Listen to an audio version of a recent Nature feature.

A recent study demonstrated that non-invasive stimulation of the right cerebellum led to improvements in episodic memory performance in healthy elderly individuals, at the end of a 12-day neurostimulation program, and also at the point of a 4-month follow-up.

The steady increase in average life expectancy poses significant challenges to individuals, families, and societies across multiple dimensions. Estimating that by 2050 one in every six individuals will be over the age of 65, the study of aging and its association with cognitive decline, neurodegenerative diseases and overall frailty is becoming increasingly important.

Therefore, it has been an important goals of neurosciences research to understand the relationship between the aging brain and episodic memory deficits and to develop interventions to mitigate the age-related decline in our ability to remember personal past events (episodic memory).

Why do some people live lawful lives, while others gravitate toward repeated criminal behavior? Do people choose to be moral or immoral, or is morality simply a genetically inherited function of the brain? Research suggests that psychopathy as a biological condition explained by defective neural circuits that mediate empathy, but what does that mean when neuroscience is used as evidence in criminal court? How can understanding neuroscience give us an insight into the actions and behaviors of our political leaders?

Forensic psychiatrist Dr. Octavio Choi https://med.stanford.edu/profiles/ochoi will explore how emerging neuroscience challenges long-held assumptions underlying the basis—and punishment—of criminal behavior.

Lead author Jon Walbrin explains, “Most previous social neuroscience studies have focused on measuring responses to other people as individuals. But more recently there has been an increased interest in understanding brain responses to others in the context of social interactions. However, very little is currently known about how such responses develop during childhood.”

“These results suggest that children and adults might employ different strategies for interaction understanding: Adults rely more on observable, body-based information, while children—with less social experience—engage more in effortful reasoning about what others are thinking and feeling during an interaction. This likely reflects the process of learning to understand interactive behavior.”

Neuroscientists have uncovered how exploratory actions enable animals to learn their spatial environment more efficiently. Their findings could help build better AI agents that can learn faster and require less experience.

Researchers at the Sainsbury Wellcome Center and Gatsby Computational Neuroscience Unit at UCL found the instinctual exploratory runs that animals carry out are not random. These purposeful actions allow mice to learn a map of the world efficiently. The study, published today, April 28, in Neuron, describes how neuroscientists tested their hypothesis that the specific exploratory actions that animals undertake, such as darting quickly towards objects, are important in helping them learn how to navigate their environment.

“There are a lot of theories in psychology about how performing certain actions facilitates learning. In this study, we tested whether simply observing obstacles in an environment was enough to learn about them, or if purposeful, sensory-guided actions help animals build a cognitive map of the world,” said Professor Tiago Branco, Group Leader at the Sainsbury Wellcome Center and corresponding author on the paper.

In this episode, I discuss how our brain and body track time and the role that neurochemicals, in particular dopamine and serotonin, but also hormones such as melatonin, allow us to orient ourselves in time. I review the three types of time perception: of the past, of the present, and the future, and how dopamine and serotonin adjust both our perception of the speed of the passage of time and our memory of how long previous experiences lasted. I also discuss circannual entrainment, which is the process by which our brain and body are matched to the seasons, and circadian (24 hours) entrainment, both of which subconsciously adjust our perceived measurement of time. I explain the mechanisms of that subconscious control. And I cover the ultradian (90 minutes) rhythms that govern our ability to focus, including how to track when these 90-minute rhythms begin and end for the sake of work and productivity. I include ten tools based on the science of time perception that you can apply to enhance productivity, creativity, and relationships in various contexts.

The human body relies heavily on electrical charges. Lightning-like pulses of energy fly through the brain and nerves and most biological processes depend on electrical ions traveling across the membranes of each cell in our body.

These electrical signals are possible, in part, because of an imbalance in electrical charges that exists on either side of a cellular membrane. Until recently, researchers believed the membrane was an essential component to creating this imbalance. But that thought was turned on its head when researchers at Stanford University discovered that similar imbalanced electrical charges can exist between microdroplets of water and air.

Now, researchers at Duke University have discovered that these types of electric fields also exist within and around another type of cellular structure called biological condensates. Like oil droplets floating in water, these structures exist because of differences in density. They form compartments inside the cell without needing the physical boundary of a membrane.

Neuroscientists and archeologists have wrestled with the Sapient Paradox for decades. Can collective learning be the solution?
