The timing of the cognitive cycle.

Area of Science:

• Cognitive Neuroscience
• Computational Neuroscience
• Artificial Intelligence

Background:

• Human cognition is theorized to involve recurring cycles of brain events.
• The LIDA (Learning Intelligent Distribution Agent) model proposes a fundamental cognitive cycle.
• Previous models lack detailed timing and neurobiological integration.

Purpose of the Study:

• To describe a timing model for the LIDA cognitive cycle.
• To align the cognitive cycle with empirical neuroscientific evidence.
• To demonstrate the model's application in simulating cognitive tasks.

Main Methods:

• Development of a timing model for the LIDA cognitive cycle based on empirical and simulation data.
• Analysis of neurophysiological evidence, including theta-gamma waves and brain region involvement.
• Implementation of LIDA-based software agents for reaction time and simultaneity tasks.

Main Results:

• A cognitive cycle duration of 260-390 ms is proposed, with perception (80-100 ms), conscious broadcast (200-280 ms), and action selection (60-110 ms post-broadcast).
• The model aligns with theta-gamma wave propagation in corticothalamic systems and involvement of frontal, striatal, and cerebellar regions.
• LIDA agents accurately simulated human performance in reaction time and simultaneity tasks.

Conclusions:

• The LIDA cognitive cycle provides a biologically and computationally plausible framework for understanding human cognition.
• The proposed timing model is consistent with key neuroscientific findings.
• The model's success in simulations highlights its potential for further research in cognitive architectures.
