Reading Part II

Let us follow up on last weeks newsletter on reading as a cultural advantage and a human need in truth. What do we know about the neuroscience of reading dysfunction or weakened ability to achieve the goal of reading proficiency? What is the frequency of concern?

Depending on the study, 5-10% of children have reading issues like dyslexia. This has profound lifelong consequences if these issues are not dealt with in the early years of education.

Let us start again by looking at the neuroanatomy of the human reading interface. The first point of human involvement in reading is visual acceptance of the written word on page. In order to complete this task one must be able to see the word clearly in the order that it is displayed on the page and then send the neuroception to the brain via the optic nerve to the visual cortex. Then the angular gyrus interprets the words leaving the frontal lobes to engage in decoding and comprehending the information. This intricate interplay of neural networks not only facilitates the understanding of written language but also strengthens cognitive functions such as memory in the hippocampus, attention in the prefrontal cortex, and critical thinking in the neocortex...plus a piece on exercise.
