Ramachandran on your mind

Vilayanur Ramachandran tells us what brain damage can reveal about the connection between celebral tissue and the mind, using three startling delusions as examples. http://www.ted.com

“Understanding Biological Psychology is really biology for psychology rather than a watered-down biology text. Its great strength is bridge building across the many areas of psychology. As a geneticist, I especially appreciated the way the book integrates the latest genetic advances, something seldom seen in biological psychology textbooks” Robert Plomin, Institute of Psychiatry, London.

“Here is a textbook writer who encourages students to reflect on wider implications of research findings.” The Psychologist

Neurologist and author Oliver Sacks brings our attention to Charles Bonnett syndrome — when visually impaired people experience lucid hallucinations. He describes the experiences of his patients in heartwarming detail and walks us through the biology of this under-reported phenomenon.

Methamphetamine is one of the hardest drugs to quit. Its abuse is ravaging rural communities and cities alike. NGC correspondent Lisa Ling goes inside this global epidemic to find out what makes meth so addictive and destructive.

Experiments in animals idetified areas of the brain thet seemd to induce a pleasurable state.
If an animal was trained to press a lever to recieve brain stimulation in these areas, they would choose to bar press over the food, water, or sex.

Such animals will self-stimulate till exhaustion! (this experiment has relevance to human addiction)





What is rewarding brain stimulation?




Pleasure Systems in the Brain
(Michael A. Bozarth)

… Olds and Milner (1954) first identified brain sites where direct electrical stimulation is reinforcing. Laboratory animals will lever press at high rates (> 6,000 times per hour) to obtain brief stimulation pulses to certain brain regions. The reinforcement from direct electrical activation of this reward substrate is more potent than other rewards, such as food or water. The potency of this electrical stimulation is most dramatically illustrated in a classic experiment where the subjects suffered self-imposed starvation when forced to make a choice between obtaining food and water or electrical brain stimulation (Routtenberg & Lindy, 1965). A second distinguishing feature of reward from electrical brain stimulation is the lack of satiation; animals generally respond continuously, taking only brief breaks from lever pressing to obtain the electrical stimulation. These two features (i.e., super-potent reward and lack of satiation) are important characteristics of direct activation of brain reward mechanisms… (full article)

Understanding the Brain
Taught By Professor Jeanette Norden, Ph.D., Vanderbilt University School of Medicine, Vanderbilt University

This series of lectures is ONE OF THE BEST WAYS TO START of learning about the ever-so-amazing brain!
Understanding the Brain provides you with an in-depth view of the inner workings of your brain. Your tour starts with the organization of the central nervous system at the gross, cellular, and molecular levels, then investigates in detail how the brain accomplishes a host of tasks—from seeing and sleeping to performing music and constructing a personal identity.
