Role of Cerebellum and Prefrontal Cortex in Memory01:14

Role of Cerebellum and Prefrontal Cortex in Memory

The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the cerebellum's...
Neuroplasticity01:01

Neuroplasticity

Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.
Plasticity00:58

Plasticity

Plasticity is the property where an object loses its elasticity and undergoes irreversible deformation, even after the deformation forces are eliminated. If a material deforms irreversibly without increasing stress or load, then this is called ideal plasticity. For example, when a force is applied to an aluminum rod, it changes its shape, but it does not return to its original shape once the force is removed. Plastic deformation or ductility is thus a permanent deformation or change in the...
Higher Mental Functions of Brain: Learning and Memory01:26

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 playing an...
Long-term Potentiation01:25

Long-term Potentiation

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

Area of Science:

  • Neuroscience
  • Cognitive Psychology

Background:

  • Human studies link the prefrontal cortex (PFC) to long-term memory, typically viewing it as crucial for executive control, not storage.
  • Existing research often overlooks the PFC's potential role in the physical storage of long-term memories.

Purpose of the Study:

  • To explore the accumulating evidence suggesting the PFC's involvement in long-term memory storage.
  • To propose a new framework, 'control memory,' to define the PFC's unique contribution to memory.

Main Methods:

  • Review of existing neuropsychological and neuroimaging studies in humans.
  • Analysis of recent animal studies, including projection system analysis, recording studies, and behavioral/physiological research.

Main Results:

  • Evidence indicates PFC projection systems support long-term synaptic plasticity.
  • Neural correlates of learning have been observed in the PFC across species.
  • PFC is critically involved in memory consolidation, retrieval, and extinction.

Conclusions:

  • The PFC appears to be an integral component of the neural network for long-term memory storage and retrieval.
  • The concept of 'control memory' is proposed to encapsulate the PFC's role in memory for top-down control processes.
  • This new perspective may help organize current data and guide future research on PFC and memory.
