Gold nanoparticles to save neurons from cell death

In a recent experiment, researchers have developed gold nanoparticles in the laboratory in order to reduce the cell death of neurons exposed to overexcitement. The study is the result of an international collaboration coordinated ...

Neurotransmitters in an instant

Dopamine, serotonin, adrenalin... The smooth functioning of the human brain depends on their correct proportions. Any disturbances mean diseases. That's why it's so important to be able to detect these disturbances as early ...

The role of GABA neurons in the central circadian clock

Neurotransmitter

Neurotransmitters are endogenous chemicals which relay, amplify, and modulate signals between a neuron and another cell. Neurotransmitters are packaged into synaptic vesicles that cluster beneath the membrane on the presynaptic side of a synapse, and are released into the synaptic cleft, where they bind to receptors in the membrane on the postsynaptic side of the synapse. Release of neurotransmitters usually follows arrival of an action potential at the synapse, but may follow graded electrical potentials. Low level "baseline" release also occurs without electrical stimulation.
