Differential mechanisms underlie trace and delay conditioning in Drosophila
Trace and delay conditioning experiments in Drosophila reveal the different neurons and signalling mechanisms that underlie this behaviour and highlight similarities with observations of learning experiences in mammals.

Shared mechanisms underlie the control of working memory and attention
The prefrontal cortex in monkeys controls working memory in a similar way to attention, by selectively transforming the representations of remembered items.

Hidden neural states underlie canary song syntax
Neurons in the canary premotor cortex homologue encode past song phrases and transitions, carrying information relevant to future choice of phrases as ‘hidden states’ during song.

Posterior parietal cortex represents sensory history and mediates its effects on behaviour
A working memory task in rats demonstrates that the posterior parietal cortex is a critical locus for the representation and use of prior stimulus information.

Impaired hippocampal–prefrontal synchrony in a genetic mouse model of schizophrenia
A deletion on human chromosome 22 (22q11.2) is one of the largest genetic risk factors for schizophrenia. Mice with a corresponding deletion have problems with working memory, one feature of schizophrenia. It is now found that these mice also show disruptions in synchronous firing between neurons of the prefrontal cortex and of the hippocampus, an electrophysiological phenomenon that has been linked to learning and memory and which is also thought to be disrupted in schizophrenia patients.
