Corpora striata of the cerebrum are

Options

A. Tracts of grey matter
B. Ganglia of white matter
C. Basal nuclei of white matter
D. Nerve of white matter

Answer

### Step-by-Step Solution:

1. **Understanding Corpora Striata**: The corpora striata are clusters of neurons located in the forebrain. They are a significant part of the brain's basal ganglia.

2. **Location**: Specifically, the corpora striata are found in the cortical basal ganglia area of the forebrain.

3. **Structure**: The corpora striata is the largest structure within the basal ganglia and is divided into two main parts: the dorsal striatum and the ventral striatum.

4. **Components**: The dorsal striatum is further divided by the internal capsule into two components: the caudate nucleus and the putamen. The lentiform nucleus is also part of the corpora striata.

5. **Function**: The corpora striata play a crucial role in coordinating multiple aspects of cognition, including motor and action planning, decision-making, motivation, reward perception, and reinforcement.

6. **Correct Option**: Based on the above information, the correct definition of the corpora striata of the cerebrum is that they are the basal nuclei of white matter.

### Final Answer:
The corpora striata of the cerebrum are **basal nuclei of white matter**.
