What infant fMRI is revealing about the developing mind
Cognitive neuroscientists have finally clocked how to perform task-based functional MRI experiments in awake babies—long known for their inability to lie still or take direction. Next, they aim to watch cognition take shape and settle a debate about our earliest memories—with one group publishing a big clue today.

Molecular changes after MECP2 loss may drive Rett syndrome traits
Knocking out the gene in adult mice triggered up- and down-regulated expression of myriad genes weeks before there were changes in neuronal function.

Single-neuron recordings are helping to unravel complexities of human cognition
As this work begins to bear fruit, researchers “are becoming less afraid to ask very difficult questions that you can uniquely ask in people.”

Targeting NMDA receptor subunit reverses fragile X traits in mice
The subunit acts as a “volume control” on signaling that shapes the density of dendritic spines, the new work suggests.

Coding bonus: Bats’ hippocampal cells log spatial, social cues
The neurons represent not only an animal’s place in space, but also the distinguishing features of its fellow bats, including their sex and social status.

Remembering Eleanor Maguire, ‘trailblazer’ of human memory
Maguire, mastermind of the famous London taxi-driver study, broadened the field and championed the importance of spatial representations in memory.

How to teach this paper: ‘Coordination of entorhinal-hippocampal ensemble activity during associative learning,’ by Igarashi et al. (2014)
Kei Igarashi and his colleagues established an important foundation in memory research: the premise that brain regions oscillate together to form synaptic connections and, ultimately, memories.

Mitochondrial ‘landscape’ shifts across human brain
Evolutionarily newer regions sport mitochondria with a higher capacity for energy production than older regions, according to the first detailed map of the organelles in a tissue slice, adding to mounting evidence that the brain features a metabolic gradient.

This paper changed my life: Shane Liddelow on two papers that upended astrocyte research
A game-changing cell culture method developed in Ben Barres’ lab completely transformed the way we study astrocytes and helped me build a career studying their reactive substates.
