Storage

Storage

A schema is a mental framework that helps individuals organize and interpret information. Schemata, formed from previous experiences, influence how we process new information: how we encode it, the inferences we make, and how we retrieve it. For instance, a schema for what a typical classroom looks like might include desks, a teacher's desk, a whiteboard, and students in such an environment. This expectation helps us quickly understand and navigate new classrooms without needing to analyze each...

Understanding Memory

Understanding Memory

Memory is the retention of information or experiences over time, facilitated through three main processes: encoding, storage, and retrieval. Encoding is the process of inputting information into the memory system. For instance, when listening to a lecture, watching a play, reading a book, or having a conversation, the brain is actively encoding information. This initial stage involves transforming sensory input into a form that can be processed and stored by the brain. Various factors, such as...

Calmodulin-dependent Signaling

Calmodulin-dependent Signaling

Calmodulin (CaM) is a calcium-binding protein in eukaryotes that controls various calcium-regulated cellular processes. It has four calcium-binding sites that bind calcium to form the calcium-calmodulin ( Ca2+-CaM) complex. GPCR stimulation increases the calcium levels in the cells that bind to CaM and induces a conformational change.
The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...

Long-term Depression

Long-term Depression

Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Interference and Decay

Interference and Decay

Forgetting is a complex cognitive phenomenon influenced by several factors, among which interference and decay are particularly prominent. These processes explain why individuals often struggle to retrieve specific information from memory, leading to lapses in recall that can be observed in everyday situations.
Interference occurs when competing memories hinder the retrieval of particular information. It can be classified into two types: proactive and retroactive interference. Proactive...

Summary

Neural communication in memory relies on brain wave synchronization. Theta and alpha brain waves coordinate working memory, semantic, and episodic memory access and control processes.

Background:

Large-scale neural communication is crucial for cognitive functions.
Oscillatory phase synchronization is hypothesized to bind cognitive processes.
Understanding synchronization mechanisms in memory is key.

Purpose of the Study:

To investigate the role of oscillatory synchronization in memory processes.
To explore how different synchronization mechanisms support large-scale neural communication in memory.

Main Methods:

Review of existing findings on oscillatory synchronization and memory.
Analysis of theta and alpha phase coupling and reorganization in memory systems.

Main Results:

Theta and alpha phase coupling reflect control processes in working memory and semantic long-term memory.
Alpha phase synchronization coordinates top-down control and memory trace access.
Theta oscillations are linked to controlled access of episodic memories.

Conclusions:

Oscillatory phase synchronization, specifically theta and alpha coupling, is fundamental for large-scale neural communication in memory.
These synchronization mechanisms facilitate control processes and memory access within distinct memory systems.
