Hesselink, MD, FACR MR imaging is exquisitely sensitive for detecting brain abnormalities. Particularly in the evaluation of white matter diseases, MR far outperforms any other imaging technique. Lesions that may be quite subtle or even invisible on CT are often clearly seen on the MR scan. Stress, Depression, Anxiety, Drug Use. Kim Peek: The Real Rain Man. Kim Peek, the genius who inspired Dustin Hoffman's character in Rain Man, has died from a heart attack at the age of 58.
Kim Peek was classed as a mega-savant and had memorized 12,000 books, including the entire Bible, but had difficulty with ordinary tasks like getting dressed and combing his hair. His astonishing abilities included being able to read one page of a book with his left eye and the other with his right. It took him just eight seconds to read and remember a page.
Daniel Tammet - The Boy With The Incredible Brain. How do things look? Many people mistakenly think anyone labeled as "colorblind" only sees black and white - like a black and white movie or television show.
On the contrary, it is extremely rare to have monochromacy - the complete absence of any color sensation. The variations in type and severity of colorblindness are explored in more detail in the section Colorblindness. Anomalous trichromacy (where vision is based on three functioning cone types, but one or more cone types are atypical) is by far the most common form of colorblindness, and in many senses it is the least severe.
Its effect is to reduce the ability to discriminate between colors, but it does not eliminate color perception altogether. People with this form of colorblindness experience very little difficulty in doing tasks that require color vision. Dichromats (those with vision based on two functioning cone types) on the other hand, can be so severely color deficient as to affect their daily lives. Psychoneuroimmunology of Depression. Back to Psychopharmacology - The Fourth Generation of Progress Psychoneuroimmunology of Depression Michael Irwin The central nervous system is hypothesized to have a role in the modulation of immune function.
This chapter provides an overview of the association between psychological factors and immunity, concentrating on the immunological alterations of depression. In addition, experimental evidence is reviewed of the neural and endocrine mechanisms that have been proposed to alter immune function in depression. The immune system functions to discriminate "self" from "nonself" cells, protecting the organism from invasion by pathogens, such as viruses and bacteria, or from abnormal internal cells such as cancer cells.
Psychoneuroimmunology. A Harvard study in the seventies discovered receptors on our immune cells for neuropeptides.
Neuropeptides are chemicals produced by the brain that vary with our emotions. The results of this study point to the simple fact that your immune system is listening to your mental talk.

Alzheimer’s Colombia. At frighteningly young ages, in their 40s, four of Laura Cuartas’s children began forgetting and falling apart, assaulted by what people here have long called La Bobera, the foolishness.
GPCOG Dementia test. Cognitive fun! Expand Your Mind. To expand your mind you need to learn new facts and develop new modes of thinking that will make the information that you already know more useful.
Solving the following problems requires a combination of world knowledge, mathematics, common sense, logic, and science (chemistry, physics). This is not an IQ test. There is no time limit. To expand your mind, do not look at the answers until after you have made an honest effort to figure out the problems. The Bear A bear walks south for one kilometer, then it walks west for one kilometer, then it walks north for one kilometer and ends up at the same point from which it started. The Chicken and Egg Problem A chicken farmer has figured out that a hen and a half can lay an egg and a half in a day and a half.
The Chicken and Leg Problem A chicken farmer also has some cows for a total of 30 animals, and the animals have 74 legs in all. Perception puzzles. This page illustrates that our visual perception cannot always be trusted.
The components of an object can distort the perception of the complete object. Our mind is the final arbiter of truth. Most optical illusions are the result of 1) incongruent design elements at opposite ends of parallel lines, 2) influence of background patterns on the overall design, 3) adjustment of our perception at the boundaries of areas of high contrast, 4) afterimages resulting from eye movements or from kinetic displays, or 5) inability to interpret the spatial structure of an object from the context provided by the picture. The Parthenon Optical illusions have been studied for millenia. Perpetually ascending staircase. Assesment, IQ and Aptitude Test. Aspie-quiz. Memory Loss Supplements.
