New paper out today w @dalmaijer.bsky.social @barbaraklump.bsky.social and @lucymaplin.bsky.social as part of the Phil Trans special issue doi.org/10.1098/rstb.... Over 2 years, we studied a population of cockatoos thought to be the source of the innovation of bin-opening.

snRNA-seq of Huntingtonโ€ฒs disease mice reveals vulnerability profiles of cortical cell types A common feature of neurodegeneration is selective vulnerability, where certain neurons succumb to disease, while others remain spared. The molecular underpinnings of these differences remain elusive....

New preprint from the lab by Dennis Feigenbutz et al.: Using #snRNA-seq, we explore vulnerability profiles of cortical cell types in #HuntingtonsDisease mice and identify ER-phagy as a new pathway in HD pathogenesis.

With @tomtom-auer.bsky.social team, we asked how #evolution reshapes what animals #eat to match their ecological niches. Using pan-neuronal Ca2+ imaging, we show that the changes are in how the brain processes #taste.

A parabrachial hub for need-state control of enduring pain - Nature Activity in a set of parabranchial neurons in the mouse brain is increased during chronic pain, predicts coping behaviour, and can be modulated by circuits activated by survival threats.

Finally out: our recent work with Nick Betley is a view into how the brain reshapes its behavior in the face of competing survival needs- and also a potential angle on treatment targets for enduring pain.

A brief rundown...

Maternal aggression driven by the transient mobilisation of a dormant hormone-sensitive circuit - Nature Communications Mothers can fiercely defend their young, but how the brain triggers this response remains to a large extent a mystery. Here, authors show that a dormant, hormone-sensitive brain circuit switches on to spark maternal aggression during the lactation period.

1/n. New paper from us: here we explore the mechanisms underlying maternal aggression in mice as a means of addressing how an individual transiently can gain access to a behaviour normally outside of its repertoire. Lead investigator Stefanos Stagkourakis (not on ๐Ÿฆ‹)๐Ÿงต:
