Schematic illustration of the effect of congenital deafness on cortical columns. (a) Schematic illustration of connectivity between layers and areas in hearing animals. Green arrow marks the driving connection between supragranular and infragranular layers, dashed lines indicate modulatory effect of the connection from infragranular to supragranular layers. (b) In congenitally deaf cats, the intracolumnar connection from supragranular and infragranular layers (green) and long‐distance connections between cortical areas are weakened and short‐range connectivity in supragranular layers is strengthened
