SAN DIEGO, Oct. 24 -- Recent advances are producing a much greater understanding of the brain circuits responsible for the tics and problem behaviors seen in Tourette's syndrome. In one groundbreaking ...

Basal ganglia calcification is when calcium deposits form in your brain. It can potentially cause a variety of neurological symptoms and can affect mood, perceptions, and behavior. The basal ganglia ...

‌Chorea is a movement disorder that stems from something wrong with the basal ganglia nerve structure deep in your brain. It causes involuntary movements of the hands, feet, and face. These movements ...

The basal ganglia play a critical role in regulating movement, cognitive functions and emotional processing. Disruptions within these subcortical nuclei are increasingly attributed to defects in ...

Thousands of our daily activities, from making coffee to taking a walk to saying hello to a neighbor, are made possible through an ancient collection of brain structures tucked away near the center of ...

I started having tics when I was 7 years old. At first, doctors dismissed my mom's concerns as me just being a kid. Tourette syndrome can't be cured, but I want to have more control over my tics. I’m ...

The substantia nigra is a motor nucleus located in the basal ganglia of the midbrain. This brain structure contributes to the body's cognitive and motor functions by sending signals to initiate or ...

Fast-spiking neurons in the basal ganglia allow monkeys to associate different values with the same objects based on the surrounding environment. Blocking input from these cells inhibited learning of ...

Neurons deep in the brain not only help to initiate movement-they also actively suppress it, and with astonishing precision. This is the conclusion of a new study by researchers at the University of ...

Researchers have applied a chemogenetic tool in macaque monkeys and suppressed the subthalamic nucleus, a part of the basal ganglia circuitry. The chemogenetic suppression induced unstable movements.
