Final answer:
The right inferior frontal gyrus is responsible for planning, judgment, reasoning, and working memory. It plays a crucial role in decision-making and cognitive functions.
Step-by-step explanation:
The right inferior frontal gyrus is a part of the prefrontal cortex that is responsible for planning, judgment, reasoning, and working memory. It plays a crucial role in decision-making and cognitive functions. For example, when faced with a problem, this region helps in evaluating different solutions and making a choice based on judgment and reasoning.
A study using brain scans found that the right inferior frontal gyrus is involved in different tasks. In one task, participants were asked to find similarities between pairs of words, such as 'apple and orange.' The activation in this region was higher when participants were engaged in this semantic task compared to a perceptual task.
Damage to the right inferior frontal gyrus can result in changes to personality, mood, and behavior. This is evidenced by famous cases like Phineas Gage, who experienced a drastic change in personality after sustaining damage to this region.
