Growing evidence from clinical trials, epidemiological and neuroscience research suggests that physical exercise is a promising intervention for delaying the onset of dementia and Alzheimer’s disease. Further, physical activity has been shown to have notable beneficial effects on brain structure, both microstructure and macrostructure. In contrast to the large literature on physical activity, there is a paucity of research on the relationship between sedentary

behavior and dementia risk. This is concerning given that sedentary behaviors may be independent from exercise and other physical activities, and therefore warrant independent
inquiry. Indeed, one can be highly active yet still be sedentary for most of the day.

Several lines of evidence suggest that sedentary behavior may be a risk factor for the development of age-related cognitive impairment. A detailed projection of the effect of risk
factors on Alzheimer’s disease (AD) prevalence suggests that approximately 13% of AD cases worldwide may be attributable to sedentary behavior. A 25% reduction in sedentary behavior could potentially prevent more than 1 million AD cases globally

A lacrosse player takes a blow to the head from an opponent’s stick but remains conscious and keeps playing. A parent hits their head on a cabinet door while making school lunches but has no time to slow down. An elderly person becomes dizzy and falls, landing on their knees, but the force involved jostles their brain.

They may seem minor, but each of these injuries could lead to a concussion. Without treatment, a concussion can have lasting effects on a person’s mental, physical, and emotional health.

A mental health counselor can support someone in the aftermath of a concussion and guide people in their support networks—family, friends, coaches, teachers, and employers—helping them better understand what a concussion is and how they can be of assistance.

Because a concussion affects the way an individual interacts with the world, recovery takes time and can involve making changes in daily routine and asking for support from one’s community.

A mental health counselor can be an important resource during concussion recovery. An expert in sport and exercise psychology, Dr. Kerulis shared a number of ways in which counselors can offer support.

A new study promises new paths to research mental illness, but raises questions about whether so-called organoids
could develop consciousness
Alysson Muotri was dumbfounded when the pea-sized blobs of human brain cells that he was growing in the lab started emitting electrical pulses. He initially thought the electrodes he was using were malfunctioning.

Muotri was wrong. What the cells were emitting were brain waves — rhythmic patterns of neural activity. “That was a big surprise,” he says.

The 3D blobs of brain cells, known as organoids, are commonly used in disease and drug research to replicate organs. But no “mini-brain” had ever shown signs of brain waves before.
That was in 2016. Now, Muotri and his colleagues at the University of California, San Diego, have detailed their findings on the organoids in a new study in the journal Cell Stem Cell.
Scientists are a long way from understanding the human brain. Organoids that emit brain waves could open up new opportunities for research.

But as mini-brains become better replicas for real brains, they raise ethical questions about where sentience begins, and whether these blobs of tissue need protections of the sort offered to animals and humans in research.

A Nobel Prize–winning neuroscientist’s probing investigation of what brain disorders can tell us about human nature

Eric R. Kandel, the winner of the Nobel Prize in Physiology or Medicine for his foundational research into memory storage in the brain, is one of the pioneers of modern brain science. His work continues to shape our understanding of how learning and memory work and to break down age-old barriers between the sciences and the arts.

In his seminal new book, The Disordered Mind, Kandel draws on a lifetime of pathbreaking research and the work of many other leading neuroscientists to take us on an unusual tour of the brain. He confronts one of the most difficult questions we face: How does our mind, our individual sense of self, emerge from the physical matter of the brain? The brain’s 86 billion neurons communicate with one another through very precise connections. But sometimes those connections are disrupted.

The brain processes that give rise to our mind can become disordered, resulting in diseases such as autism, depression, schizophrenia, Parkinson’s, addiction, and post-traumatic stress disorder. While these disruptions bring great suffering, they can also reveal the mysteries of how the brain produces our most fundamental experiences and capabilities―the very nature of what it means to be human. Studies of autism illuminate the neurological foundations of our social instincts; research into depression offers important insights on emotions and the integrity of the self; and paradigm-shifting work on addiction has led to a new understanding of the relationship between pleasure and willpower.

5) Quote We Are Contemplating...

"When the green woods laugh with the voice of joy, And the dimpling stream runs laughing by; When the air does laugh with our merry wit, And the green hill laughs with the noise of it. "
