Midbrain neurons regulate the production of courtship squeaks in female mice

The paper identifies midbrain PAG neurons that regulate courtship squeaks in female mice but not pain-elicited squeaks, suggesting distinct neural pathways for different vocalizations.

Presence of a home cage running wheel, but not wheel running per se, decreases social motivation in adult C57BL/6J female mice

This study shows that having a running wheel in the home cage, not the act of running, reduces social motivation in adult female mice during same-sex interactions.

Production of mouse ultrasonic vocalizations and distress calls is associated with different patterns of Fos expression in the nucleus retroambiguus

The paper investigates Fos expression patterns in the nucleus retroambiguus during mouse ultrasonic vocalizations and distress calls, identifying distinct neuronal populations associated with each vocalization type.

Vocal ontogeny in Mus musculus

This study identifies the age range when juvenile mice transition from producing isolation ultrasonic vocalizations to social ultrasonic vocalizations during development.

Same-sex mounting in single-housed C57BL/6J female mice is not coupled to estrous state

This study shows that same-sex mounting in single-housed C57BL/6J female mice is not influenced by the estrous state of either the mounter or the stimulus female.

The infralimbic, but not the prelimbic cortex is needed for a complex olfactory memory task.

The study shows that infralimbic cortex, but not prelimbic cortex, is required for resolving retroactive interference in a complex olfactory memory task.

Short-term social isolation acts on hypothalamic neurons to promote social behavior in a sex- and context-dependent manner

The paper identifies hypothalamic neurons that promote social behavior after short-term isolation, showing sex- and context-dependent effects.

Rates of female mouse ultrasonic vocalizations are low and are not modulated by estrous state during interactions with muted males

This study finds that female mice produce low rates of ultrasonic vocalizations during courtship and that these rates are not influenced by estrous state when interacting with muted males.

Effects of short-term isolation on vocal and non-vocal social behaviors in prairie voles

This study examines short-term social isolation effects on vocal and non-vocal social behaviors in prairie voles, finding no overall impact but sex- and context-specific changes in aggression.

Different populations of midbrain neurons control the production of distinct acoustic categories of vocalization

The paper shows that distinct midbrain neuron populations control different acoustic categories of vocalizations in mice.

Circuit and synaptic organization of forebrain-to-midbrain pathways that promote and suppress vocalization

The paper identifies two forebrain inhibitory neuron populations that trigger or suppress vocalization by modulating PAG-USV neurons through distinct synaptic mechanisms.

Identification of midbrain neurons essential for vocal communication

The paper identifies a specific subset of midbrain PAG neurons in male mice essential for producing ultrasonic vocalizations (USVs) and shows their role in vocal communication.
