Background Transcranial direct current stimulation (tDCS) is one of the most widely used noninvasive neuromodulation methods. Despite its popularity, some recent studies highlighted issues about the r...

Injectable fluorescent nanoparticles were used to track positions on and inside of freely moving animals at high resolution.

Puthussery’s discoveries about the retina are paving the way for new treatments for eye disease and vision loss

Neural mechanisms underlying flexible learning and decision-making are not fully understood. Using single-cell calcium imaging, authors here found that neurons in orbitofrontal and secondary motor cortex exhibit complementary roles in reward learning, with neurons in the former exerting a sustained role in conditions of uncertainty.

Does RL teach LLMs genuinely new skills, or does it merely activate existing ones? This question lies at the core of ongoing debates about the role of RL in LLM post-training. On one side, strong empi...

Children successfully solved a challenging sorting task by spontaneously discovering efficient sorting strategies, such as selection sort and shaker sort. Older children outperformed younger ones, demonstrating developmental progress in strategic thinking and problem-solving abilities.

This study offers a novel approach for benchmarking complex cognitive behavior in artificial systems. Almost universally, Large Language Models (LLMs) perform best on tasks which may be included in th...

Understanding behavior requires datasets that capture humans while carrying out complex tasks. The kitchen is an excellent environment for assessing human motor and cognitive function, as many complex...

An academic website serves as both a public-facing window on the world wide web and an important internal laboratory resource. In this ‘How to’ piece, I outline how to build your academic website, including what content to include, and ways to build and launch your site.

The brain has somewhat separate cognitive resources for the left and right sides of our visual field. Despite this lateralization, we have a smooth and unified perception of our environment. This rais...
