Discover the Science of Health
This week is Brain Awareness Week (BAW), a worldwide week-long celebration of the brain. BAW was founded and is coordinated by the Dana Alliance for Brain Initiatives and European Dana Alliance for the Brain. Every year in March, BAW focuses on increasing public awareness about the progress and benefits of brain research.
Hearing voices that are not there was once thought to be a core symptom of schizophrenia and signify severe mental illness. It has been increasingly acknowledged that people with no other symptoms of schizophrenia or psychosis do hear voices [1]. There are several theories about what causes these auditory hallucinations. For example, there is good evidence that hearing voices can be linked to trauma [2]. Attempting to understand the phenomenon is not only scientifically interesting but also relates to how society views people with these experiences and if and how they may be treated. A search for how these experiences are associated with brain function is ongoing. New research published in the journal Human Brain Mapping suggests that the predisposition to hearing voices may relate to abnormal functioning of the brain whilst at rest [3].
This week is Brain Awareness Week (BAW), an annual observance dedicated to raising public awareness about the progress and benefits of brain research. Coordinated by the Dana Alliance for Brain Initiatives and the European Dana Alliance for the Brain, every March, BAW unites the efforts of partner organizations around the world in a week-long celebration of the brain.
From visiting classrooms for Brain Awareness Week, Dr. Janet Dubinsky from the Department of Neuroscience at the University of Minnesota became aware that teachers wanted to learn what neuroscience has uncovered about brain mechanisms of learning and memory. To address this need, the Department of Neuroscience and the Science Museum of Minnesota created BrainU. Her current partner is Dr. Gillian Roerhig from the STEM Education Center.
Launched in 2000, BrainU is a grant-funded professional development program that teaches educators neuroscience principles and effective methodology for teaching neuroscience in the middle to high school classroom. BrainU, the neuroscience teacher institute, provides teachers with up to 160 hours of neuroscience training, materials, and staff support to bring brain science to their students. Participants in these professional workshops receive updates on the latest in neuroscience research — discussion is complemented with hands-on activities and lab work.
The BrainU website provides lesson plans and resources for teachers and some cool stuff, including brain pictures, optical illusions, and movies.
In the nervous system, the synapse is essential for neuronal function. A synapse is the junction between two nerve cells or neurons, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter. The movie ‘The Synapse’, used with permission from BrainU, tells an entertaining and informative story of how neurons communicate with each other at synapses, changing information from electrical to chemical and back to electrical signals. Check out their story below (the movie opens in a new window).

Bipolar Disorder, also known as manic–depressive disorder, is a condition characterized by alternating states of elevated energy, cognition and mood, with periods of irritable mood and depression. The extreme mood swings experienced by patients with bipolar disorder have been strongly associated with disruptions in circadian rhythms — the 24-hour cycle of biological processes that govern our day and night activity.
Lithium is one of the most common treatments for bipolar disorder. However, little research has been done to find out if and how lithium impacts the brain and peripheral body clockwork. A new study published in the open access journal PLoS ONE reveals a novel link between lithium, bipolar disorder and circadian rhythms [1].
