The process of deciphering information conveyed by neurons in the human brain is known as neural coding. Conventionally, it has been done by considering how neurons change their rate of firing ...
By optically controlling the activity of pyramidal cells, we demonstrate that these excitatory neurons induce vasoconstriction when their action potential firing is increased by releasing glutamate ...
But in humans, the technical challenges of identifying and analyzing new neurons in adult brains, combined with their rarity, had led scientists to doubt their significance to brain function.
A team of neurologists, bioengineers and radiologists has found that two neurons in the human brain that code for dopamine production have to work harder than similar cells in primate relatives.
