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
The Boston process approach of the main modifications are listed below: The Boston process approach is known to be a flexible battery approach when assessing brain function of a person, meaning that there can be many different standardized tests that can be administered to the individual depending on their existing deficiencies. Data interpretation from this approach does not necessarily look at the final score on the tests, rather it focuses on what kind of errors were made by the individual during the assessment. Results from the Boston process approach allow the clinician to make inferences about what brain areas may not be working properly
