The frontal lobe is the part of the brain that helps people to organize, plan, pay attention, and make decisions. Parts of the frontal lobe may mature a few years later in people with ADHD. The frontal lobe is the area of the brain responsible for: Problem Solving.
Meticulous research over decades has found that the control of this vital ability, called selective attention, belongs to a handful of areas in the brain’s parietal and frontal lobes. Now a new study suggests that another area in an unlikely location—the temporal lobe—also steers the spotlight of attention.
The cerebral cortex is the part of the brain that is associated with our memory, thought, attention, awareness, and consciousness. This is also, where concentration comes into play.
Attentional control refers to an individual’s capacity to choose what they pay attention to and what they ignore. … Primarily mediated by the frontal areas of the brain including the anterior cingulate cortex, attentional control is thought to be closely related to other executive functions such as working memory.
Focused Attention: Refers to our ability to focus attention on a stimulus. Sustained Attention: The ability to attend to a stimulus or activity over a long period of time. Selective Attention: The ability to attend to a specific stimulus or activity in the presence of other distracting stimuli.
Frontal Lobe: Front part of the brain; involved in planning, organizing, problem solving, selective attention, personality and a variety of “higher cognitive functions” including behavior and emotions.
These findings suggest that the parietal cortex plays an important role in shifts of attention in space. Functional neuroimaging studies of normal subjects have frequently observed enhanced activations in the parietal, frontal, and cingulate areas in association with spatial attention.
Your brain directs focus capability by filtering important information and moving it up the ladder for deeper processing while suppressing interruptions from irrelevant bits and pieces — a function known as efficient selection.
That’s why it’s sometimes called a chemical messenger. Dopamine plays a role in how we feel pleasure. It’s a big part of our unique human ability to think and plan. It helps us strive, focus, and find things interesting.
Recent brain imaging studies using functional magnetic resonance imaging (fMRI) have implicated a frontal-parietal network in the top-down control of attention.
The prefrontal cortex is a part of the brain located at the front of the frontal lobe. It is implicated in a variety of complex behaviors, including planning, and greatly contributes to personality development.
We review two studies aimed at understanding the role of prefrontal cortex (PFC) in the control of attention. … Taken together, our findings indicate that both frontal and parietal cortices are involved in generating top-down control signals for attentive switching, which may then be fed back to visual processing areas.
An attention span is a measure of the amount of time someone can stay focused on a particular task, thought, or conversation without being distracted.
The human brain is able to focus up to two hours, after which it needs a 20-30 minute break. The average American spends about 9 hours a day at work. According to the NeuroLeadership Institute, work focus equals about 6 hours a week.
In addition to modulating firing rate, attention has been found to influence neural activity in other ways. Focusing attention increases the synchronization of local field potentials (LFPs; thought to represent synaptic input) in V4 (Fries et al.
Specifically, the dorsal posterior parietal and frontal cortex region are mainly implicated with voluntary attention, while activity is transiently shown in the occipital region. The endogenous mechanisms are thought to integrate previous knowledge, expectations and goals to voluntarily decide where to shift attention.
The insular cortex, which separates the frontal and temporal lobes, has long been thought to be the primary sensory area for taste. It also plays a role in other important functions, including visceral and emotional experience. “The insular cortex represents experiences from inside our bodies,” Anderson said.
Function of the posterior cortex
The posterior cortex is the “sensory” cortex, much as the frontal cortex is the “action” cortex. The posterior cortex is responsible for encoding the sensory content (visual, auditory, and tactile) of any experience (both real and imaginary experience).
Having too much dopamine — or too much dopamine concentrated in some parts of the brain and not enough in other parts — is linked to being more competitive, aggressive and having poor impulse control. It can lead to conditions that include ADHD, binge eating, addiction and gambling.
