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.

Neurotransmitters â¢There are dozens of different neurotransmitters(NT) in the neurons of the body.â¢NTs can be either excitatory or inhibitoryâ¢Each neuron generally synthesizes and releases asingle type of neurotransmitterâ¢The major neurotransmitters are indicated onthe next slide.
