Assertion (A) : Scientists found activation in pre-frontal cortex neurons involved in planning motor actions whenever a monkey in their experiment saw a picture of a peanut.
Reason (R) : The mirror neurons respond to actions that the animal plans and performs itself and also to the same actions performed by others. These are likely to play a role in learning by observation.

Assertion (A) Analysis
The assertion states that scientists observed activation in pre-frontal cortex neurons involved in planning motor actions when a monkey saw a picture of a peanut. This aligns with neurological principles where visual stimuli associated with potential actions (like eating a peanut) can activate neural circuits responsible for planning those actions.
Reason (R) Analysis
The reason describes mirror neurons. These neurons are known to activate both when an individual performs an action and when they observe the same action being performed by others. Their role in understanding actions and facilitating learning through observation is a key concept in neuroscience.
Relationship Between Assertion and Reason
Assertion (A) describes a specific observation: seeing a peanut picture leading to motor action planning activation. Reason (R) provides a general mechanism: mirror neurons linking observed actions to motor systems and learning.
- Seeing the peanut (Assertion A) is an observation.
- This observation is linked to the potential action of eating the peanut.
- Mirror neurons (Reason R) are believed to bridge the gap between observing an action or object associated with an action and activating the motor planning circuits for that action.
Therefore, the function of mirror neurons as described in Reason (R) provides a plausible explanation for the observed neural activation in Assertion (A).
Conclusion
Both Assertion (A) and Reason (R) are factually correct statements. Furthermore, the explanation provided in Reason (R) about mirror neurons directly supports and explains the observation detailed in Assertion (A).
