Seeing with the Brain: Hallucinations, a New Book by Oliver Sacks
November 20, 2012
, a new book by Oliver Sacks, MD, hit store shelves (and e-readers) this month, and—like many of his other books—it is sparking conversations not only in the scientific community but also more widely among the reading public.
Sacks is a clinical neurologist and professor at New York University School of Medicine. He is best known for his books that examine case studies from his own research and practice, including
The Mind’s Eye, Musicophilia
The Man Who Mistook His Wife for a Hat
(which inspired the 1990 feature film starring Robert De Niro and Robin Williams).
In this new book, Sacks asserts that, contrary to popular belief, hallucinations are not the sole purview of the mentally ill. In fact, they are surprisingly common among individuals with sensory deprivation (e.g., blindness) or medical conditions such as migraine, epilepsy, or Parkinson’s. Many healthy people experience hallucinations in the moments before sleep or upon waking, according to Sacks. Strong emotions associated with major life changes can trigger hallucinations, for example, when a bereaved spouse experiences a “visit” from his or her lost loved one. And of course, hallucinations can be a side effect of medication or intoxicants.
is a collection of fascinating stories, anecdotes, and case studies. Sacks describes a woman who hears not spoken voices, but music; a man who smells roast beef when he feels a migraine coming on; and a respected botanist who walks into his lab, only to see himself already at work. Drawing on history, art, religion, and popular culture, Sacks seeks to describe and better understand the experience of hallucination. As a clinician and researcher, he also delves into the biology of the brain and the neurological reasons behind many types of hallucinations.
With this book, Sacks hopes to ameliorate some of the stigma associated with hallucinations. In a recent
magazine, he said, “I think there’s a common view, often shared by doctors, that hallucinations denote madness—especially if there’s any hearing of voices. I hope I can defuse or de-stigmatize this a bit. This can be felt very much by patients. There was a remarkable study of elderly people with impaired vision, and it turned out that many had elaborate hallucinations, but very few acknowledged anything until they found a doctor whom they trusted.”
In a 2009 TED Talk entitled
“What Hallucination Reveals About Our Minds,”
Sacks provides an introduction to his subject, along with some background on the work that led to his recent book. The 20-minute TED Talk is available free online, so take a look—and let us know what you think. PAR wants to hear from you, so leave a comment and join the conversation!

New “children’s book” illustrates bedtime frustration with a dose of humor
The recent electronic release of Adam Mansbach’s “Go the F--- to Sleep” has taken the Web by storm. The book, which features as narrator a tired parent attempting to put his child to sleep for the night, combines mock-sweet prose with bursts of exasperation and annoyance. If you’re a parent, and you remember the sleepless nights—and you have a sense of humor—this amalgamation of genuine parental love with the eye-rolling that goes along with nighttime routines will probably strike a chord with you. The book and its release bring up several interesting issues, including the frustration experienced by all parents of young children. Ranging from mild annoyance to real anger, the feeling can be surprisingly overwhelming. Parenthood is generally advertised as a joyous walk through a meadow, and, for some, discovering that the meadow is filled with divots, bumblebees, and sharp branches is a shock. Though it could be said that the book uses strong language for shock value, for most readers, the use of expletives serves to highlight just how intense the aggravation can be. The book’s message goes a ...
Life with Bipolar Disorder through the Eyes of Dr. Mark Vonnegut
“The reason creativity and craziness go together is that if you’re just plain crazy without being able to sing or dance or write good poems, no one is going to want to have babies with you. Your genes will fall by the wayside. Who but a brazen crazy person would go one-on-one with blank paper or canvas armed with nothing but ideas?” Author Mark Vonnegut poses this question in the first chapter of his book, Just Like Someone Without Mental Illness Only More So. In this intimate and sometimes comic memoir, Vonnegut goes one-on-one with his past and present struggles with bipolar disorder, his family history, and his qualms with the medical field. His medical background and first-hand experiences provide readers with an eye-opening portrayal of life with mental illness. In order to understand his own disorder, Vonnegut looks at his family’s history as far back as his paternal great-grandfather. He ventures into his childhood, endearingly poking fun at his not-yet-famous father’s eccentricities and struggles as “the world’s worst car salesman who couldn’t get a job teaching English at Cape Cod ...
The reviews are in for the SDS Handbook!
If you haven’t added the Handbook for Using the Self-Directed Search®: Integrating RIASEC and CIP Theories in Practice by Robert C. Reardon, PhD, and Janet G. Lenz, PhD, to your career assessment library, there is no better time than now!

We Are All People With Ability
In 1987, Ronald Reagan declared the month of March as National Disabilities Awareness Month. It serves as a formal time to recognize the efforts, struggles, and initiatives surrounding people with disabilities. In 1990, the Americans with Disabilities Act was passed, thus officially giving legal rights to those with disabilities regarding workplace discrimination. According to The Arc, whose mission is to protect the rights of human beings with intellectual and developmental disabilities, at least 4.6 million Americans have a disability. The Arc advocates in many ways for those with disabilities, including shaping public policy, providing services like employment programs and residential support, and preserving and protecting rights through education and activism. Triangle is a nonprofit organization in Malden, Massachusetts, that “empowers people with disabilities to enjoy rich, fulfilling lives.” Together with the Accessible Icon Project, they are working to transform the original International Symbol of Access into something more visually representative of today’s individuals with disabilities. The new image conjures up words like “active, abled, engaged, ready for action, determined, and motivated…which helps provoke discussion on how we view disabilities and people ...
Brain-Based Assessment: An Interview with Steven G. Feifer (Part 2)
We recently sat down with Steven G. Feifer, DEd, author of the Feifer Assessment of Reading™ (FAR™) and Feifer Assessment of Mathematics™ (FAM™) for an interview to discuss how to use cognitive neuroscience to better understand why students struggle in school. This is the second part of a two-part interview. Did you miss Part 1? Catch up here. How do the FAR and FAM go beyond just using an aptitude/achievement discrepancy perspective? SF: The FAR and FAM represent a more ecologically valid way to understand the core psychological processes involved with both reading and mathematics. Many psychologists are used to measuring executive functioning, working memory, visual perception, and processing speed using stand-alone instruments, and then must clinically bridge these results into the worlds of reading and math. In other words, how does poor performance on executive functioning tasks impact the ability to read on grade level? These can be very difficult questions to answer. The FAR and the FAM seek to measure these psychological constructs while the student is actually engaged in the academic skill itself, allowing the examiner to directly determine ...
Individuals with Disabilities 286% More Likely to be a Victim of Violence
Adults with disabilities, particularly mental illness, have been found to be at an increased risk of being a victim of violence, according to a study funded by the World Health Organization’s Department of Violence and Injury Prevention and Disability. This finding, a meta-analysis of 21 studies, found that one in four people with a mental illness experience some type of violence in a given year – a much higher rate than that experienced by the general population. The chance that a person with a mental illness will experience physical, sexual, or domestic violence was found to be 3.86-fold higher than the odds of an adult without any disabilities at all. However, violence against individuals with other disabilities was common – it was found that individuals reporting any disability were 50 percent more likely to experience physical, sexual, or intimate partner violence in the prior 12 months than those individuals without a disability, and 60 percent higher for people with intellectual impairments. Researchers believe that their inclusion criteria probably underestimated the prevalence of violence against people with disabilities because many of the ...
