source. link gives "1,000 to 10,000 synapses for a "typical" neuron." For 10^13 synapses in human cortex and 10^15 synapses in human connectome (the network of elements and connections forming the human brain) see Sporns et al., 2005 PMID 16201007 p.e42 left column bottom paragraph and right column top paragraph. |
