White matter dissection

White Matter Dissection is a neuroanatomical technique used to study the brain's intricate network of neuronal connections. This method is crucial in understanding the complex neuroanatomical structures and their functional implications in both health and disease.

Overview

White matter dissection of the brain

White matter dissection involves the careful separation of white matter tracts in the brain. These tracts are bundles of axons, which are long extensions of neurons that transmit electrical signals between different parts of the brain. The white matter gets its name from the white, fatty myelin sheath that insulates these axons.

Techniques

The process of white matter dissection begins with the fixation of the brain in a solution of formaldehyde. This is followed by the careful removal of the grey matter, revealing the underlying white matter tracts. The dissection is typically performed using a microscope and fine instruments, such as forceps and micro-scissors.

Applications

White matter dissection is used in various fields of neuroscience, including neuroanatomy, neurology, and neurosurgery. It is particularly useful in the preoperative planning of neurosurgical procedures, as it allows surgeons to visualize the exact location of white matter tracts and avoid damaging them during surgery.
