Brain Function Course

Lesson 1 • Ventricular System and Cerebrospinal Fluid

Describes the four ventricles and cerebrospinal fluid circulation. Explains how fluid dynamics protect and nourish the brain.

Lesson 2 • Cerebral Cortex and Lobes

Maps the four cortical lobes and their primary functional zones. Connects surface anatomy to sensory, motor, and cognitive processing.

Lesson 3 • Subcortical Structures

Examines structures beneath the cortex, including the basal ganglia, thalamus, and hypothalamus. Links each structure to specific regulatory and relay functions.

Lesson 4 • Brainstem and Cerebellum

Details the midbrain, pons, medulla, and cerebellum as controllers of vital and motor functions. Grounds learners in life-sustaining neural architecture.

Lesson 1 • Major Neurotransmitter Systems

Surveys dopamine, serotonin, glutamate, GABA, and acetylcholine pathways. Links each system to specific behavioural and cognitive functions.

Lesson 2 • Synaptic Transmission

Details chemical and electrical synapses, neurotransmitter release, and receptor binding. Connects cellular events to network-level communication.

Lesson 3 • Neuron Structure and Types

Covers the morphology of neurons and major classification schemes. Establishes the cellular basis for all brain signalling discussed later.

Lesson 4 • Glial Cells and Support Functions

Identifies astrocytes, oligodendrocytes, microglia, and their roles. Shows how non-neuronal cells maintain brain health and modulate signalling.

Lesson 1 • Basal Ganglia and Movement Modulation

Explains direct and indirect pathways that refine motor output. Connects basal ganglia dysfunction to movement disorders introduced later.

Lesson 2 • Motor Cortex and Voluntary Movement

Covers primary motor cortex organisation, corticospinal tract, and motor unit recruitment. Establishes the cortical origin of voluntary movement commands.

Lesson 3 • Cerebellar Motor Coordination

Details how the cerebellum compares intended and actual movement to correct errors. Reinforces the cerebellum's role introduced in Chapter 1.

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 remodelling. 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

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

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 signalling, 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. Synthesises cortical and subcortical systems into a unified awareness model.

Lesson 3 • Sleep and Cognitive Function

Analyses 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

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

Lesson 2 • Principles of Neurorehabilitation

Applies plasticity, motor learning, and cognitive training principles to rehabilitation design. Synthesises knowledge from Chapters 3, 4, and 5 into clinical practice.

Lesson 3 • Stroke and Traumatic Brain Injury

Covers ischaemic and haemorrhagic stroke, diffuse axonal injury, and recovery trajectories. Applies vascular anatomy and plasticity principles from earlier chapters.

Lesson 4 • Epilepsy and Abnormal Excitability

Explains seizure generation, propagation, and classification based on excitatory-inhibitory imbalance. Builds on action potential and neurotransmitter concepts.
