The evolution of human memory

By Elisabeth A. Murray, Steven P. Wise, and Kim S. Graham

Like all biological traits, human memory reflects a long evolutionary history, most of it shared with other animals. Yet, with rare exceptions, evolution has either been overlooked in discussions of memory or treated in an outdated way. As a result, a simple idea about the cerebral cortex has reigned for more than a century: that its various areas specialize in functions characterized as memory, perception, the control of movement, or executive control (mainly decision-making).

Where to eat in San Diego during SfN 2016

By Craig Panner

In just a few days, the Society for Neuroscience annual meeting will be kicking off in San Diego, California. I’ve had a number of homes in my 48 years; the most recent being the New York/New Jersey area for the last ten years as part of Oxford University Press. But the longest home, and the one I keep coming back to, is San Diego. The weather is perfect, the multi-cultural facets are inspiring, the local universities top-notch, and the food scene is divine.

Getting to know your cerebellar self

By John Montgomery and David Bodznick

The cerebellum is an intriguing part of our brain. Its name is the diminutive form of cerebrum, so literally means ‘little brain’. It is true that, in humans, it occupies just 10% of the brain volume, yet recent research shows it accounts for approximately 80% of the nerve cells; a complex network of approximately 69 billion neurons! Why does the ‘little brain’ contain such a disproportionate number of neurons?

Treatment of depression in autism spectrum disorder

By Christopher J. McDougle

Mood disorders, including major depressive disorder, appear to be more common in those with developmental disorders, including autism spectrum disorder (ASD) than in the general population. However, diagnosing depression in ASD represents a challenge that dates back to Leo Kanner’s original description of “infantile autism” in 1943. Kanner described a disturbance of “affective contact” in those with autism.

How much choice is there in addiction?

By Nick Heather and Gabriel Segal

There is much that we agree about in our understanding of addiction and what can be done about the harm it causes. However, unusually perhaps for collaborators, we disagree about some important implications of suggesting a rethink of the relationship between addiction and choice. First, what do we agree on? We agree that the relationship between addiction and choice needs rethinking.

Becoming better strategic thinkers

By Arnaud Chevallier

A manager at a hotel receives an alarming number of complaints from her guests that they have to wait too long for elevators. So she requests quotes for installing an additional elevator. Turned down by the price tag of that solution, the manager seeks an alternative and decides to give her guests something to do while they wait for the elevator, by installing mirrors or televisions or providing magazines.

Is happiness in our genes?

By Michael Pluess

It is easy to observe that some people are happier than others. But trying to explain why people differ in their happiness is quite a different story. Is our happiness the result of how well things are going for us or does it simply reflect our personality? Of course, the discussion on the exact roles of nature (gene) versus nurture (experience) is not new at all. When it comes to how we feel, however, most of us may think that our happiness

The impact of addictions and means of prevention, treatment, & recovery

By Cassandra Gill

September is National Recovery Month in the US. Recovery Month is a time dedicated to increasing awareness and understanding of substance use and mental disorders. It’s also a time to celebrate those who are in recovery and those who do recover. The goal of the observance month is to educate others that addiction treatment and mental health services are effective, and that people can recover. With respect for this time, we compiled some statistics on addiction disorders to support awareness of these issues and show that individuals are not alone.

Genome editing’s brave new world

By John Parrington

“O, wonder!/How many goodly creatures are there here!/How beauteous mankind is!/O brave new world,/That has such people in’t!” Shakespeare’s lines in The Tempest famously inspired Aldous Huxley’s novel Brave New World, first published in 1932. Huxley’s vision of the future has become a byword for the idea that attempts at genetic (and social) engineering are bound to go wrong. With its crude partitioning of society, by stunting human development before birth, and with its use of a drug – soma – to induce a false sense of happiness and suppress dissent, this was the opposite of a ‘beauteous’ world.

Why peer review is so important

As part of Peer Review Week, running from 19-25 September 2016, we are celebrating the essential role that peer review plays in maintaining scientific quality. We asked some of our journal’s editorial teams to tell us why peer review is so important to them and their journals.

What has functional brain imaging discovered?

By Richard Passingham

Functional magnetic brain imaging (fMRI) is a method that allows us to study the workings of the human brain while people perceive, reason and make decisions. The principle on which it is based is that, when nerve cells or neurons in a particular region become active, there is an increase in the blood supply to that brain area. This can be visualized because the scanner can be sensitized to the changes in the blood oxygen level that occur when the nerve cells become active.

Influencing social policy in the public interest

By Kenneth I. Maton

How can psychologists and other social scientists interested in making a difference become more fully and effectively engaged in the policy world? To address this question, in-depth interviews were conducted with 79 psychologists who were asked to describe their policy experiences over the course of their careers, with particular focus on a major policy success.

Science, sincerity, and transformation of near-death experiences

By Benjamin Mitchell-Yellin

One of the first great philosophical books, Plato’s Republic, concludes with the recounting of a near-death experience. Socrates relates the myth of Er, a soldier who died in battle but came back to tell what he saw in the other world. Like other myths in Plato’s works, this is meant to supplement Socrates’ philosophical arguments and to help instill noble beliefs. It’s a last ditch effort at making the case for living a just life.

The impact of suicide: World Suicide Prevention Day and why suicide awareness matters

By Julie Cerel and Rebecca L. Sanford

Each year over one million people worldwide die by suicide. In the United States, approximately 42,000 people die by suicide each year, with a suicide occurring every 12.3 minutes. It is the 10th leading cause of death overall, and the 2nd leading cause of death for youth under the age of 24. For World Suicide Prevention Day, we’d like to tell you why this matters to us and why it should matter to you.

Hypnosis and the conscious awareness of intentions

By Peter Lush and Zoltan Dienes

A hypnotist tells a subject that their outstretched arm will begin to rise upward as though tied to an invisible balloon. To their astonishment, the subject’s arm rises just as suggested, and seemingly without their intention. While it may appear as though the subject is being controlled by the hypnotist, it is well established that nobody can be hypnotised against their will. Hypnosis therefore seems to present a paradox

A new (musical) direction for healthcare?

By Kimberly Sena Moore

Most would agree with the idea that music can have a powerful hold over us—our thoughts, feelings, and movements. Given this, how might music help measure thoughts, feelings, and movements in a way that allows professionals in healthcare improve client treatment? The music therapy profession seems to be experiencing a surge in developing data-measuring tools that incorporate music in the client assessment.
