Researchers have discovered two new brain pathways that modify movement and emotional decisions by controlling dopamine release. These pathways, found in the striatum, either stimulate or inhibit dopamine-producing neurons, influencing the go and no-go pathways that control movement.

Researchers have developed an AI system that predicts chemical compounds capable of targeting two proteins simultaneously, potentially creating more effective medications. By training the AI with a chemical language model, it was able to generate novel molecular structures with dual-target activity, an essential feature for treating complex diseases like cancer.

New research shows that sleep deprivation during early development disrupts brain function, impacting neuron growth and synapse formation. The study found that young mice lacking sleep did not experience the “sleep rebound” seen in adults, leading to lasting deficits in social behavior and memory.

Researchers have created "mini-brains" using stem cells from patients with a rare form of autism, allowing them to study brain development in detail. These organoids revealed how a genetic mutation in MEF2C disrupts the balance between excitatory and inhibitory neurons, leading to autism.
