Neuroanatomical Model
Neuroanatomy is that the study of the connection between structure and performance within the systema nervosum . Neuroanatomy also includes the study of macroscopic and microscopic structures. Macroscopic structures are larger structures, such as folds of the brain. On the opposite hand, microscopic structures include those at the cellular and molecular level, like interactions between
neurons and glia. Three components form the foundation of the nervous system:
neurons (or nerve cells), neuroglia (glial cells) and extracellular constituents.
Neurons process
information by sensing the environment, communicating through neurotransmitters, and originating our thoughts and memories.
Neurons have a cell body (soma) and two sorts of extensions, or processes. One is called a dendrite, and the other one is an axon.
Neurons usually have quite one dendrite and one axon. The
brain is constituted of multiple networks of functionally correlated
brain areas, out of which the default-mode network (DMN) is the largest. Most existing research into the DMN has taken a corticocentric approach. Despite its resemblance with the unitary
model of the visceral
brain , the contribution of subcortical structures to the DMN could also be underappreciated. At the organ level, the systema nervosum consists of
brain regions, like the hippocampus in mammals or the mushroom bodies of the pomace fly .These regions are often modular and serve a specific role within the overall systemic pathways of the systema nervosum . For example, the hippocampus is critical for forming memories in reference to many other cerebral regions.
