Which part of the brain is a major coordinating centre for sensory and motor signaling ?

Options

A. Associating area
B. Thalamus
C. Hypothalamus
D. Limbic system

Explanation

To answer the question "Which part of the brain is a major coordinating centre for sensory and motor signaling?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Brain Structure**: The human brain is divided into three main parts: the forebrain, midbrain, and hindbrain. Each part has specific functions and structures.

2. **Identifying the Forebrain Components**: The forebrain is further divided into several important structures, including the cerebrum, thalamus, and hypothalamus.

3. **Examining the Options**:
- **Association Area**: This area is located in the cerebral cortex of the cerebrum. It is involved in integrating sensory and motor information but is not primarily a coordinating center.
- **Thalamus**: This structure is located beneath the cerebral cortex and acts as the major relay station for sensory and motor signals, coordinating information before it reaches the cerebral cortex.
- **Hypothalamus**: This part of the brain is involved in regulating autonomic functions and homeostasis but is not primarily a coordinating center for sensory and motor signals.
- **Limbic System**: This system is involved in emotions and memory but does not serve as a major coordinating center for sensory and motor signaling.

4. **Conclusion**: Based on the analysis of the options, the thalamus is identified as the major coordinating center for sensory and motor signaling in the brain.

### Final Answer:
The part of the brain that is a major coordinating centre for sensory and motor signaling is the **Thalamus** (Option 2).
