Concept
The beta-sheet structure is a fundamental element of protein secondary structure characterized by beta strands linked laterally by at least two or three backbone hydrogen bonds, forming a sheet-like arrangement. This structure contributes to the stability and functionality of proteins and is crucial in the formation of protein complexes and aggregation-related diseases like Alzheimer's.

Concept
Sensory memory is the shortest-term element of memory, acting as a buffer for stimuli received through the senses before they are processed into short-term memory. It allows individuals to retain impressions of sensory information after the original stimulus has ceased, facilitating the initial stage of perception and attention.
Concept
Short-term memory is a cognitive system that temporarily holds a limited amount of information, typically for about 15 to 30 seconds, before it is either forgotten or transferred to long-term memory. It plays a crucial role in everyday tasks, such as language comprehension and problem-solving, by allowing individuals to retain and manipulate information in the moment.
Concept
Long-term memory is a cognitive system that stores information indefinitely, allowing for the retrieval of knowledge and experiences over extended periods. It is crucial for learning, personal identity, and the ability to perform complex tasks by retaining and integrating information from past experiences.
Concept
Working memory is a cognitive system with a limited capacity that is responsible for temporarily holding information available for processing. It plays a crucial role in reasoning, decision-making, and behavior by allowing individuals to manipulate and utilize information in real-time.
Concept
Encoding is the process of converting information from one format or system into another, enabling efficient storage, transmission, and interpretation by machines or humans. It is fundamental in fields such as data communication, computer science, and cognitive psychology, where it facilitates the transformation of data into a form that can be easily processed and understood.
Concept
Storage refers to the process of retaining digital or physical data in a secure and organized manner for future access and use. It encompasses various technologies and methodologies to ensure data integrity, availability, and efficient retrieval.
Concept
Retrieval refers to the process of accessing and bringing information from memory into conscious awareness, which is crucial for learning and decision-making. Effective retrieval relies on cues and context, and is enhanced by practices like spaced repetition and retrieval practice, which strengthen memory pathways.
Concept
Explicit memory, also known as declarative memory, involves the conscious recall of information such as facts and events. It is subdivided into episodic memory, which pertains to personal experiences, and semantic memory, which involves general world knowledge.
Concept
Implicit memory is a type of long-term memory that does not require conscious thought and is often demonstrated through performance rather than recollection. It encompasses skills and conditioned responses that have been acquired through repetition and practice, allowing individuals to perform tasks without conscious awareness of the learned experience.
Concept
Declarative memory is a type of long-term memory responsible for storing facts and events that can be consciously recalled and articulated. It is divided into two main categories: episodic memory, which pertains to personal experiences, and semantic memory, which involves general knowledge and facts about the world.
Concept
Procedural memory is a type of long-term memory responsible for knowing how to perform tasks and actions, such as riding a bike or typing on a keyboard, without conscious awareness. It is deeply rooted in motor skills and habits, and relies on the basal ganglia and cerebellum for execution and learning of these routines.
Concept
Episodic memory is a type of long-term memory that involves the recollection of specific events, situations, and experiences, allowing individuals to travel back in time to relive past experiences. It is crucial for personal identity and understanding the continuity of one's life, as it enables the conscious recall of personal events with contextual details such as time and place.
Concept
Semantic memory is a type of long-term memory that involves the storage and recall of general world knowledge, facts, and concepts, which are not tied to personal experiences. It enables individuals to understand language, recognize objects, and utilize learned information in everyday situations without needing to remember the context in which the knowledge was acquired.
Concept
Memory consolidation is the process by which short-term memories are transformed into stable, long-term memories, primarily occurring during sleep. This process involves the strengthening of neural connections and is crucial for learning and memory retention.
Concept
Neural plasticity, also known as brain plasticity, is the ability of the brain to change and adapt in response to experience, learning, or injury by reorganizing its structure, function, or connections. This adaptability is crucial for development, learning new skills, memory formation, and recovery from brain injuries.
Concept
Cognitive Neuroscience is an interdisciplinary field that explores the neural mechanisms underlying cognitive processes, integrating insights from psychology, neuroscience, and computational modeling. It aims to understand how brain function gives rise to mental activities such as perception, memory, language, and decision-making.
Concept
Information processing is the transformation, storage, and retrieval of information within a system, often modeled after human cognition. It is fundamental to understanding how both biological and artificial systems handle data and make decisions.
Concept
A knowledge structure is an organized body of information stored in memory, facilitating the understanding, retrieval, and application of the information. These structures help in recognizing patterns and relationships within data, leading to more efficient problem-solving and decision-making.
