Cognitive Neuroscience is a branch of Neuroscience, which is concerned with the scientific studies of neural network and its mechanisms underlying cognition. It has a special focus on the neural network and their connections within the brain which are involved in mental processes.
Sometimes Cognitive Neuroscience overlaps with cognitive psychology. The method used in Cognitive Neuroscience includes the experimental procedures from cognitive psychology, psychophysics, affective Neuroscience, functional neuroimaging, behavioural genetics, and cognitive genomics.
Cognitive Neuroscience combines the computational neuroscience modelling and cognitive psychology to give birth to new theories about the brain. It is an emerging field of Neuroscience in which we are trying to control the functioning of our brain by studying the behaviour of the brain.
