Research note: a resting-state, cerebello-amygdaloid intrinsically connected network

Cerebellum & Ataxias
Christophe Habas

Abstract

Previous ROI-based functional connectivity studies found functional coherence between cerebellum and cerebral amygdale, at rest. Moreover, some neurospychiatric symptoms were accompanied by abnormal activations of these two brain areas. Therefore, the aim of the study was to identify a putative, resting-state intrinsically connected cerebello-amygdaloid network. ICA-based analysis was performed on brain resting-state functional images of 15 volunteers. The first ICA spatial component corresponded to a circuit including: dentate nuclei, lobules VI and VIII, the basolateral amygdala, the substantia nigra, the posterior insula, claustrum and the parietal opercule. A new intrinsically connected network linking cerebellum and amygdala is described, which could be in charge of sensorimotor, emotional and motivational integration of somesthesic stimuli before recruiting more specialized circuits such as ventral striatum or attentional and salience networks.

Amygdala and Midbrain Dopamine

The midbrain dopamine system is widely studied for its involvement in emotional and motivational behavior. Some of these neurons receive information from the amygdala and project throughout the cortex. When the circuit and transmission of dopamine is disrupted symptoms may present. Here is the latest research on the amygdala and midbrain dopamine.

Amygdala: Sensory Processes

Amygdalae, nuclei clusters located in the temporal lobe of the brain, play a role in memory, emotional responses, and decision-making. Here is the latest research on sensory processes in the amygdala.

Basal Ganglia

Basal Ganglia are a group of subcortical nuclei in the brain associated with control of voluntary motor movements, procedural and habit learning, emotion, and cognition. Here is the latest research.
