Amygdala Shifts Between Learning Strategies to Enable Flexible Choices

New Dartmouth-led research reframes the amygdala as a dynamic arbiter that toggles between action-based and stimulus-based learning under uncertainty, promoting flexible decision-making. When the amygdala is damaged, arbitration becomes random and behavior locks into rigid action-based patterns. The findings offer a potential path for treating phobias and anxiety by encouraging action-based exploration over stimulus-driven fear, and pave the way for further studies on how the amygdala coordinates with prefrontal circuits to guide learning.

AI Users Split: Learners Fuel Knowledge, Others Skip Learning, Cuban Says

Mark Cuban says there are two types of AI users—those who use AI to learn everything and those who use it to avoid learning—urging companies to embrace AI while acknowledging its flaws; other tech leaders warn that overreliance on AI can deskill workers, though AI can act as a potent accelerant for career differentiation.

Timing Trumps Repetition: The Brain Learns Faster with Sparse Rewards

A UCSF study shows the brain learns more efficiently when rewards are rare and spaced apart, with dopamine responses driven by the time between cue and reward rather than the number of repetitions. This challenges Pavlovian practice-as-learning and explains why cramming is less effective, while suggesting educational strategies and potential faster, sparse-learning approaches for AI.

Brain sculpting isn’t fantasy: adulthood can change its structure and function

For much of the 20th century, scientists believed the adult brain was fixed, but neuroplasticity now shows the brain can change throughout life in response to experience—though changes are gradual and bounded. The article traces this shift from Hebb’s 1949 idea to modern imaging that reveals learning reshapes brain activity and connectivity, with the hippocampus showing limited adult neurogenesis. Change is strongest with effortful, meaningful engagement and is enhanced by practice, regular exercise (which raises BDNF) and sleep, while chronic stress can impair plasticity. Plasticity can be maladaptive, reinforcing harmful patterns like chronic pain or addiction, but therapies such as cognitive behavioral therapy and rehab can steer it toward recovery. The piece also debunks myths of rapid, limitless change, emphasizing that real brain remodeling comes from challenging, real-life activities like language learning, playing music, and complex social interaction.
