- In the study of human neurophysiology, there are many neurotransmitters which have significant roles in the normal functioning of central nervous system and peripheral nervous system processes. One particular molecular compound is the major excitatory neurotransmitter of the peripheral nervous system and at the neuromuscular junctions. This particular neurotransmitter also has a major role in the formation and retention of long-term memory in the brain and gradual loss of this particular neurotransmitter in the basal nucleus of Meynert is most likely associated with the development of which of the following medical conditions?
- Which of the following molecular compounds is the most likely major excitatory amino acid neurotransmitter in the brain which plays a role in pain transmission via Aδ and C fibers and is hypothesized to be involved in consolidating short-term to long-term memory formation via long-term potentiation of hippocampal neurons through activation of N-methyl-D-aspartate receptors?
- Neurotransmitters have an essential role in normal functioning of the nervous system and gradual loss or imbalances of one or more of these key neurotransmitters are generally associated with the development of certain medical conditions. Which of the following molecular compounds is the most likely neurotransmitter released by postganglionic neurons in the sympathetic division of the autonomic nervous system as well as being theoretically involved in the complex formation and maintenance of psychological mood and neuroanatomically located in the highest concentration within the locus ceruleus of the central nervous system?
