So a lot of what passes for philosophical argument in the literature on ethics, is one philosopher talking past another because they are coming at the discussion with different concepts of morality. The relationship between morality and self-interest is an enduring one in the history of philosophy.
1 Neurons have TWO processes called axons and dendrites....glial cells have only ONE. 2  Neurons CAN generate action potentials...glial cells CANNOT. 3  However, glial cells do have a resting potential. 4  Neurons HAVE synapses that use neurotransmitters...glial cells do NOT have chemical synapses. However, glial cells do have a resting potential. 2  Neurons HAVE synapses that use neurotransmitters...glial cells do NOT have chemical synapses. 3  There are many MORE (10-50 times more) glial cells in the brain compared to the number of neurons.
Ammonia is very toxic to the brain and new research shows why: the glial cells ability to remove potassium is perturbed. The picture shows individual glial cells deep in the brain of live mice, as well as a microelectrode used to measure electrical activity in nerve cells subjected to two-photon laser microscopy.
