Summary
The cerebellum, long overlooked in neuroimaging, is crucial for cognitive functions. Its exclusion limits our understanding of whole-brain activity and neurological disorders.
Area of Science:
- Neuroscience
- Cognitive Science
- Neuroimaging
Background:
- The cerebellum, traditionally viewed as a motor control center, is increasingly recognized for its significant role in diverse cognitive functions.
- Historically, the cerebellum has been underrepresented or excluded from comprehensive 'whole-brain' neuroimaging research.
- This exclusion has potentially hindered a complete understanding of brain function and its complex networks.
Purpose of the Study:
- To investigate the reasons behind the historical exclusion of the cerebellum from neuroimaging studies.
- To review existing literature highlighting the cerebellum's critical role in cognitive processes.
- To discuss the implications of this exclusion for understanding brain function and clinical conditions.
Main Methods:
- Literature review of historical and current neuroimaging studies.
- Analysis of reasons for cerebellum exclusion (warranted and unwarranted).
- Synthesis of evidence on cerebellar contributions to cognition.
Main Results:
- Identified historical biases and methodological challenges contributing to cerebellum exclusion.
- Compiled evidence demonstrating the cerebellum's integral role in cognitive functions beyond motor control.
- Highlighted the negative impact of cerebellum exclusion on understanding brain disorders.
Conclusions:
- The continued exclusion of the cerebellum from neuroimaging research limits a holistic understanding of brain function.
- Re-integrating the cerebellum into 'whole-brain' studies is essential for advancing neuroscience and clinical neurology.
- Future research should prioritize comprehensive brain imaging that includes the cerebellum to fully elucidate its cognitive and clinical significance.

01:14Role of Cerebellum and Prefrontal Cortex in Memory
342
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...

01:28Major Somatic Sensory Pathways
867
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...

The cerebellum, also known as the "little brain," is located in the posterior cranial fossa, inferior to the tentorium cerebelli and dorsal to the brainstem. It plays a significant role in motor control, coordination, and proprioception.
Cerebellar Structure
Externally, the cerebellum features a highly convoluted surface with numerous folia (narrow ridges) separated by shallow sulci (grooves). The cerebellum is divided into two hemispheres by a thin median structure known as the vermis....

01:01Neuroplasticity
269
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.

01:05Cerebral Hemispheres
287
The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...

01:27Diencephalon: Thalamus and Information Relay
1.4K
The thalamus, often called “the gateway to the cerebral cortex,” is vital in processing and directing sensory and motor signals throughout the brain. Almost all inputs destined for the cerebral cortex, except for olfactory signals, are relayed through the thalamus. The thalamus is a sophisticated relay station, channeling information from various brain regions to the cerebral cortex, as well as a filter, prioritizing certain signals over others based on current physiological...
