Background:

The dorsolateral prefrontal cortex plays a crucial role in higher cognitive functions.
Understanding neuronal activity during complex tasks is key to deciphering memory and attention mechanisms.

Purpose of the Study:

To investigate the role of unit activity in the monkey's dorsolateral prefrontal cortex (s. principalis) during a delayed-response alternation task.
To elucidate the involvement of this brain region in learning, short-term memory, and attention.

Main Methods:

Multineuronal recording technique was employed to analyze unit activity.
The study focused on the sequence of events in a delayed-response alternation task, including stimuli, delay periods, and responses.
Behavioral performance and neuronal firing patterns were correlated.

Main Results:

Unit activity in the s. principalis was involved in integrating behavioral acts into a programmed sequence.
Evidence suggests short-term memory storage, indicated by successive neuronal population involvement and activity shifts during the delay period.
Neuronal activity correlated with correct response levels and was influenced by the level of attention.

Conclusions:

The dorsolateral prefrontal cortex (s. principalis) is critical for integrating complex behavioral sequences and for short-term memory storage.
Neuronal networks in this region dynamically process external signals based on attentional levels.
Findings highlight the prefrontal cortex's role in attention-modulated memory processes.
