WitrynaThese are a part of your reticular activating system (nuclei plus the white matter connecting these nuclei), which lies in your brainstem, hypothalamus and thalamus. The reticular activating system (RAS) mediates your level of awareness, consciousness and focus. They also help control your sleep-wake transitions and autonomic function.
WitrynaSo what happens is the following: 1) A stimulus activates a receptor. 2) The receptor transmits the signal to an afferent pathway. 3) The afferent pathway carries the signal to a place (e.g. spinal cord) where this pathway synapses (or communicates with) the efferent pathway. WitrynaGlutamate is the primary excitatory neurotransmitter in the nervous system. Glutamate channels are connected to many other neurotransmitter pathways, and glutamate receptors are located in the brain and spinal cord in neurons and glia. As an amino acid and neurotransmitter, glutamate has a broad spectrum of natural physiological roles.
