Article Synopsis
  • The study explores how different types of feedback (reinforcement and error) influence movement exploration, revealing distinct roles for the basal ganglia (linked to reinforcement) and the cerebellum (linked to error correction).
  • Experiments conducted with both neurotypical individuals and those with Parkinson's disease show that reinforcement feedback encourages exploration, while error feedback suppresses it; together they can counteract each other.
  • Findings indicate that individuals with Parkinson's have reduced exploration abilities when receiving reinforcement feedback, which could inform strategies for neurorehabilitation.

Physical therapy is often essential for complete recovery after injury. However, a significant population of patients fail to adhere to prescribed exercise regimens. Lack of motivation and inconsistent in-person visits to physical therapy are major contributing factors to suboptimal exercise adherence, slowing the recovery process.

Aims And Background: Acute poisoning is one of the most common emergencies in India and around the world. Understanding the factors associated with mortality can aid us in devising appropriate preventive strategies to curtail deaths due to poisoning. Purpose of this study is to find various factors that determine the mortality among acute poisoning cases admitted in a tertiary care center.

When a musician practices a new song, hitting a correct note sounds pleasant while striking an incorrect note sounds unpleasant. Such reward and punishment feedback has been shown to differentially influence the ability to learn a new motor skill. Recent work has suggested that punishment leads to greater movement variability, which causes greater exploration and faster learning.

From a baby's babbling to a songbird practising a new tune, exploration is critical to motor learning. A hallmark of exploration is the emergence of random walk behaviour along solution manifolds, where successive motor actions are not independent but rather become serially dependent. Such exploratory random walk behaviour is ubiquitous across species' neural firing, gait patterns and reaching behaviour.
