Nervous system would not exist without the human brain. Most neurons send signals via their axons, although some types are capable of dendrite-to-dendrite communication. (In fact, the types of neurons called amacrine cells have no axons, and communicate only via their dendrites.) Neural signals propagate along an axon in the form of electrochemical waves called action potentials, which produce cell-to-cell signals at points where axon terminals make synaptic contact with other cells. Synapses may be electrical or chemical. Electrical synapses make direct electrical connections between neurons, but chemical synapses are much more common, and much more diverse in function. At a chemical
Educational neuroscience In return, it is difficult for neuroscientists to characterize such interactions in a research setting. The Horizontal Problem: Translating research findings: While education theory and data are almost exclusively behavioral, findings from neuroscience research can take on many forms (e.g. electrical, chemical, spatial, temporal etc.). The most common form of data taken from neuroscience to education is the spatial mapping of brain activation to cognitive function. Willingham (2009) highlights the difficulty in applying such spatial information to educational theory. If a certain brain region is known to support a cognitive function relevant for education, what can actually be done with
