The dentate gyrus receives input from the cortex, and sends output to the hippocampus proper

Wernicke's area and angular gyrus

Angular gyrus is the Brodmann's Area 39 and is commonly known as part of the Wernicke's area. This gyrus is responsbile for understanding written language. So, any damages to angular gyrus of your dominant hemisphere might result in "alexia" (loss the ability to understand the meaning of what you read, though you can see the words)

Angular Gyrus

The post central gyrus lies directly posterior to the precentral gyrus. Both of these gyrus are located in the brain and are also almost parallel to one another.
