Cerebellum: Anatomical Regions

5.0K
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. The...

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...

Major Somatic Sensory Pathways

3.1K
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...

Cerebral Hemispheres01:05

Cerebral Hemispheres

2.7K
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...

Seizures: Classification01:13

Seizures: Classification

1.8K
Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Cerebrum: Anatomical Overview II

Each cerebral hemisphere can be divided into three main regions. The outermost region, the cerebral cortex, is a thin layer (2 to 4 millimeters thick) made up of gray matter, consisting of neuron cell bodies, dendrites, glial cells, and blood vessels. The middle region, or white matter, is primarily composed of myelinated nerve fibers organized into three types of large tracts: association fibers, commissures, and projection fibers. Association fibers connect different areas within the same...

Summary

Cerebellar seizures, non-epileptic events caused by brainstem compression, can mimic seizures but originate from the cerebellum. Accurate diagnosis is crucial to avoid incorrect treatment in critical pediatric cases.

Area of Science:

  • Neurology
  • Pediatrics
  • Neurophysiology

Background:

  • Acute brainstem compression or increased intracranial pressure can trigger non-epileptic events.
  • These events, termed

Observation:

  • Two pediatric cases presented with cerebellar fits due to diffuse edema and brainstem compression.
  • One case involved a 10-year-old girl with acute disseminated encephalomyelitis (ADEM).
  • The second case involved a 2-year-old girl with Fallot tetralogy and severe respiratory distress.

Findings:

  • Cerebellar fits manifest as tonic seizures, axial rigidity, motor automatism, and paroxysmal decerebrate/decorticate posturing.
  • Electroencephalogram (EEG) shows diffuse, asynchronous slow waves during these events.
  • The underlying mechanism involves cerebellar herniation and brainstem compression, not cortical origin.

Implications:

  • Misdiagnosis of cerebellar fits can lead to inappropriate therapeutic interventions.
  • Prompt recognition is vital for managing these life-threatening pediatric neurological events.
  • Understanding the non-cortical origin is key for effective clinical management and treatment strategies.
