Background:

The neostriatum, a major basal ganglia component, receives cortical and thalamic inputs.
Interneurones in the neostriatum have remained poorly understood despite extensive research.

Purpose of the Study:

To identify the specific types and functions of neostriatal interneurones.
To elucidate the roles of these interneurones within the neostriatal circuitry.

Main Methods:

Utilized cytochemical markers specific to striatal interneurone classes.
Employed intracellular recording and staining techniques.
Combined molecular and electrophysiological approaches.

Main Results:

Successfully identified major classes of striatal interneurones.

Characterized functional properties of these interneurones.

Provided insights into their integration within neostriatal circuits.

Conclusions:

Recent advancements have resolved the long-standing enigma of striatal interneurone identity.
These findings offer a new understanding of neostriatal circuitry and function.
