Shyness May Originate in the Cerebellum

New research reveals that trait shyness is linked to reduced spontaneous neural activity in the cerebellum, a brain region traditionally associated with motor control but increasingly recognized for its role in emotion and social cognition. Using resting-state fMRI and ReHo analysis, researchers found that shy individuals exhibited lower synchrony in the cerebellar Crus I region.

Targeting the Cerebellum Could Ease Alcohol Withdrawal Symptoms

Researchers have identified the cerebellum as a promising target for easing alcohol withdrawal, the stage of alcohol use disorder that drives many people back to drinking. In mice, withdrawal symptoms were alleviated by calming overactive cerebellar neurons, either through genetic tools or a synthetic compound.

This shows a child, an MRI machine, and a brain.

Cerebellum Shapes Children’s Empathy and Theory of Mind

Understanding others’ beliefs—especially false ones—is key to human communication and begins to develop between ages three and five. In a new study, researchers observed children’s brain activity while they watched movies in an MRI scanner to investigate the neurological roots of Theory of Mind (ToM).

Mitochondrial Link to Cerebellar Decline in MS

A new study reveals that mitochondrial dysfunction plays a central role in the loss of Purkinje neurons in the cerebellum, contributing to motor impairments in people with multiple sclerosis (MS). Researchers found that inflammation and demyelination in the cerebellum disrupt the mitochondria—key cellular power sources—leading to energy loss, neuron damage, and ataxia.

Cerebellum Plays Key Role in Social and Cognitive Abilities

The cerebellum, traditionally linked to motor functions, also plays a vital role in social and cognitive abilities, according to new research. Abnormalities in this brain region not only impair movement but are linked to emotional and behavioral issues, particularly in autism.

Cerebellum Plays Crucial Role in Skill Retention and Memory

New research uncovers that the cerebellum is critical for long-term motor skill memory formation, distinguishing it from short-term memory systems. Patients with cerebellar damage showed normal performance on motor tasks over short intervals but were impaired with longer gaps, linking the cerebellum directly to long-term sensorimotor memory. These findings resolve inconsistencies in prior studies and highlight the importance of time intervals in understanding motor memory degradation in cerebellar degeneration.

Cerebellum Controls Thirst, Not Just Motor Functions

A new study reveals the cerebellum's role in controlling thirst, expanding its known functions beyond motor control. Researchers discovered that the hormone asprosin activates Purkinje neurons in the cerebellum, driving the urge to drink water. This finding could lead to new treatments for thirst disorders. The study highlights the cerebellum's broader impact on essential survival functions.

Cerebellum Plays A Key Role in Reward Learning

Researchers discovered the cerebellum's significant involvement in reward-based learning, challenging longstanding views of its function. By training monkeys to associate visual cues with hand movements for rewards, the study demonstrates that the cerebellum is essential for forming new visuomotor associations, not just controlling movement.

Zombie Neurons: Unlocking the Cerebellum’s Learning Secrets

Researchers have identified "zombie neurons" in the cerebellum that offer new insights into how this brain region facilitates learning through past experiences. Utilizing optogenetics, the team manipulated cerebellar inputs, specifically climbing fibres, to demonstrate their pivotal role in associative learning processes, such as the conditioned blinking response in mice.

Link Between Smaller Cerebellum and PTSD

New research uncovered a significant association between posttraumatic stress disorder (PTSD) and a reduction in cerebellar volume. This study, one of the largest of its kind, demonstrates that individuals with PTSD have cerebellums that are approximately 2% smaller than those without the disorder.
