The atmosphere is quite dusty, giving the Martian sky a light brown or orange-red color when seen from the surface; data from the Mars Exploration Rovers indicate that suspended dust particles of roughly 1.5 micrometres diameter.
Glutamate is a powerful excitatory neurotransmitter that is released by nerve cells in the brain. It is responsible for sending signals between nerve cells, and under normal conditions it plays an important role in learning and memory.
Glutamate is the most abundant excitatory neurotransmitter in the human brain. It plays key roles in cognitive functions like learning and memory. Imbalances in glutamate levels are associated with Alzheimerâs disease, seizures and forms of autism.lutamate is the most abundant excitatory neurotransmitter in the human brain.
