Social-media attention this week centered on two new studies of the brain’s memory hub: One employed virtual reality to probe how people use and update their cognitive maps, and the other tracked individual hippocampal neurons in mice as they learned.

A pair of neuroimaging-related studies — one about a framework for brain-wide association studies and another about a standardized tool to image rat brains — held researchers’ attention on social media this week.

Discussion on social media revolved around a meta-analysis of suicidality in autism, a method to purify neural stem and progenitor cells, and autism-linked genes in zebrafish.

Researchers took to Twitter this week to discuss the most complete map of brain structure to date — that of a larval fruit fly — and the largest-yet human brain connectivity resource.

Three murine studies — two of cell types in the mouse brain plus a look at behavioral sex differences — dominated researchers’ attention on Twitter this week.

The research community was abuzz this week with chatter about Nature’s new policy on registered reports, a 3D genome atlas of the cerebellum, and a study that measured brain activity in freely moving octopuses.

This week, researchers on Twitter discussed false results in gene expression studies, a wearable neuron-recording device, and paper-publishing requirements.

Tweets this week consider new research on how rare gene variants contribute to complex traits and microglia change their shape, plus views on diagnosing autism virtually.

This week’s newsletter considers tweets about the assumptions baked into brain-imaging studies; the reach of brain waves; and a diet-based intervention for a rare autism-linked condition.

Conversation took off this week around precision in neuroscience measurements, a new strategy to rescue Rett neurons, autism insights from protein interactomes, and mechanisms of touch perception.
