Back to front: cerebellar connections and interactions with the prefrontal cortex
TLDR
The results demonstrate the presence of a cerebello-prefrontal pathway in rat and reveal behaviorally dependent coordinated network activity between the two structures, which could facilitate transfer of sensorimotor information into ongoing neocortical processing during goal directed behaviors.
Electrophysiological Mapping of Novel Prefrontal – Cerebellar Pathways
TLDR
In vivo electrophysiological methods in anaesthetized rats are used to establish a physiological basis for communication between the medial prefrontal cortex (prelimbic subdivision, PrL) and the cerebellum, and show that prelimbic cortical stimulation elicits complex spikes in lobule VII Purkinje cells, indicating transmission via a previously undescribed cerebro-olivocerebellar pathway.
Neural Correlates of Fear in the Periaqueductal Gray
The dorsal and ventral periaqueductal gray (dPAG and vPAG, respectively) are embedded in distinct survival networks that coordinate, respectively, innate and conditioned fear-evoked freezing.
Optoactivation of Locus Ceruleus Neurons Evokes Bidirectional Changes in Thermal Nociception in Rats
TLDR
The LC is capable of exerting potent, discrete, bidirectional influences on thermal nociception that are produced by specific subpopulations of noradrenergic neurons, which reflects an underlying functional heterogeneity of the influence of the LC on the processing of nocICEptive information.
Neural substrates underlying fear-evoked freezing: the periaqueductal grey–cerebellar link
TLDR
Evidence that activation of the vlPAG causes an increase in α‐motoneurone excitability, consistent with a role in generating muscle tone associated with fear‐evoked freezing, is provided.
The Periaqueductal Gray Orchestrates Sensory and Motor Circuits at Multiple Levels of the Neuraxis
TLDR
It is suggested that the interactions revealed in the present study could form the neural substrate for survival behaviors associated with vlPAG activation, and provide insights into the neural circuits that enable an animal to be ready and able to react to danger, thus assisting in survival.
Translational neurophysiology in sheep: measuring sleep and neurological dysfunction in CLN5 Batten disease affected sheep
TLDR
The validity of an ovine model of Batten disease is demonstrated by revealing in vivo EEG abnormalities that resemble those in affected children.
Anatomical and physiological foundations of cerebello-hippocampal interaction
TLDR
A novel neural network macro-architecture is revealed through which the cerebellum may influence hippocampal neuronal activity and related functions, such as spatial navigation, through subregion-specific synchronization of neuronal oscillations in the 6–12 Hz frequency range.
The olivo-cerebellar system and its relationship to survival circuits
TLDR
Evidence suggesting that the olivo-cerebellar system may link to survival networks via interactions with the midbrain periaqueductal gray, a structure with a well known role in expression of survival responses is focused on.
Transmission of Predictable Sensory Signals to the Cerebellum via Climbing Fiber Pathways Is Gated during Exploratory Behavior
TLDR
The results indicate that the gating is related to the level of predictability of a sensory signal, and a major route for peripheral information to gain access to the cerebellum is via ascending climbing fiber pathways.
