Neurons in themselves are complex structures that use electrical and molecular signals to send information to neighbouring neurons, and the brain as a whole structure.

Studies of early development in fishes show that neural networks in the brain controlling the more complex vocal and pectoral mechanisms of social signalling among birds and mammals have their ancestral origins in a single compartment of the hindbrain in fishes.

NMDA receptors are complex electrochemical machines, important for signaling between brain cells.

To achieve this goal, we developed an integrated system that enables simultaneous real - time visualization of structural reorganization in spatially - restricted signaling complexes and functional modifications of single synapses in brain circuits.

Aβ is believed to penetrate neuronal plasma membranes, where it leads to lipid peroxidation.10 It has also been implicated in deactivating a subunit of the pyruvate dehydrogenase complex, thereby inhibiting conversion of pyruvate to acetyl CoA and the eventual production of cellular energy as ATP.32 Another way Aβ affects glucose metabolism in the brain is that fragments of Aβ disrupt insulin signaling by binding to neuronal synapses, which alters their shape and function.15, 38 Insulin receptors are abundant at synapses, so if the integrity of the synapse itself has been compromised, the receptors won't function effectively.
