Higher Mental Functions of Brain: Learning and Memory01:26

Higher Mental Functions of Brain: Learning and Memory

965
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...

Direct Motor Pathways01:11

Direct Motor Pathways

2.4K
The direct motor pathways, also known as the pyramidal tracts, are a group of neural pathways that originate in the brain and descend through the spinal cord. They control the voluntary movement of the body. There are two major direct motor pathways: the corticospinal and the corticobulbar tracts.
The corticospinal tract is responsible for the voluntary movement of the limbs and trunk. It originates in the cerebral cortex of the brain and descends through the cerebrum's internal capsule and...

Role of Cerebellum and Prefrontal Cortex in Memory

571
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...

Indirect Motor Pathways01:22

Indirect Motor Pathways

1.7K
The indirect motor or extrapyramidal pathways originate in the brainstem, the lower portion of the brain that connects it to the spinal cord. They consist of several distinct tracts, each with specialized functions. The four main tracts of the indirect motor pathways are the vestibulospinal tract, the reticulospinal tract, the tectospinal tract, and the rubrospinal tract.
The vestibulospinal tract originates in the vestibular nuclei of the brainstem. The vestibular system detects changes in...

Overview of Somatic Sensory Pathways01:29

Overview of Somatic Sensory Pathways

5.3K
Somatic sensory or somatosensory pathways refer to the neural pathways that carry information related to touch, pressure, pain, temperature, and proprioception from the skin, muscles, tendons, and joints to the brain. These pathways involve several stages of processing and integration of sensory information.
The somatosensory system is divided into three main pathways: the dorsal (or posterior) column-medial lemniscus, spinothalamic (or anterolateral), and spinocerebellar pathways.
The dorsal...

Storage

131
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...

Summary

Spontaneous memories, often vivid and emotional, arise unexpectedly. A new study reveals that these involuntary memories use different brain mechanisms than those consciously recalled.

Area of Science:

  • Neuroscience
  • Cognitive Psychology

Background:

  • Memories can surface involuntarily, often with significant emotional impact.
  • Understanding the neural basis of memory recall is crucial for cognitive science.

Purpose of the Study:

  • To investigate the distinct brain mechanisms underlying involuntary and voluntary memory recall.
  • To differentiate the neural pathways involved in spontaneous versus intentional memory retrieval.

Main Methods:

  • Utilizing neuroimaging techniques to observe brain activity during memory recall tasks.
  • Comparing neural activation patterns associated with involuntary memory intrusions and voluntary retrieval.

Main Results:

  • Involuntary memory recall is associated with distinct neural activation patterns compared to voluntary recall.
  • Specific brain regions show differential engagement depending on whether memory retrieval is spontaneous or intentional.

Conclusions:

  • Involuntary and voluntary memory are supported by separate neural mechanisms.
  • This finding advances our understanding of memory processes and their underlying brain structures.
