This work is for upper-level undergraduates, academics and professionals in neuropsychology, cognitive psychology, and neuroscience.;It identifies how excitory and inhibitory messages in the human nervous system combine and coordinate to affect attention, cognition, memory, and language. Communication within the nervous systems involves the excitation and inhibition of neurons. How these processes interact to affect cognition and behavioral performance has been an area of ongoing investigation that is once again at the forefront of cognitive research. This volume brings together cognitive psychologists and neuroscientists to identify the neural evidence for inhibitory mechanisms in cognitive processing and discusses how these inhibitory mechanisms subsequently affect cognition and behavior.
