Lesson 4 • Somatosensory Pathways

Traces touch, pain, and proprioception signals from periphery to cortex. Introduces the concept of topographic mapping in sensory processing.

Lesson 1 • Memory Systems and Classification

Distinguishes declarative, procedural, working, and episodic memory systems. Maps each type to its primary neural substrate.

Lesson 2 • Forgetting and Memory Failure

Explains interference, decay, retrieval failure, and motivated forgetting. Grounds learners in the limits of memory for practical application.

Lesson 3 • Synaptic Plasticity Mechanisms

Covers long-term potentiation, long-term depression, and NMDA receptor roles. Provides the molecular basis for learning at the synapse.

Lesson 4 • Neuroplasticity Across the Lifespan

Contrasts critical periods, adult plasticity, and experience-dependent remodeling. Connects plasticity concepts to rehabilitation and skill training.

Lesson 1 • Limbic Circuit Architecture

Maps the amygdala, hippocampus, cingulate cortex, and their interconnections. Extends the limbic anatomy introduced in Chapter 1 to functional networks.

Lesson 2 • Stress Response and the HPA Axis

Explains hypothalamic-pituitary-adrenal axis activation and cortisol effects on the brain. Links hypothalamic functions from Chapter 1 to emotional regulation.

Lesson 3 • Emotional Regulation Strategies

Covers prefrontal inhibition of amygdala, cognitive reappraisal, and top-down control. Bridges neuroscience to practical emotional management skills.

Lesson 4 • Reward, Motivation, and Dopamine

Analyzes the mesolimbic dopamine system and its role in reward prediction and motivation. Connects dopaminergic pathways from Chapter 2 to goal-directed behavior.

Lesson 1 • Prefrontal Cortex Subdivisions

Distinguishes dorsolateral, ventromedial, and orbitofrontal regions by function. Provides the anatomical specificity needed for executive function analysis.

Lesson 2 • Decision-Making and Risk Assessment

Covers somatic marker hypothesis, value-based choice, and risk evaluation circuits. Connects emotional valuation from Chapter 5 to rational decision processes.

Lesson 3 • Inhibitory Control and Flexibility

Details response inhibition, task switching, and cognitive flexibility mechanisms. Shows how control processes prevent impulsive and habitual errors.

Lesson 4 • Working Memory and Cognitive Control

Examines how the prefrontal cortex maintains and manipulates information online. Extends working memory concepts from Chapter 4 to executive control.

Lesson 1 • Circadian Rhythm and Sleep Regulation

Explains the suprachiasmatic nucleus, melatonin signaling, and homeostatic sleep pressure. Connects hypothalamic regulation from Chapter 1 to daily rhythms.

Lesson 2 • Consciousness and Neural Correlates

Introduces global workspace theory, default mode network, and levels of consciousness. Synthesizes cortical and subcortical systems into a unified awareness model.

Lesson 3 • Sleep and Cognitive Function

Analyzes how sleep deprivation impairs attention, memory, and executive function. Reinforces memory consolidation concepts from Chapter 4.

Lesson 4 • Sleep Stages and Architecture

Describes NREM stages, REM sleep, and the ultradian cycle across a night. Provides the structural framework for understanding sleep's cognitive functions.

Lesson 1 • Psychiatric Disorders and Neural Circuits

Analyzes depression, anxiety, schizophrenia, and ADHD through circuit-level models. Integrates neurotransmitter and prefrontal knowledge from Chapters 2 and 6.
