Diurnal variation loss of pineal allopregnanolone synthesis by light-at-night induces pituitary adenylate cyclase-activating polypeptide (PACAP) reduction and transcriptional PACAP repression in the cerebellum, with subsequent Purkinje cell death.

Non-synaptic extracellular vesicles may be involved in the release of endogenous cannabinoids in the central nervous system thereby representing a novel mechanism to mediate their effects on synaptic transmission.

Imaging and laboratory-induced psychosocial stress showed that exposure to psychosocial adversity was associated with dampened striatal dopaminergic function alongside blunted physiological yet potentiated subjective responses to acute stress.

A fundamental visual computation, the establishment of ON selectivity, is established across distributed circuits, allowing for more robust and flexible coding than suggested by core circuit motifs.
Motor and non-motor functions are represented in spatially segregated and temporally organized climbing fiber signals to distinct cerebellar zones during goal-directed behavior.
Cerebellar climbing fibers can generate learned reward-predictive instructional signals, suggesting a role for cerebellar learning in the reinforcement of reward-driven behaviors.
Electrophysiological recordings in monkeys reveal that cerebellar complex spikes encode future reward size when reward information is first made available, but not during reward delivery or smooth pursuit eye movement.

NMDA receptors on PV+ interneurons mediate supralinear integration at feedback synapses from local pyramidal neurons, enabling competing networks to ‘lock’ onto salient inputs.

An intersectional genetic vector approach allows the identification and characterization of novel hippocampal inhibitory neurons with both broad local connectivity within CA1 and long-range projections to several extrahippocampal areas.
