A cortical locus for modulation of arousal states

This study identifies the anterior cingulate cortex (ACC) as a key cortical region modulating arousal states through optogenetic experiments and behavioral measurements.

System-wide dissociation of reward and aversive dopaminergic signals

The paper investigates dopamine signaling in mice during reward and aversive tasks, finding distinct spatial patterns and encoding mechanisms for reward and aversive signals.

Cortical astrocytes extend phasic norepinephrine signals and critically mediate learned behavior

The paper shows that cortical astrocytes mediate learned behavior by extending norepinephrine signals through calcium dynamics and ATP release, influencing neuronal encoding of task variables.

Diverse ancestral brainstem noradrenergic neuron activity across species and biological factors

This study analyzes LC neuron firing patterns across species and biological factors, revealing diverse activity patterns and subregions enriched for specific factors and disease models.

Distinct prefrontal top-down circuits differentially modulate sensorimotor behavior

This study identifies distinct roles of prefrontal cortex projections in modulating sensorimotor behavior through separate circuits for motor response coordination and sensory cue processing.

Imprinted maternally-expressed microRNAs antagonize paternally-driven gene programs in neurons

The paper shows maternally-expressed miRNAs repress paternally-driven genes in neurons, suggesting imprinted miRNAs mediate parental genomic conflict.

Active control of arousal by a locus coeruleus GABAergic circuit

This study identifies a GABAergic circuit in the locus coeruleus that modulates arousal by controlling the gain and tone of noradrenergic activity through coincident and non-coincident inputs.

Locally coordinated synaptic plasticity shapes cell-wide plasticity of visual cortex neurons in vivo

The paper shows that local synaptic plasticity, mediated by Arc, coordinates potentiation and depression of adjacent spines to shape functional neuronal responses in vivo.
