Parts of the Brain: Forebrain – Cerebral Cortex

In this video I continue explaining parts of the brain and focus on the cerebral cortex. The cortex is the thin, wrinkled, outer covering of the brain and the wrinkles and folds create gyri, sulci, and fissures. The cortex is … Read More

Parts of the Brain: Forebrain – Subcortical Structures

In this video I continue covering parts of the brain and move to the subcortical structures of the forebrain including the thalamus, pituitary gland, limbic system (hypothalamus, hippocampus, and amygdala), basal ganglia, and corpus callosum. I also mention the Genes … Read More

Parts of the Brain: Midbrain Structures

In this video I continue covering parts of the brain, explaining regions of the midbrain including the tegmentum, the substantia nigra, and the tectum. I also discuss the limitations of using 2D images when learning about brain structures, the use … Read More

Parts of the Brain: Hindbrain Structures

In this video I explain the main regions of the brain: the hindbrain, midbrain, and forebrain, as well as the difference between the “old” and “new” brain in evolutionary terms. Then the location and function of four main areas of … Read More

Brain Scanning and Imaging Techniques

In this video I briefly explain how information can be collected about the structure and function of a living brain using scanning and imaging techniques including EEG, CAT scan, PET scan, MRI, fMRI, and DTI. Don’t forget to subscribe to … Read More

A Textbook Problem: Prices, Pages, and Purpose

As we enter a new school semester, thousands of students will once again face the exorbitant prices of college textbooks. I’ve read a number of introductory psychology textbooks and while I love textbooks and have a deep appreciation for the … Read More

Early Ways of Studying the Brain

In this video I discuss early approaches to studying the brain by looking at cases of brain damage and attempting to connect areas of damage to deficits or changes in behavior. The case of Phineas Gage is considered, as well … Read More
