If damage to basal ganglia, what is the result?

• A. Heightened Senses
• B. Increased Appetite
• C. Tremors and Slow Movement
• D. Improved Memory

Answer: (C)

The basal ganglia help regulate the initiation and smooth execution of voluntary movements and maintain appropriate muscle tone. When these circuits are disrupted, movement becomes hard to start and coordinate, leading to motor symptoms like tremors, slower voluntary movements (bradykinesia), and stiffness or rigidity. This pattern is characteristic of conditions such as Parkinson's disease, where loss of dopamine in this pathway reduces the system’s ability to modulate motor signals.

So the outcome of basal ganglia damage is tremors and slow movement. Heightened senses, increased appetite, and improved memory aren’t typical consequences of basal ganglia dysfunction—these functions are driven by other brain regions (sensory processing, hypothalamic regulation, and memory systems, respectively).
