‘Understudied secret’ in brain dampens nicotine drive in mice
The interpeduncular nucleus produces an aversion to nicotine, even at low doses, and helps moderate how rewarding mice find the drug.

Escaping groupthink: What animals’ behavioral quirks reveal about the brain
Neuroscientists have long ignored the variability in animals’ behavioral responses in favor of studying differences across groups. But work on the brain differences that underlie that variability is beginning to pay off.

Basic pain research ‘is not working’: Q&A with Steven Prescott and Stéphanie Ratté
Prescott and Ratté critique the clinical relevance of preclinical studies in the field and highlight areas for improvement.

Too much or too little brain synchrony may underlie autism subtypes
Functional connectivity differences in autism mouse models point to two subtypes that correspond to patterns seen in some people with the condition.

In vivo veritas: Xenotransplantation can help us study the development and function of human neurons in a living brain
Transplanted cells offer insight into human-specific properties, such as a lengthy cortical development and sensitivity to neurodevelopmental and neurodegenerative disease.

Lions and tigers and bears: Long-lived zoo animals offer a promising venue to study mental health and neurodegenerative disorders
These animals’ lifestyles often mirror those of people, making them a more relevant milieu than lab mice for determining how environmental factors influence mental health and cognitive decline. Studying them could improve animal welfare in the process.

How tiny tardigrades could help tackle systems neuroscience questions
The eight-legged, millimeter-long animals reveal how small nervous systems produce complex behaviors and perceptual abilities, a preprint suggests.

Soft touch quells loneliness in mice
Touch modulates one of two dueling types of hypothalamic neurons that, thermostat-like, balance an animal’s drive for social interaction.

Dopamine ‘gas pedal’ and serotonin ‘brake’ team up to accelerate learning
Mice learn fastest and most reliably when they experience an increase in dopamine paired with an inhibition of serotonin in their nucleus accumbens, a new study shows, helping to resolve long-standing questions about the neuromodulators’ relationship.

Plaque levels differ in popular Alzheimer’s mouse model depending on which parent’s variants are passed down
5XFAD model mice that inherit two disease-related genes from their fathers have double the plaques seen in those with maternal inheritance, a new study shows.

Sounding the alarm on pseudoreplication: Q&A with Constantinos Eleftheriou and Peter Kind
Most studies of neurological disorders in mice erroneously treat multiple samples from a single animal as independent replicates, according to a new analysis. But scientists and journals can take steps to curb this practice.
