Treating Depression: Deep Brain Stimulation (UCSF)

UCSF Health physicians have successfully treated a patient with severe depression by tapping into the specific brain circuit involved in depressive brain patterns and resetting them using the equivalent of a pacemaker for the brain.

Science Of The Brain: What Is Interoception? (Scripps)

Your brain is keenly aware of what’s going on inside your body at all times. Some things are obvious – like when you feel hungry or thirsty. But some things you never notice – like how blood vessels all over your body simultaneously contract as you stand up, so you don’t lose blood flow to your brain. But how does your brain know when to send the signal to squeeze? It’s all part of concept scientists call interoception – the dialogue between your brain and the rest of your body.

Interoception is involved in everything from keeping us balanced while we walk, to keeping our blood pressure and heart rate steady. It even appears to influence our moods and emotions. And thanks to recent discoveries, we’re learning more about how interoception works. Researchers identified two special channels in neurons that react to touch and named them PIEZO1 and PIEZO2. Since first identifying these pressure sensors, researchers have found PIEZOs in internal organs like the heart, lungs, and blood vessels lining the stomach… suggesting many physiological functions involve mechanical forces that our brain and other parts of our nervous system must monitor and influence. As the study of interoception grows, scientists are hopeful the field could lead to breakthroughs in treating heart disease, controlling blood pressure, relieving anxiety and depression, and treating a number of other disorders.

Health: Recognizing A Stroke (Cleveland Clinic)

If you don’t know the signs of a stroke, you’re not alone. Thirty percent of people under the age of 45 don’t either. The key is to B.E. F.A.S.T. Learn how this acronym can help you save a life. The information in this video is accurate as of 9.17.21 and is for information purposes only. Consult your local medical authority or your healthcare practitioner for advice.

Analysis: The Cognitive Effects Of Covid-19

Covid-19 is complex. It can affect the nervous system, leading to language disorders, strokes and seizures. Scientists are still trying to understand why. 75% of people hospitalised with the virus continue to suffer from secondary symptoms at least six months after they recover. Many find it hard to function in their daily lives. Researchers hope understanding Covid’s impact on the brain could pave a way for treatment.

Exercise: The Evolution Of Human Physical Activity

Human physical activities differ significantly from other species. How, when and why did these capabilities evolve? What adaptations underlie them? And how did the evolution of human physical activity affect other key human characteristics that have advanced our species?

Herman Pontzer explores the evolution of human metabolism and its role in our evolution and health. From an evolutionary perspective, life is a game of turning energy into offspring. The strategies that species use to acquire energy, in the form of food, and allocate energy to the essential tasks of growth, maintenance, movement, and reproduction, are incredibly diverse and reflect the ecological pressures and opportunities encountered. There is a deep evolutionary history of the human metabolic strategy and our divergence from other apes.
