Sequencing

A figure walks along a long road with a gene-sequence-like pattern.

How long-read sequencing will transform neuroscience

New technology that delivers much more than a simple DNA sequence could have a major impact on brain research, enabling researchers to study transcript diversity, imprinting and more.

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?
