Interdependence of "What" and "When" in the Brain

Area of Science:

• Neuroscience
• Computational Neuroscience
• Cognitive Science

Background:

• The perception of sensory information is often studied by dichotomizing 'what' (content) and 'when' (timing).
• This separation overlooks the interdependent relationship between stimulus content and temporal processing in the brain.
• Neural temporal dynamics and perceptual events exhibit significant variability, which is frequently not modeled.

Approach:

• This work reviews the interplay between 'what' and 'when' in neural processing.
• Simulations demonstrate how ignoring temporal variability can lead to flawed interpretations.
• The study advocates for integrating 'what' and 'when' into computational models of the brain.

Key Points:

• Neural temporal dynamics influence perceived stimulus content.
• Stimulus content affects the timing of perceptual achievement.
• Temporal variability in neural and perceptual processes is critical for understanding brain function.

Conclusions:

• A unified approach to 'what' and 'when' is essential for accurate brain modeling.
• Ignoring temporal variability risks misinterpreting data and hindering theoretical advancements.
• Integrating temporal dynamics is key to building robust theories of neural computation.
