Denise Schmandt-Besserat, “How Writing Came About”, 1992 was the topic of an earlier blog post.

INTRODUCTION.
The “Intraparietal Sulcus” (IPS) is located on the lateral surface of the parietal lobe, and consists of an oblique and horizontal portion (shown “color red”ABOVE).
The “Intraparietal Sulcus” (shown “color red” ABOVE) is associated with the disorder “Dyscalculia” (number sense deficiency).
“Dyscalculia” is a disability resulting in difficulty learning or comprehending arithmetic, such as difficulty in using numbers, learning how to manipulate numbers, performing mathematical calculations, and learning facts in mathematics.

COMMENTS.
“Finger agnosia” is often associated with the deficit “Dyscalculia”.
”Finger agnosia” is the inability to name, move, or touch specific fingers identified by an examiner.
“Dyslexia” (readless) is a comorbidity usually seen in cases of “Dyscalculia” (number blindness).
Brian Butterworth’s “… the Origins of Dyscalculia”, 2010 are part of the history of Learning and Schools.
