Persistent protein pairing enables memories to last

The complex of two memory proteins, rather than the individual molecules acting independently, underlie month-long memories in mice, a new study suggests.

How to teach this paper: ‘Behavioral time scale synaptic plasticity underlies CA1 place fields,’ by Bittner and Milstein et al. (2017)

Katie Bittner, Aaron Milstein and their colleagues found that cellular learning can happen over longer timescales than Hebb’s rule predicts. How long should we wait to teach students about this phenomenon?

What, if anything, makes mood fundamentally different from memory?

To better understand mood disorders—and to develop more effective treatments—should we target the brain, the mind, the environment or all three?

‘It must be something I ate’ is hard-wired into the brain

Feeling sick reactivates “novel flavor” neurons, according to a new study in mice, and points to a dedicated circuit for learning to avoid unsafe food.

Neurons making memories shush their neighbors

When neurons strengthen their synapses, they “infect” surrounding cells with a virus-like protein to weaken those cells’ excitatory connections, according to a new preprint.

Learning or performance? Why the distinction matters for memory science

New methods make it possible to probe the neural substrates of memory with unprecedented precision. Making the most of them demands careful experimental design.
