While it is almost impossible to list every discipline, some common STEM areas include: aerospace engineering, astrophysics, astronomy, biochemistry, biomechanics, chemical engineering, chemistry, civil engineering, computer science, mathematical biology, nanotechnology, neurobiology, nuclear physics, physics, and robotics, among many, many others.
Presynaptic neurons are the neurons that conduct the AP to release a neurotransmitter and they affect the postsynaptic neurons. What ALWAYS causes a neuron to release any neurotransmitter (whether it is excitatory or inhibitory) is an action potential.ontrast that with exitatory NTs: All excitatory neurotransmitters cause an opening of ligand-gated sodium ion channels. The inhibitory NT could also cause an opening up of ligand-gated Chloride Ion channels.
Types of Neurotransmitters:- Neurotransmitters are of two types that is inhibitory and excitatory. Inhibitory neurons are responsible for calming the brain and create balance like balance in mood. They can easily be replaced by excitatory neurotransmitters when they are overactive.
