Hold that thought? Scientists find sensor that may explain working memory
(Medical Xpress) -- In many cases, a delay occurs between the time you are presented information and the time you respond with an action or decision. Most of us call it a thought, while some scientists call it working memory.

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.
