AI Article Synopsis

  • Research indicates that the cerebellum plays a role in social behavior and mentalizing, which involves recognizing others' mental states.
  • A study used cerebellar transcranial direct current stimulation (tDCS) on 23 participants to analyze their brain activity while performing tasks involving social action sequences.
  • Results showed that tDCS impaired task performance and decreased activation in key brain areas associated with mentalizing, particularly for true belief sequences, highlighting the cerebellum's influence on social cognition.

Article Abstract

Research on the involvement of the cerebellum in social behavior and its relationship with social mentalizing has just begun. Social mentalizing is the ability to attribute mental states such as desires, intentions, and beliefs to others. This ability involves the use of social action sequences which are believed to be stored in the cerebellum. In order to better understand the neurobiology of social mentalizing, we applied cerebellar transcranial direct current stimulation (tDCS) on 23 healthy participants in the MRI scanner, immediately followed by measuring their brain activity during a task that required to generate the correct sequence of social actions involving false (i.e., outdated) and true beliefs, social routines and non-social (control) events. The results revealed that stimulation decreased task performance along with decreased brain activation in mentalizing areas, including the temporoparietal junction and the precuneus. This decrease was strongest for true belief sequences compared to the other sequences. These findings support the functional impact of the cerebellum on the mentalizing network and belief mentalizing, contributing to the understanding of the role of the cerebellum in social sequences.

Loss of function in the subunits of the GTPase-activating protein (GAP) activity toward Rags-1 (GATOR1) complex, an amino-acid sensitive negative regulator of the mechanistic target of rapamycin complex 1 (mTORC1), is implicated in both genetic familial epilepsies and Neurodevelopmental Disorders (NDDs) (Baldassari et al., 2018). Previous studies have found seizure phenotypes and increased activity resulting from conditional deletion of GATOR1 function from forebrain excitatory neurons (Yuskaitis et al.

Article Synopsis
  • Autism spectrum disorder (ASD) is a serious neurodevelopmental issue, and this study investigates the effects of administering MSCs-derived exosomes after birth on a rat model of ASD.
  • The research involved dividing male rat pups into control, VPA (exposed to a neurotoxin), and VPA treated with exosomes, assessing changes in behavior and cerebellar structure.
  • Results showed that VPA groups exhibited increased activity, social impairments, and disrupted cerebellar structure, while those treated with exosomes showed improvements in histological integrity and behaviors, supported by changes in specific signaling pathways.

The cerebellum, identified to be active during cognitive and social behavior, has multisynaptic connections through the cerebellar nuclei (CN) and thalamus to cortical regions, yet formation and modulation of these pathways are not fully understood. Perineuronal nets (PNNs) respond to changes in local cellular activity and emerge during development. PNNs are implicated in learning and neurodevelopmental disorders, but their role in the CN during development is unknown.

The cerebellum is activated by noxious stimuli and pathological pain but its role in noxious information processing remains unknown. Here, we show that in mice, cutaneous noxious electrical stimuli induced noradrenaline (NA) release from locus coeruleus (LC) terminals in the cerebellar cortex. Bergmann glia (BG) accumulated these LC-NA signals by increasing intracellular calcium in an integrative manner ('flares').

Article Synopsis
  • There is a significant sex bias in autism spectrum disorder (ASD), with 80% of cases diagnosed in males, making it challenging to uncover the biological reasons behind this difference.
  • Loss of function mutations leading to dysregulated mTORC1 signaling are prevalent in individuals with tuberous sclerosis (TSC), and over 50% of those with TSC are also diagnosed with ASD, indicating a strong genetic link.
  • In experiments with mice, it was found that while motor coordination deficits are similar in both male and female mice, social interaction impairments are significantly worse in males, suggesting that certain behavioral issues in ASD may vary based on sex.
