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.
[v]. Glutamate, a neurotransmitter known for exciting neurons, is very important in helping to propagate neural signals in the brain. But research has linked its receptors to a variety of neurodegenerative diseases, including Alzheimerâs, Parkinsonâs, and Huntingtonâs diseases.v].
