A visually compelling tour of the human brain, from anatomy to cells to genes and back.
How the brain works
This video attempts to explain the working of the brain through mapping out the electrical activity of the brain – Electro-encephalogram (EEG)
What effect does alcohol have on the brain?
In this video, students explore how neuroscientists design and carry out research on the effects of alcohol on the human brain. Specifically, it focuses on the hippocampus, a brain structure that is involved in memory and spatial navigation. Studies of adult brains have found that the hippocampus is particularly vulnerable to heavy alcohol use. In the e-lab, students address these research questions: “Does alcohol also affect younger brains? If so, does it affect them in the same way?”
From neurons to networks
Both a young child’s brain and our young, global Internet brain are in highly creative, experimental, innovative states of rapid development — just waiting to make connections. So, here’s a question for the 21st century: How do we help shape both of these young, rapidly growing networks to set a course for a better future? These were the questions that led filmmaker, Tiffany Shlainme, to make this short film.

Scientists have located a specific set of neurons that indicate how time passes, confirming that the brain plays an essential role in how we experience the passage of time.
Neuroscientists have found that by training on attention tests, people young and old can improve brain performance and multitasking skills.
A gene that is associated with regeneration of injured nerve cells has been identified by scientists at Penn State University and Duke University.
When given early treatment, children with autism spectrum disorders (ASD) made significant improvements in behavior, communication, and most strikingly, brain function, Yale School of Medicine researchers report in a new study.
Researchers have found some of the earliest signs of Alzheimer’s disease, more than two decades before the first symptoms usually appear.
Latest research on PTSD shows smaller brain area regulating fear response

Recent combat veterans who are diagnosed with post traumatic stress disorder have significantly smaller volume in an area of the brain critical for regulating fear and anxiety responses, according to research led by scientists at Duke University and the Durham VA Medical Center.
The finding, published Nov. 5, 2012, in the journal Archives of General Psychiatry, for the first time provides clear evidence that smaller amygdala volume is associated with PTSD, regardless of the severity of trauma. But it’s not clear whether the physiological difference was caused by a traumatic event, or whether PTSD develops more readily in people who naturally have smaller amygdalas.
Inside the unconscious brain
- The colored dots in this image represent locations of the electrodes used to measure brain activity. As the brain wave oscillations become more asynchronous relative to the position of the star, the colors fade from red to blue.

A new study from MIT and Massachusetts General Hospital (MGH) reveals, for the first time, what happens inside the brain as patients lose consciousness during anesthesia.
By monitoring brain activity as patients were given a common anesthetic, the researchers were able to identify a distinctive brain activity pattern that marked the loss of consciousness. This pattern, characterized by very slow oscillation, corresponds to a breakdown of communication between different brain regions, each of which experiences short bursts of activity interrupted by longer silences.
Inside the child’s brain
This 7 minute video was created for school children to show them how to maximise their brains potential. It is part of an innovative teaching program by Thinkology® aimed at increasing student academic performance and reducing aggressive behaviours such as bullying and other disruptive behaviours. This video has had a significant impact on increasing students self – esteem, controlling bullying and increasing academic performance.

Gym-style exercise may improve not only general health in middle age, but also brain function, according to new research.
Researchers at Oregon Health & Science University have discovered that blocking a certain enzyme in the brain can help repair the brain damage associated with multiple sclerosis and a range of other neurological disorders.
Researchers at the University of Minnesota’s Center for Magnetic Resonance Research (CMRR) have found a small population of neurons that is involved in measuring time.
Two proteins have a unique bond that enables brain receptors essential to learning and memory to not only get and stay where they’re needed, but to be hauled off when they aren’t, researchers say.
Scientists have discovered that the brain circuits we engage when we think about social matters, such as considering other people’s views, or moral issues, inhibit the circuits that we use when we think about inanimate, analytical
things, such as working on a physics problem or making sure the numbers add up when we balance our budget. And they say, the same happens the other way around: the analytic brain network inhibits the social network.
Lund University researchers plan to use optogenetics to stimulate neurons to release more dopamine to combat Parkinson’s disease.
A new finding could lead to strategies for treating speech loss after a stroke and helping children with dyslexia. New research links motor skills and perception, specifically as it relates to a second finding – a new understanding of what the left and right brain hemispheres “hear.”
UCLA researchers have for the first time measured the activity of a brain region known to be involved in learning, memory and Alzheimer’s disease during sleep. They discovered that this region, called the entorhinal cortex, behaves as if it’s remembering something, even during anesthesia–induced sleep — a finding that counters conventional theories about sleep-time memory consolidation.
