Memory in neuroscience: rhetoric versus reality.

Area of Science:

• Neuroscience
• Cognitive Science
• Neurobiology

Background:

• The prevailing view of memory in neuroscience treats the brain as an information storage system.
• This perspective is rooted in the sensorimotor hypothesis, which posits the nervous system's primary role is to link sensory input to behavioral output.

Observation:

• Memories are redefined as complex sequences of events, not static data points.
• These sequences bridge remote experiences with current behaviors, involving persistent and junctional events.
• Even simple memories exhibit complexity due to the need to preserve learned behaviors and inherent neural plasticity.

Findings:

• The concept of memory as mere information storage is inadequate for understanding the nervous system.
• A new model defines memory as dynamic event sequences connecting past and present behavior.
• This sequence-based understanding is crucial for accurate neurobiological models.

Implications:

• This reframing challenges traditional neuroscience models of memory.
• It emphasizes the dynamic and sequential nature of neural processing.
• Future research should focus on the complex event sequences underlying memory and behavior.
