A New Genetic Entry Point for Autism Traits

Can autism's core traits be separated from cognitive ability? Researchers have identified PTCHD1-AS, a long non-coding RNA gene that regulates social interaction and repetitive behaviors without affecting learning or memory. By tracing this gene's influence to synaptic plasticity in the striatum, the study provides a "molecular pattern" for future precision treatments aimed specifically at the hallmark features of the autism spectrum.

Brain’s “Hourglass Timer” Controls the Precise Timing of Movement

Researchers have discovered how the brain keeps time for precise movements, revealing a neural “hourglass” mechanism between the motor cortex and striatum. The motor cortex sends timing signals that accumulate in the striatum until they reach a threshold that triggers action.

Research Rewrites Striatum’s Role in Action and Movement

A new study challenges the long-held belief that the striatum is responsible for selecting actions. Researchers found that instead of making decisions, the striatum and motor cortex work together to specify movement details, such as how to reach for an object.

Study Reveals Dopamine’s Limited Role in Rapid Neural Activity

A recent study has found that dopamine signals have a minimal impact on rapid neural activity in the striatum, challenging existing theories about dopamine's role in brain signaling. Using advanced optical neural chip technology, researchers observed that dopamine signals within normal physiological ranges do not significantly affect neural processing.
