Cognitive Neuroscience
Cognitive neuroscience is the scientific field that studies the biological processes that underlie cognition. These processes include perception, attention, language, memory, decision-making, problem-solving, and emotion. Cognitive neuroscience is a relatively new field, with most of the research being conducted in the last 50 years. However, it has already made significant contributions to our understanding of the mind and brain.
History of Cognitive Neuroscience
The history of cognitive neuroscience can be traced back to the early 19th century, when scientists began to study the effects of brain damage on cognition. In the 1860s, French neurologist Paul Broca discovered that damage to a specific area of the brain, now known as Broca's area, caused difficulty with speech production. This discovery led to the understanding that different areas of the brain are responsible for different cognitive functions.
In the early 20th century, scientists began to use new technologies, such as electroencephalography (EEG) and magnetic resonance imaging (MRI), to study the brain. These technologies allowed scientists to visualize brain activity and to better understand the relationship between brain activity and cognition.
In the 1950s and 1960s, cognitive psychologists began to develop new theories about how the mind works. These theories, which were based on the idea that the mind is a computational system, led to a new wave of research in cognitive neuroscience.
In the 1970s and 1980s, cognitive neuroscientists began to use new technologies, such as functional magnetic resonance imaging (fMRI) and positron emission tomography (PET), to study the brain. These technologies allowed scientists to visualize brain activity in real time and to better understand how different brain regions work together to support cognition.
Methods of Cognitive Neuroscience
Cognitive neuroscientists use a variety of methods to study the brain and cognition. These methods include:
