Neurotransmission: The Secret Life of Memory Receptors
The human brain contains around 86 billion neurons thatcommunicate with each other through electrical and chemical signals. In the signaling neuron, an electrochemical event known as an action potential, or spike, triggers the release of molecular messengers into the synaptic cleft between two connected neurons. These neurotransmitters are then detected by postsynaptic receptors in the recipient cell. As information in the brain generally flows from the pre- to the postsynaptic neuron, it might seem unlikely to find any neurotransmitter receptors on the presynaptic, transmitting side. The Secret Life of the Brain is a collection of five one hour-long videos that dramatize the brain from before birth, through childhood, adolescence, adulthood, and aging. Each episode focuses on a specific aspect of the brain and its resulting behavior during that developmental stage.
