The origin and evolution of synapses
Webb8 juni 2008 · Understanding the origins and evolution of synapses may provide insight into species diversity and organisation of the brain. Using comparative proteomics and genomics we examined the evolution of the postsynaptic density (PSD) and MAGUK associated signalling complexes (MASCs) underlying learning and memory. WebbAt a synapse, one neuron sends a message to a target neuron—another cell. Most synapses are chemical; these synapses communicate using chemical messengers. …

WebbA corollary of the independent origin of neurons from ancestral secretory cells is the convergent evolution of synapses and synaptic signaling. Indeed, the eukaryotic exocytosis machinery (formation and the release of secretory vesicles) can independently recruit various uptake systems (transporters) and receptor proteins.
