The Fields of Forel are a group of white matter structures located in the subthalamus region of the brain. They are named after the Swiss neuroanatomist Auguste Forel. These fields are involved in the extrapyramidal system, which is responsible for the modulation and regulation of motor control.

Anatomy

The Fields of Forel are divided into three distinct areas:

• Field H: Also known as the H field, it is located in the zona incerta and is involved in the integration of sensory and motor signals.
• Field H1: This field is part of the thalamic fasciculus and is involved in the transmission of motor signals from the globus pallidus to the thalamus.
• Field H2: Known as the lenticular fasciculus, it carries fibers from the globus pallidus to the subthalamic nucleus.

Function

The Fields of Forel play a crucial role in the extrapyramidal system, which is essential for motor control and coordination. They are involved in the regulation of voluntary movement and the integration of motor signals from different parts of the brain.

Clinical significance

Damage or dysfunction in the Fields of Forel can lead to movement disorders such as Parkinson's disease and Huntington's disease. These conditions are characterized by tremors, rigidity, and involuntary movements.
