Cognitive Neuroscience is a field that explores how our brain processes information and influences our thoughts, feelings, and behaviors. It combines principles from psychology and neuroscience to understand how mental functions, like memory and decision-making, are linked to brain activity. Researchers use techniques like brain imaging to study how different areas of the brain, such as the prefrontal cortex and hippocampus, work together during various tasks. By examining the connections between brain structures and cognitive functions, scientists can gain insights into conditions like Alzheimer's disease and depression. This knowledge helps in developing better treatments and interventions, ultimately improving mental health and cognitive abilities in individuals.
