Introduction

The study of the neurological underpinnings of mental processes is known as cognitive neuroscience. It intersects with physiological psychology, cognitive psychology, and neuropsychology, and is at the interface of psychology and neuroscience. It integrates cognitive psychology theories and computational modelling with brain-related experimental data.

Description

The study of the biological processes and properties that support cognition is the focus of cognitive neuroscience, with a special emphasis on the neural connections in the brain that are involved in mental processes. It investigates how the brains neural networks influence or control cognitive tasks. Cognitive neuroscience is a branch of neuroscience and psychology that includes behavioural neuroscience, cognitive psychology, physiological psychology, and affective neuroscience, among other disciplines. Cognitive neuroscience is a discipline of psychology that integrates cognitive science concepts with neurobiological data and computer modelling to produce new insights. Cognitive neuroscience is the study of cognitive function deriving from the physical and chemical activity of neurons in the brain. Learning and memory are mostly reliant on the change of connections, which occurs through the propagation of activity via excitatory and inhibitory connections. Some studies say that specific brain areas carry out independent, limited processing tasks, while others argue that each region contributes to a dispersed, interactive process in its own unique way [1-4].

Several areas of the brain play an important role in this discipline. Because the primary goal is to develop a neuronal understanding of cognition, neurons, together with the various lobes of the cerebral cortex, play the most significant role. Cognitive neuroscience employs experimental methods from psychophysics and cognitive psychology, as well as functional neuroimaging, electrophysiology, cognitive genomics, and behavioural genetics. Patients with brain injuries who have cognitive impairments are an important element of cognitive neuroscience study. Damages in lesioned brains provide a comparable starting point in terms of healthy and completely functioning brains. The brain's neural networks are disrupted by these lesions, causing it to malfunction during basic cognitive activities like memory and learning. We may assess how healthy brain networks function in the presence of such damage and derive inferences about the basis of the impacted cognitive processes [5].

Furthermore, developmental cognitive neuroscience is a subset of cognitive neuroscience that explores and investigates cognitive abilities as they develop in the brain. This graph displays brain growth through time, allowing for comparison and speculation about possible reasons. Cognitive neuroscience is a multidisciplinary field of study that brings together neuroscience and psychology. There were several stages in these disciplines that changed the way academics viewed their study, eventually leading to the full formation of the area [6,7].

Conclusion

Although the goal of cognitive neuroscience is to understand the neural mechanisms that govern the mind, it has historically focused on how a certain area of the brain supports a particular mental faculty. Early attempts to subdivide the brain, however, were unsuccessful. The phrenologist movement was dismissed after failing to provide a scientific basis for its claims. Brain mapping, which began with Hitzig and Fritsch's experiments and eventually developed through methods such as Positron Emission Tomography (PET) and functional magnetic resonance imaging, also rejected the aggregate field view, which stated that all areas of the brain were involved in all behaviour (fMRI). The cognitive revolution, Gestalt theory, and neuropsychology were important turning points in the development of cognitive neuroscience as a field, bringing together concepts and methodologies that allowed researchers to discover more connections between behaviour and its brain underpinnings.
