Researchers found a link between mild Covid infections impaired hippocampal neurogenesis, decreased oligodendrocytes and myelin loss in mice one week after infections persisting until at least seven weeks leading them to conclude that even those with mild symptoms in the acute phase may experience lasting cognitive dysfunction.

In this paper, we integrate recent theoretical and empirical developments in predictive coding and active inference accounts of interoception (including the Embodied Predictive Interoception Coding model) with working hypotheses from the theory of ...

This episode I interview Dr. Anna Lembke, MD, Chief of the Stanford Addiction Medicine Dual Diagnosis Clinic at Stanford University School of Medicine. Dr. Lembke is a psychiatrist expert in treating addictions of all kinds: drugs, alcohol, food, sex, video games, gambling, food, medication, etc. Dr. Lembke is also an expert in the opioid crisis, and the author of Dopamine Nation: Finding Balance in the Age of Indulgence. We discuss the biology and psychology of why people become addicted to certain substances and behaviors and the key role that our "dopamine balance" plays in creating addiction. We also discuss the science and practice of how to conquer addictions, why people relapse and how to avoid relapsing. Dr. Lembke also shares her expertise on topics closely related to addiction such as community, shame and lying and she explains why telling the truth—even about the most basic things in daily life, adjusts dopamine levels in our brain. This episode is an important one for anyone struggling with addictions of any kind, for their friends and families and for health care professionals. It is also for anyone who has defeated addiction and is determined to stay clean. Last but not least, it helps explain why all humans do what we do, and how we can all maintain a healthy sense of pleasure seeking in life.

But it’s never too late (nor too soon) to take these preventive steps

We seek novelty, but not too much.

The research, tracking thousands of people from age 50 on, suggests those who sleep six hours or less a night are more likely to develop dementia in their late 70s.

What and how much we eat isn’t the only important thing when it comes to healthy nutrition. Timing seems to matter, too.

An emerging branch of neuroscience asks a question long on the minds of researchers. Recent stimulus payments make the study more relevant.
