Chemical synapses are biological junctions through which neurons’ signals can be sent to each other and to non-neuronal cells such as those in muscles or glands. Chemical synapses allow neurons to form circuits within the central nervous system.They are crucial to the biological computations that underlie perception and thought.
In physiology an action potential (AP) occurs when the membrane potential of a specific cell location rapidly rises and falls: this depolarization then causes adjacent locations to similarly depolarize. Action potentials occur in several types of animal cells called excitable cells which include neurons muscle cells endocrine cells and in some plant cells.
Synesthesia or synaesthesia is a perceptual phenomenon in which stimulation of one sensory or cognitive pathway leads to involuntary experiences in a second sensory or cognitive pathway. People who report a lifelong history of such experiences are known as synesthetes.Awareness of synesthetic perceptions varies from pers…
