**Core Concept**
The basal ganglia are a group of subcortical structures involved in movement control and cognition, including aspects of learning and memory. They play a crucial role in the regulation of motor movements, habit formation, and procedural memory.

**Why the Correct Answer is Right**
Procedural memory, also known as implicit memory, is a type of long-term memory that involves learning and remembering skills and habits. The basal ganglia are essential for the consolidation of procedural memories, which are automatic and unconscious, such as riding a bike or playing a musical instrument. The basal ganglia circuitry, particularly the caudate nucleus and putamen, is involved in the processing and storage of procedural memories.

**Why Each Wrong Option is Incorrect**
**Option A:** **Working Memory** - Working memory is a type of short-term memory that involves the temporary holding and manipulation of information. It is not directly associated with the basal ganglia.
**Option B:** **Declarative Memory** - Declarative memory, also known as explicit memory, involves the storage and retrieval of factual information. It is primarily associated with the hippocampus and temporal lobe structures, not the basal ganglia.
**Option C:** **Spatial Memory** - Spatial memory involves the ability to navigate and remember spatial relationships between objects. While the basal ganglia may contribute to some aspects of spatial memory, it is not their primary function.

**Clinical Pearl / High-Yield Fact**
The basal ganglia are often affected in neurodegenerative diseases such as Parkinson's disease, Huntington's disease, and dystonia, leading to motor symptoms and cognitive impairment.

**Correct Answer:** C. Spatial Memory
