Finding Your Way Through the BrainV. And Overview of Brain Function and StructureVI. Surface FeaturesOutline of Current Lecture II. Two Main Types of CellsIII. The Brain’s Internal FeaturesIV. The Central Nervous System: Mediating BehaviorCurrent LectureTwo Main Types of Cells- Neurons- Glial cellsThe Brain’s Internal Features- Nucleus- Nerve- TractThe Central Nervous System: Mediating BehaviorThree Major Components- Spinal cord- Brainstem- ForebrainThe Spinal Cord- Controls most body movements- Can act independently of brainThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- Spinal reflex: example of how spines can act independently of braino Automatic movemento Hard to prevent (brain can’t inhibit)o Ex: Knee jerkThe Brainstem- Begins where the spinal cord enters the skull- Produces movement and creates sensory world- The regions: (all developed as simple animals evolved brains)o Hindbraino Midbraino Diencephalon- Hindbrain: evolutionarily the oldest parto Contains: cerebellum, reticular formation, pons, medulla- Midbraino Tectumo Tegmentum- Diencephalono Hypothalamuso Thalamus- The Forebraino Neocortexo Basal ganglia Caudate nucleus, putamen, and global palliduso Limbic system Amygdala, hippocampus, and cingulate cortexo Cortical layers Cytoarchitectonic
