Major Somatic Sensory Pathways01:28

Major Somatic Sensory Pathways

943
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...

Cerebellum: Anatomical Regions

1.6K
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...

Diencephalon: Thalamus and Information Relay

1.5K
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...

Role of Cerebellum and Prefrontal Cortex in Memory01:14

Role of Cerebellum and Prefrontal Cortex in Memory

418
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...

Cerebral Hemispheres01:05

Cerebral Hemispheres

324
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...

Cerebrum: Anatomical Overview II01:11

Cerebrum: Anatomical Overview II

1.6K
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...

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Computational Psychiatry

Background:

  • The cerebellum modulates motor, cognitive, social, and affective functions.
  • It interacts with the cerebral cortex, basal ganglia, and spinal cord for automatic behaviors.
  • Cerebellar predictive mechanisms extend beyond sensorimotor to reward-related tasks.

Purpose of the Study:

  • To explore the cerebellum's role in reward processing, prediction error encoding, and its implications for mental health.
  • To highlight the cerebellum's function in constructing internal models and predictive behavior.
  • To investigate cerebellar contributions to cognitive learning and emotional regulation.

Main Methods:

  • Review of existing literature on cerebellar function in reward processing and cognitive tasks.
  • Analysis of neuroimaging and neurophysiological studies.
  • Examination of clinical evidence from mood, addiction, and eating disorders.

Main Results:

  • Cerebellar circuits encode temporal difference and reward prediction errors.
  • Catecholamines in the cerebellum modulate cognitive learning and complex behaviors.
  • Specific cerebellar regions (lobules VI-VII/vermis) are implicated in loss aversion and reward sensitivity.
  • Cerebellar dysconnectivity is observed across mood states, linked to mental disorders.
  • Cerebellar patients exhibit aberrant social behavior, impulsivity, and compulsivity.

Conclusions:

  • The cerebellum is a central hub for reward mechanisms, working with the striatum, VTA, and PFC.
  • It constructs internal models, predicts behavioral impacts, and compares predictions with actual outcomes.
  • The cerebellum's role in prediction extends to longer time scales, influencing adaptive homeostatic processes and mental health.
