Latest Chemical synapse Stories
Transmission of nerve signals is enhanced in the insects that eat less
UC Santa Barbara scientists turned to the simple sponge to find clues about the evolution of the complex nervous system and found that, but for a mechanism that coordinates the expression of genes that lead to the formation of neural synapses, sponges and the rest of the animal world may not be so distant after all.
The brain receives information from the ear in a surprisingly orderly fashion.
Researchers have shown in mice how immune cells in the brain target and remove unused connections between brain cells during normal development.
Scientists at Weill Cornell Medical College have discovered that the single protein -- alpha 2 delta -- exerts a spigot-like function, controlling the volume of neurotransmitters and other chemicals that flow between the synapses of brain neurons.
How do we build a memory in the brain?
Scientists now have a better understanding of how precise memories are formed thanks to research led by Prof. Jean-Claude Lacaille of the University of Montreal's Department of Physiology.
University of Iowa biologists have advanced the knowledge of human neurodevelopmental disorders by finding that a lack of a particular group of cell adhesion molecules in the cerebral cortex—the outermost layer of the brain where language, thought and other higher functions take place —disrupts the formation of neural circuitry.
They say you can’t teach an old dog new tricks.
Certain genes and proteins that promote growth and development of embryos also play a surprising role in sending chemical signals that help adults learn, remember, forget and perhaps become addicted.

- A sleeping-potion; a soporific.
