Prefrontal cortex functions, cognitive and behavioural processes, emotional regulation, decision-making, and schizophrenia treatment approaches in 6009PY Clinical Neuroscience.
In two cerebral hemispheres are located the prefrontal cortex (PFC) in anterior section of the frontal lobes (Hathaway & Newton, 2023). Highly essential for processes in human thought or behaviour characterised by such higher order cognition. The anatomical part is located behind the forehead, including the dorsal lateral prefrontal cortex (DLPFC), orbitofrontal cortex (OFC), and ventromedial prefrontal cortex (vmPFC). The brain region is extensively connected with and capable of integrating information from sensory, limbic and motor systems; therefore with cortical and subcortical areas.
The innervation of PFC is very dense to a synaptic section dedicated to the complex execution (Fiske & Holmboe, 2019) and there is a high neurophysiological plasticity. Mesocortical dopamine is arguably most important, since it projects to the midbrain dopaminergic system (dopaminergic midbrain projection) which are especially dopaminergic for working memory, motivation and goal directed behaviour, and very well innervated. Furthermore, extensive communication between the PFC and the limbic system, such as the amygdala and hippocampus, has also been established, and it has also been detected in emotion regulation and decision making. Given its fundamental role in several neuropsychiatric disorders (such as schizophrenia, depression and attention deficit hyperactivity disorder [ADHD]) (Ugarte et al., 2023), the PFC has undergone a rapid focus of clinical neuroscience. This essay critically reviews the functioning of the prefrontal cortex on behavioural and cognitive functions and the dysfunction of the prefrontal cortex in schizophrenics, as explored in 6009PY Clinical Neuroscience. It provides a basis of evidence for the treatment of this disorder.

Human cognition critically depends on the prefrontal cortex, allowing for the planning, attentional focus, control of emotions, and preparation of behaviour for changing demands through social and environmental needs, a concept extensively examined in 6009PY Clinical Neuroscience (Andreassen et al., 2023). One of its core functions is the ability to hold and manipulate information temporarily in the form of working memory. It is necessary for problem-solving, reasoning and following detailed instructions. However, if this function is dysfunctional, individuals typically cannot maintain focus, organise to complete tasks or carry out multistep actions (Van Tonder et al., 2022).
The prefrontal area is also essential for inhibitory control apart from the working memory (McKeon et al., 2024). It gives people some much-needed respite to reflect and think before acting so they don’t act selfishly or do something rashly. A well-functioning prefrontal cortex suppresses automatic responses that may be inappropriate or harmful (Andreassen et al., 2023). A damaged or dysfunctional area can result in disinhibition, i.e. aggressive behaviour and impulsive or socially disruptive actions.
It also plays a vital role in making decisions, particularly in deciding whether a particular reward or risk is worth taking and how it will affect the future. Based on this, the orbitofrontal area is involved in evaluating emotional outcomes and making behavioural changes (Barron & Storch, 2021). For instance, learning from mistakes or taking risks even with negative consequences might be difficult for people with impairments in this area.
Our emotional regulation and empathy, being critical for our life, rely on the prefrontal cortex ventromedial portion. By using it, people can understand other people’s points of view and thus, answer in emotionally right way (Israelashvili et al., 2019). If there’s a fault in this area, you can expect emotional responses of being muted or exaggerated, empathising less and less. Such effects can have marked effects on interpersonal relationships and even result in social withdrawal or conflict (Barron & Storch, 2021). On a final note, the prefrontal cortex plays a role in the behavioural and cognitive play, which is a very integrally linked and necessary part of life. However, several such deficits tend to cause complex, multi-faceted symptoms, making it a big fronteir in clinical neuroscience to understand the underlying brain processes for mental health disorders (Kim et al., 2021).
One strong association with the development of schizophrenia, a chronic psychiatric disorder that influences thought, perception, emotion, and interaction, is some kind of dysfunction in the prefrontal cortex (Rosaria et al., 2019). The symptoms of schizophrenia are called positive (e.g. hallucinations and delusions), negative (e.g. reduced motivation, emotional expression), and cognitive (e.g. poor memory, attention and decision-making, and occur in all three spectrums of symptoms. Among these, the most obviously related to prefrontal cortical abnormalities are the cognitive symptoms, particularly those of the dorsolateral region (McCalley et al., 2022).

Individuals with a diagnosis of schizophrenia have common structural and functional abnormalities of the prefrontal cortex (Dabiri et al., 2022). Grey matter volume of this region is reduced consistently in imaging studies, correlating to deficits in executive function and working memory. These impairments can have a significant effect on day-to-day functioning, preventing an individual from being able to continue employment, maintain relationships and live independently (Andreassen et al., 2023). Additionally, impairments in dopamine regulation in the prefrontal cortex are supposed to impact neurotransmitter imbalance in the disorder, specifically an increased dopamine activity in the mesolimbic pathway and increased dopamine activity elsewhere in the body.
Dysfunction of the prefrontal cortex also affects emotional regulation, including blunted affect, social withdrawal, and difficulty interpreting emotional cues (Hinostroza & Mahr, 2024). These symptoms can often lead to isolation and suppression of the quality of life by inhibiting individuals’ ability to engage in social interaction. Cognitive and emotional dysfunction combine to form a complex clinical picture that can vary from one individual to another (Dabiri et al., 2022).
The second implication of prefrontal dysfunction in schizophrenia is its effect on insight and judgement (Blay et al., 2021). For many people who have schizophrenia, detecting their symptoms and finding reasons to seek treatment can be pretty tricky. What is thought to be caused by an inability to monitor the self something that depends on prefrontal networks — is this lack of insight, which is called anosognosia. This, therefore, can result in poor treatment adherence, thus frequent relapses and hospitalisation. A framework derived for understanding the role of the prefrontal cortex in schizophrenia is helpful for both diagnosis and intervention (Friedman & Robbins, 2021). It underscores the fact that relief of cognitive symptoms, which tend to be more resistant to conventional antipsychotics but are key to recovery and the social integration, should be an important therapeutic goal.
Effective treatment programmes for schizophrenia involving a dual approach, including pharmacological and psychosocial interventions, should target cognitive and emotional dysfunction associated with the prefrontal cortex, as discussed in 6009PY Clinical Neuroscience (Solmi et al., 2022). Treatment is typically pharmacological, with the starting drug being an antipsychotic that aims to restore dopamine balance. Although these treatments are usually helpful in controlling positive symptoms such as hallucinations and delusions, they have little effect on the cognitive impairment problem linked to prefrontal dysfunction (Friedman & Robbins, 2021). Usually, second-generation antipsychotics are preferred because they are believed to have a more balanced effect on dopamine in different parts of the brain. However, medication is generally insufficient to restore function (Solmi et al., 2022).
However, Cognitive Remediation Therapy (CRT) could be introduced to address the cognitive symptoms more directly. CRT is a structured, evidence-based intervention to improve specific cognitive functions such as memory, attention, and problem-solving (Barron & Storch, 2021). This therapy uses the engagement of neural networks in the pre-frontal cortex to aid in strengthening executive functioning and improving performance on tasks of everyday living. Cognitive improvements are associated with improved education, employment, and independent living. Psychosocial support is also vital (Reynolds et al., 2022). Supported employment, social skills training, and group therapy are programs that give a structure to people whereby they can practice new cognitive and emotional regulation strategies. They help in community integration and reduce the risk of relapse (Sprague et al., 2019).
However, family psychoeducation may prove helpful in helping with treatment adherence as well. Caregivers can educate on the prefrontal cortex, and this educates caregivers about the challenges of schizophrenia and leads to more empathetic and more informed at-home care (Harvey et al., 2018). However, treatment of schizophrenia that includes medication, cognitive rehabilitation and psychosocial support taken together remains the best chance of improving both symptom control and quality of life in those with schizophrenia (Kim et al., 2021).
Conclusion
The functional impairment of the PFC is tightly associated with schizophrenia, and the PFC is crucial for proper cognitive and behavioural functions. This essay mainly showed the PFC function in working memory, inhibitory control, decision-making, and emotional regulation of schizophrenia by cognitive deficits and emotional dysregulation. The clinical significance of this syndrome is underscored by structural and functional abnormalities in the PFC, namely, reduced grey matter volume and dopamine dysregulation. Improving patient outcomes requires evidence-based treatments targeting these dysfunctions, such as pharmacological interventions or cognitive therapies. Future research should address PFC-related deficits through innovative treatment. The ultimate goal of learning how the PFC works is to improve clinical neuroscience, develop more effective therapeutic approaches for disorders, and promise a better quality of life for those afflicted.
