What Is Neural Switchboard In BG3?
The Neural Switchboard is a device in Baldur’s Gate 3.
It allows you to connect the four parts of a brain: Speed, Emotion, Memory, and Reason.
It is located in the Necrotic Lab of the Mind Flayer Colony.
In this location, players will find a Mind Archive machine that contains the brains of various creatures.
The Neural Switchboard is part of The Foundry quest.
Moreover, you have to help a Githzerai named Zanner Toobin to destroy the Mind Flayer facility and rescue his family.
How To Use Neural Switchboard In BG3?
To use the Neural Switchboard, you need to have a special item called the Neural Node.
The Neural Node allows you to connect the four colored centers of the brain to their corresponding centers on the opposite side.
The colors are Speed (red), Emotion (blue), Memory (green), and Reason (yellow). Further, they are arranged on a web of Neural Nodes.

You need to make sure that no two centers share a node, meaning they each have to have their path to the other side.
The players can view the puzzle from above by pressing O for ease. Moreover, solving the puzzle opens a door to a secret area.
There, you can find a Mind Flayer monument and a new brain that you can use in the Mind Archive machine nearby.
You can also get a boon from the brain if you agree to purge it.

How To Obtain The Neural Node In BG3?
The players can obtain Neural Node from a corpse of a Mind Flayer named Zanner Toobin. Moreover, he was defeated by the Steel Watchers.
You can find his body in a room on the opposite side of the Foundry, past a large furnace and a conveyor belt.
You will need to fight or sneak past some enemies along the way, such as Goblins, Duergar, and Slaads.
Once you reach Zanner Toobin’s corpse, you can loot it and obtain the Neural Node.

How to Solve the Puzzle?
Once you have the Neural Node, you can return to the Neural Switchboard and insert it into the socket.
This will activate the device and reveal a puzzle that you need to solve.
You need to make sure that no two centers share a node. It means that each has to have their path to the other side.
The puzzle has multiple solutions, but one possible way to solve it is as follows:
- Connect Speed (red) from the left side to the opposite side by using the nodes on the top row. However, you have to light up the red center on the right side.
- Connect Emotion (blue) from the left side to the opposite side by using the nodes on the bottom row. However, you have to light up the blue center on the right side

- Connect Memory (green) from the left side to the opposite side by using the nodes on the middle row. However, you have to light up the green center on the right side.
- Connect Reason (yellow) from the left side to the opposite side by using any remaining nodes that are not occupied by other colors. However, you have to light up the yellow center on the right side.
Further, you can check if you have solved the puzzle correctly by looking at the lights on each center.
If they are all lit up, then you have successfully connected them. If not, then you need to adjust your connections until they are all lit up.

The Bottom Line
Hence, solving the puzzle opens a door to a secret area with a Mind Flayer statue and a brain.
The brain belongs to an ancient Illithid queen whose memories you can access and erase.
However, erasing her brain gives you a boost to one of your mental attributes.
