Widely used calcium imaging protocol can lead to spurious results, new paper cautions
The technique, which measures calcium currents as a proxy for neuronal firing, sometimes reports unusual and potentially misleading waves of activity in the hippocampus.

Knowledge graphs can help make sense of the flood of cell-type data
These tools, widely used in the technology industry, could provide a foundation for the study of brain circuits.

The brains are colored to suggest land masses and bodies of water.](https://www.thetransmitter.org/wp-content/uploads/2024/05/Cell-Taxonomy-1200-1024x692.webp)

Rat neurons thrive in a mouse brain world, testing ‘nature versus nurture’
Neurons from the two rodents can wire up together to form functional circuits—all while maintaining some species-specific properties, two new studies show.

Where do cell states end and cell types begin?
High-throughput transcriptomics offers powerful new methods for defining different types of brain cells. But we need to think more explicitly about how we use these data to distinguish a cell’s permanent identity from its transient states.

Building a brain: How does it generate its exquisite diversity of cells?
High-throughput technologies have revealed new insights into how the brain develops. But a truly comprehensive map of neurodevelopment requires further advances.

Individual neurons tune to complex speech sounds and cues
Neuropixels arrays implanted in people reveal nuances of speech perception and production that confirm results from brain-surface recordings and can even predict what someone is about to say.

In hot water: Climate change tests limits of neuronal resilience in crabs
Warming seas disrupt the function of neurons — and could seed permanent changes in marine species, according to studies of a circuit that controls digestion in crustaceans.

We found a major flaw in a scientific reagent used in thousands of neuroscience experiments — and we’re trying to fix it.
As part of that ambition, we launched a public-private partnership to systematically evaluate antibodies used to study neurological disease, and we plan to make all the data freely available.
