.Cognitive neuroscience is the scientific field that is concerned with the study of the processes and aspects that underlie, with a specific focus on the neural connections in the brain which are involved in. It addresses the questions of how cognitive activities are affected or controlled by neural circuits in the brain. Cognitive neuroscience is a branch of both and, overlapping with disciplines such as,. Cognitive neuroscience relies upon theories in coupled with evidence from, and.Parts of the brain play an important role in this field. Play the most vital role, since the main point is to establish an understanding of cognition from a neural perspective, along with the different lobes of the.Methods employed in cognitive neuroscience include experimental procedures from and, and.Studies of patients with cognitive deficits due to brain constitute an important aspect of cognitive neuroscience. The damages in lesioned brains provide a comparable basis with regards to healthy and fully functioning brains.These damages change the neural circuits in the brain and cause it to malfunction during basic cognitive processes, such as.

With the damage, we can compare how the healthy neural circuits are functioning, and possibly draw conclusions about the basis of the affected cognitive processes.Also, cognitive abilities based on brain development are studied and examined under the subfield of. This shows brain development over time, analyzing differences and concocting possible reasons for those differences.Theoretical approaches include. Timeline showing major developments in science that led to the emergence of the field cognitive neuroscience.Cognitive neuroscience is an interdisciplinary area of study that has emerged from. There were several stages in these disciplines that changed the way researchers approached their investigations and that led to the field becoming fully established.Although the task of cognitive neuroscience is to describe how the brain creates the mind, historically it has progressed by investigating how a certain area of the brain supports a given mental faculty. However, early efforts to subdivide the brain proved to be problematic.

The phrenologist movement failed to supply a scientific basis for its theories and has since been rejected. Main article:One of the predecessors to cognitive neuroscience was, a approach that claimed that behavior could be determined by the shape of the.

In the early 19th century, and believed that the human brain was localized into approximately 35 different sections. In his book, The Anatomy and Physiology of the Nervous System in General, and of the Brain in Particular, Gall claimed that a larger bump in one of these areas meant that that area of the brain was used more frequently by that person. This theory gained significant public attention, leading to the publication of phrenology journals and the creation of phrenometers, which measured the bumps on a human subject's head. While phrenology remained a fixture at fairs and carnivals, it did not enjoy wide acceptance within the scientific community. The major criticism of phrenology is that researchers were not able to test theories empirically. Localizationist view The localizationist view was concerned with mental abilities being localized to specific areas of the brain rather than on what the characteristics of the abilities were and how to measure them.

Studies performed in Europe, such as those of, supported this view. Jackson studied patients with, particularly those with.

He discovered that the epileptic patients often made the same and tonic movements of muscle during their seizures, leading Jackson to believe that they must be occurring in the same place every time. Jackson proposed that specific functions were localized to specific areas of the brain, which was critical to future understanding of the.Aggregate field view According to the aggregate field view, all areas of the brain participate in every mental function., a French experimental psychologist, challenged the localizationist view by using animal experiments. He discovered that removing the in rabbits and pigeons affected their sense of muscular coordination, and that all cognitive functions were disrupted in pigeons when the were removed. From this he concluded that the, and functioned together as a whole. His approach has been criticised on the basis that the tests were not sensitive enough to notice selective deficits had they been present. Emergence of neuropsychology Perhaps the first serious attempts to localize mental functions to specific locations in the brain was. This was mostly achieved by studying the effects of injuries to different parts of the brain on psychological functions.

In 1861, French neurologist Paul Broca came across a man who was able to understand language but unable to speak. The man could only produce the sound 'tan'. It was later discovered that the man had damage to an area of his left frontal lobe now known as. Carl Wernicke, a, found a patient who could speak fluently but non-sensibly. The patient had been the victim of a, and could not understand spoken or written language.

This patient had a lesion in the area where the left parietal and temporal lobes meet, now known as. These cases, which suggested that lesions caused specific behavioral changes, strongly supported the localizationist view.Mapping the brain In 1870, German physicians and published their findings about the behavior of animals. Hitzig and Fritsch ran an electric current through the cerebral cortex of a dog, causing different muscles to contract depending on which areas of the brain were electrically stimulated. This led to the proposition that individual functions are localized to specific areas of the brain rather than the cerebrum as a whole, as the aggregate field view suggests. Was also an important figure in brain mapping; his experiments based on Franz Nissl's tissue staining techniques divided the brain into fifty-two areas.20th century Cognitive revolution. Main article:At the start of the 20th century, attitudes in America were characterised by pragmatism, which led to a preference for as the primary approach in.

Was a key figure with his stimulus-response approach. By conducting experiments on animals he was aiming to be able to predict and control behaviour. Behaviourism eventually failed because it could not provide realistic psychology of human action and thought – it focused primarily on stimulus-response associations at the expense of explaining phenomena like thought and imagination. This led to what is often termed as the 'cognitive revolution'.
