Topic: biological mechanisms

Jaan Aru examines biological mechanisms that may matter for consciousness, including dendritic integration and interactions between cortex and thalamus. The discussion connects these mechanisms to cognition and prospects for artificial consciousness, then explores insight and creativity across ordinary problem-solving and altered experiences.

Over the past thirty years or so, cognitive neuroscience has made spectacular progress understanding the biological mechanisms of consciousness. Consciousness science, as this field is now sometimes called, was not only inexistent thirty years ago, but its very name seemed like an oxymoron: how can there be a science of consciousness? And yet, despite this scepticism, we are now equipped with a rich set of sophisticated behavioural paradigms, with an impressive array of techniques making it possible to see the brain in action, and with an ever-growing collection of theories and speculations ab

Nearly every aspect of life involves decisions between options that differ in both their expected rewards and the potential costs (such as delay to reward delivery or risk of harm) that accompany those rewards. The ability to choose adaptively when faced with such decisions is critical for well-being and overall quality of life. In neuropsychiatric conditions such as substance use disorders, however, decision making is often compromised, which can prolong and exacerbate their severity and co-morbidities. In this seminar, Dr. Setlow will discuss research in rodent models investigating behaviora
