memory trace
Noun: A hypothesized physical alteration in the brain, specifically in neural tissue, thought to be the biological basis for storing a memory. It is a theoretical construct representing how information is encoded and retained in the nervous system.
The term is used primarily in neuroscience and cognitive psychology to discuss the physical substrate of memory. - It is often discussed in the context of memory formation, consolidation, and retrieval. - It is a theoretical concept; the exact nature of the "trace" is a subject of ongoing research.
- Scientists are searching for the specific memory trace for that learned fear response.
- The theory suggests that each new memory creates a unique memory trace in the brain.
- Damage to the hippocampus can disrupt the formation of new memory traces.
- Engram: This is a synonym often used interchangeably with "memory trace" to describe the physical representation of memory.
- Synaptic plasticity: This is a key mechanism believed to underlie the creation of memory traces, referring to the strengthening or weakening of synapses between neurons.
- Engram (n): Another term for a memory trace; the physical embodiment of memory.
- Memory consolidation (n): The process by which a temporary, fragile memory trace becomes stable and long-lasting.
- Engram
- Neural representation of memory
"Memory trace" is a compound noun. The core word "trace" here means a vestige or indication of something that exists or has occurred. In this specialized context, it refers to the hypothesized physical remnant of an experience within the brain's neural architecture.
- a postulated biochemical change (presumably in neural tissue) that represents a memory
