Neural basis of why mammals eat more in the cold
Feeding and the maintenance of internal body temperature are tightly linked in warm-blooded animals, and mammals eat more in the cold to maintain their body heat. Experiments reveal that a small nucleus in the brain’s thalamus controls feeding behaviour specifically in cold conditions by directly activating a reward centre in the brain.

Replication study casts doubt on magnetic sensing in flies
It has long been thought that the fly Drosophila melanogaster can detect Earth’s magnetic field and offers an ideal system in which to examine this enigmatic sense. However, a rigorous replication of key studies fails to support this idea.

A battle between neural circuits for infanticide and maternal-care behaviours
A previously unknown neural circuit in the brains of female mice is activated during infanticidal behaviour, and reciprocally inhibits another circuit that promotes maternal-care behaviour. These circuits show opposing changes in excitability when female mice become mothers, explaining the switch in young-directed behaviours that occurs with motherhood.

Birdsong sequences initiated by a small cluster of cells in the brain
The zebra finch’s courtship song consists of a fixed sequence of vocal elements called syllables. A small structure in the thalamus, deep in the brain, forms connections with a set of nerve cells that become active at the beginning of syllables, thereby initiating components of the finch’s vocal repertoire.
