Summary
This review covers memory research history, focusing on episodic memory. It highlights sex and age differences in healthy individuals and memory deficits in schizophrenia, particularly those with negative symptoms.
Area of Science:
- Neuroscience
- Cognitive Science
- Psychology
Background:
- Memory is crucial for survival and has been studied across species since behavioral science's inception.
- Neuroscience advances have elucidated brain systems and mechanisms underlying memory.
- Episodic memory is a key focus in cognitive neuroscience research.
Purpose of the Study:
- To review the history of memory research and its neural underpinnings.
- To describe major dimensions of memory processing evaluated by cognitive neuroscience.
- To examine sex and age effects on memory and deficits in schizophrenia.
Main Methods:
- Historical review of memory research.
- Analysis of cognitive neuroscience studies on memory processing.
- Examination of evidence for sex and age differences in healthy populations.
- Description of memory impairments in schizophrenia.
Main Results:
- Females exhibit superior verbal and face memory compared to males.
- Memory processes tend to slow down with increasing age.
- Schizophrenia patients with negative symptoms, especially flat affect, show more severe memory and social cognition deficits.
Conclusions:
- Medial temporal and frontal brain regions are implicated in schizophrenia-related memory impairments.
- Understanding memory across species and its neural basis is vital.
- Cognitive neuroscience provides critical insights into memory function and dysfunction.

01:26Higher Mental Functions of Brain: Learning and Memory
2.2K
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...

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...

01:23Role of Neurotransmitters in Memory
2.8K
Neurotransmitters are integral to the brain's communication system, enabling neurons to transmit signals across synapses. This chemical exchange underpins various cognitive functions, including memory processes. The role of neurotransmitters in memory is multifaceted, influencing the encoding, consolidation, and retrieval of memories through their action on different neural circuits.

01:19Role of Hippocampus in Memory
2.0K
The hippocampus, a critical brain structure, plays an essential role in memory processing, particularly in the formation and retrieval of memory. This small, seahorse-shaped region is located within the medial temporal lobe, with one hippocampus in each brain hemisphere. Experimental studies involving lesions in the hippocampi of rats have demonstrated significant impairments in tasks such as object recognition and maze navigation, indicating the hippocampus involvement in both recognition and...

01:03Long-term Depression
2.6K
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.
