After providing all the funding for The Brain from Top to Bottom for over 10 years, the CIHR Institute of Neurosciences, Mental Health and Addiction informed us that because of budget cuts, they were going to be forced to stop sponsoring us as of March 31st, 2013.

We have approached a number of organizations, all of which have recognized the value of our work. But we have not managed to find the funding we need. We must therefore ask our readers for donations so that we can continue updating and adding new content to The Brain from Top to Bottom web site and blog.

Please, rest assured that we are doing our utmost to continue our mission of providing the general public with the best possible information about the brain and neuroscience in the original spirit of the Internet: the desire to share information free of charge and with no adverstising.

Whether your support is moral, financial, or both, thank you from the bottom of our hearts!

Bluffing in Interrogations Leads to False Confessions

When someone who was suspected of a crime confessed to it, that always used to be regarded as convincing evidence of his or her guilt. But with the advent of molecular biology, traces of DNA have been used to prove the innocence of many suspects, some 25% of whom had previously pleaded guilty or signed confessions after being interrogated.

How is this possible? The psychologists who study this question distinguish two main categories of factors that can lead suspects to incriminate themselves in this way. The first category consists of personal vulnerabilities, such as being young, or intellectually impaired, or having a compliant personality. The second consists of pressures inherent in the conditions of custody and interrogation, such as having an insufficient knowledge of the law, or being afraid of being assaulted, or threatened with a severe sentence, or subjected to torture that causes pain.

When Fear Makes Us React Conservatively

Paul Nail and his colleagues at the University of Central Arkansas conducted a series of three experiments that showed how a psychologically threatening situation can make someone whose thinking is usually liberal adopt a more conservative position. The adjectives “liberal” and “conservative” should be understood here in their general sense, where the former describes an attitude favouring openness, empathy, communication, and social justice, while the latter emphasizes tradition, order, authority, and discipline.

The subject this week is the sub-topic “Forgetting and Amnesia” under the topic “Memory and the Brain”. For each link, I also provide a brief description of the content on the site in question.

Eight Problems with Mirror Neurons

Mirror neurons are neurons with fascinating characteristics that were discovered in monkeys in the mid-1990s. Located mainly in Area F5 of the cortex, these neurons are activated not only when a monkey performs a specific action but also when that monkey simply sees another monkey perform that same action. This is surprising behaviour, to say the least, for neurons located in a motor area of the cortex.

Since just about the same area (the premotor area) exists in the human brain, it is highly likely that humans also have mirror neurons. But the data that have been gathered on this subject remain controversial, because of constraints on experiments with human beings. (more…)
