The main horizontal septum is formed by the convergence of myosepta and is likely to be the major transmitter of muscle force to the axial skeleton.
Two major transmitter systems that control GnRH secretion are the excitatory transmitter glutamate and the inhibitory transmitter gamma amino butyric acid (GABA) [13], [14], [15], [16], [17].
5-HT is a major transmitter in BGA.
The data suggest that the SG only employs the Fmrf gene post-hatching and restricts the biosynthesis of FMRFamide, demonstrating that this peptide is not a major transmitter of the giant fiber system.
Traditionally, print media, TV and radio are the major transmitters of information from public health agencies to the public and play a large role in risk intensification and attenuation.
Although homosynaptic depression has not been emphasized as an important form of synaptic plasticity, its existence can be inferred from the fact that AMPA receptors, which are major transmitters of excitatory synaptic currents, are constantly internalized and degrade [39]; consequently, the efficacy of a synapse is reduced constantly unless it is consistently potentiated.
One in four of the study subjects lived at elevations that were higher than several of the major transmitters in this area.
GABA (gamma-aminobutyric acid) is the brain's major inhibitory transmitter, and its role, in essence, is to keep glutamate, the main excitatory transmitter, from overwhelming us.
Glutamate, the major excitatory transmitter in the brain, is the precursor for the synthesis of GABA, the major inhibitory transmitter in the adult brain.
This may lead to an increase in the extracellular concentration of glutamate, the major excitatory transmitter in the central nervous system.
Previous studies using transgenic mice [1], [2], [3], [4] or SCN slice cultures [17], [18] suggested the involvement of PACAP signaling in light- and/or glutamate (a major light transmitter)–induced phase shifts.
