As a cognitive neuroscientist with a keen interest in the intricate workings of the human brain, I am often asked about the neural underpinnings of attention. Attention is a complex cognitive process that enables us to selectively focus on certain stimuli while ignoring others. It is a multifaceted phenomenon that involves various brain regions working in concert to filter, prioritize, and modulate sensory information.
The posterior part of the parietal lobe is indeed a critical player in the attentional network. It is particularly involved in the spatial aspects of attention, such as directing our focus to different parts of the visual field. This region is often referred to as the intraparietal sulcus (IPS) and is known to integrate sensory information with spatial cues to guide attention and eye movements.
However, it's important to note that attention is not solely the domain of the parietal lobe. The frontal lobes, particularly the anterior cingulate cortex (ACC) and the dorsolateral prefrontal cortex (DLPFC), also play pivotal roles in attention. The ACC is involved in alerting and maintaining attention, while the DLPFC is implicated in the top-down control of attention, allowing us to focus on relevant information and ignore distractions.
Moreover, the superior parietal lobule and the temporoparietal junction are regions that have been linked to the orienting of attention, which is the process of shifting our focus to novel or behaviorally relevant stimuli.
The left parietal lobe, as mentioned, has been associated with functions such as reading, writing, arithmetic, and the performance of learned information. This is partly due to its role in integrating linguistic and numerical information with spatial attention, which is essential for these cognitive tasks. Additionally, the left hemisphere is often dominant for language processing, which includes speech production and comprehension.
It's also worth mentioning the role of the thalamus, a subcortical structure that acts as a relay station for sensory and motor signals. The thalamus is involved in the modulation of attention by influencing the flow of information to the cortex.
In summary, attention is a complex cognitive function that is regulated by a network of brain regions, including but not limited to the parietal lobe, frontal lobes, and subcortical structures like the thalamus. These areas work together to filter, prioritize, and direct our focus to the most relevant aspects of our environment.

The posterior (back part) of the parietal lobe is responsible for attention. The left parietal lobe is responsible for reading, writing, arithmetic, and The Mild Traumatic Brain Injury Workbook performance of learned information. Its other function is speech.
