Encoding

Encoding

Information enters the brain through encoding, which is the input of information into the memory system. Once sensory information is received from the environment, the brain labels or codes it. The information is then organized with similar information and connected to existing concepts. Encoding occurs through automatic processing and effortful processing.
Automatic processing involves the encoding of details like time, space, frequency, and the meaning of words, usually done without conscious...

Long-Term Memory

Long-Term Memory

Long-term memory is a relatively permanent type of memory, capable of storing vast amounts of information over extended periods. Its storage capacity is generally considered unlimited.
Long-term memory can be categorized into two primary types: explicit and implicit memory. Explicit memory, also known as declarative memory, involves the conscious recollection of information that we deliberately try to remember, recall, and articulate. This type of memory encompasses specific facts, events, and...

Mnemonic Devices

Mnemonic Devices

Mnemonic devices are cognitive tools that facilitate memory retention by linking new information to familiar patterns or organizational strategies. These techniques are beneficial for remembering complex or lengthy sets of information by simplifying and structuring them in easily retrievable ways.
Acronyms
Acronyms are created by using the initial letters of a series of words to form a new word or phrase. This approach condenses complex information into a single, memorable entity. For example,...

System of Memory

System of Memory

Memory is categorized into three major systems: sensory memory, short-term memory (STM), and long-term memory (LTM). These systems differ in their capacity and the duration for which they can hold information. Sensory memory captures raw sensory input from the environment, holding it for just a few seconds or less. For example, on hearing a brief, loud sound, like a car horn honking, the sound seems to linger in the mind for a moment even after it stops. This is an instance of sensory memory...

Higher Mental Functions of Brain: Learning and Memory

Higher Mental Functions of Brain: Learning and Memory

Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or...

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...

Area of Science:

Neuroscience
Cognitive Science
Philosophy of Mind

Background:

The engram, the neural substrate of memory, has been a central pursuit in neuroscience.
Recent technological advancements have led some to claim the search for the engram is complete.
This renewed focus highlights the need for a more nuanced understanding of the engram concept.

Purpose of the Study:

To provide a historical perspective on the search for the engram.
To propose a path forward for a more precise and comprehensive understanding of the engram.
To address the limitations of characterizing the engram solely as an enduring physical change.

Main Methods:

Historical analysis of engram research.
Conceptual review of memory mechanisms.
Philosophical inquiry into the foundations of cognitive science.

Main Results:

The concept of the engram is currently oversimplified.
Existing research on the engram is insufficient to fully explain memory.
A more detailed and precise characterization of the engram is necessary.

Conclusions:

The 21st-century project in neurobiology should focus on enriching our understanding of the engram.
Moving beyond the mere identification of the engram requires a deeper exploration of its properties and functions.
A more sophisticated framework is needed to interpret the findings related to the neural mechanisms of memory.
