Cognitive Neuroscience


Synopsis


Written by world-renowned researchers, including Michael Gazzaniga, Cognitive Neuroscience remains the gold standard in its field, showcasing the latest discoveries and clinical applications. In its new Fifth Edition, updated material is woven into the narrative of each chapter and featured in new Hot Science and Lessons from the Clinic sections. The presentation is also more accessible and focused as the result of Anatomical Orientation figures, Take-Home Message features, and streamlined chapter openers.

Summary

Chapter 1: Introduction to Cognitive Neuroscience

* Defines cognitive neuroscience as the study of the biological mechanisms underlying cognition.
* Emphasizes the interdisciplinary nature of the field, drawing from psychology, neuroscience, and computer science.
* Example: Magnetic resonance imaging (MRI) studies showing that brain regions involved in language processing are activated when people read words.

Chapter 2: Neural Basis of Sensation and Perception

* Explores how sensory organs transduce physical stimuli into neural signals.
* Discusses the role of specialized brain regions in processing different sensory modalities, such as vision and hearing.
* Example: Electroencephalography (EEG) recordings revealing distinct patterns of brain activity when people perceive different visual objects.

Chapter 3: Attention and Working Memory

* Investigates the neural mechanisms that enable selective attention and short-term memory.
* Highlights the role of the frontal cortex and parietal cortex in these cognitive processes.
* Example: Transcranial magnetic stimulation (TMS) studies showing that disrupting activity in the prefrontal cortex impairs working memory performance.

Chapter 4: Language and Memory

* Examines the neural basis of language comprehension, production, and memory.
* Describes the specialized brain regions involved in processing different aspects of language, such as semantics and syntax.
* Example: fMRI studies identifying the left inferior frontal gyrus as a key region for speech production and the left temporal lobe for semantic memory.

Chapter 5: Learning and Plasticity

* Explores the neural mechanisms underlying learning and memory formation.
* Focuses on the role of the hippocampus, amygdala, and prefrontal cortex in these processes.
* Example: Animal studies using electrophysiological recordings showing that neurons in the hippocampus encode new memories.

Chapter 6: Emotion and Motivation

* Investigates the neural basis of emotions, such as fear, anger, and happiness.
* Examines the role of the limbic system and neocortex in emotional processing and regulation.
* Example: fMRI studies revealing that activation in the amygdala is associated with feelings of fear.

Chapter 7: Decision-Making and Free Will

* Explores the neural mechanisms underlying decision-making and the concept of free will.
* Discusses the role of the prefrontal cortex, basal ganglia, and limbic system in these processes.
* Example: Single-unit recordings in monkeys showing that neurons in the prefrontal cortex represent the value of potential choices during decision-making.

Chapter 8: Consciousness and the Self

* Investigates the neural basis of consciousness and self-awareness.
* Examines the role of the frontal lobes, parietal lobes, and temporal lobes in these processes.
* Example: fMRI studies identifying a network of brain regions, including the prefrontal cortex and posterior parietal cortex, that are associated with self-referential processing.
