This paper changed my life: Victoria Abraira on a tasty link between circuits and behavior

The findings from Charles Zuker’s lab put the taste system on the map, revealing that some fundamental principles of behavior are hardwired.

Systems and circuit neuroscience need an evolutionary perspective

To identify fundamental neuroscientific principles that generalize across species, neuroscientists must frame their research through an evolutionary lens.

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.

‘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.

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.

PTEN problems underscore autism connection to excess brain fluid

Damaging variants in the autism-linked gene cause congenital hydrocephalus—a buildup of cerebrospinal fluid in the brain—by turbocharging a downstream signaling pathway that promotes the growth of cells, according to a new study.
